Sequential turbo setup - Need Help Finding Part

[ericpaulyoung]

Ok, I am gathering parts for a sequential turbo setup on my 2.0, and need help finding a crucial part that seem to only exist in Poland and the Czech republic. Any help locating one of these mysterious beasts is very much appreciated. Here is a TDI discussion on using one in a sequential setup on a diesel.

And here is the part number = 059 145 901B

Here is a picture of it

And here are the schematic and part lookup. It is part 18. (thanks Martin)

Sequential turbos! Do you ever stop coming up with stuff Eric !?
Your the pioneer of the b7 section :thumbup:

I am definitely not the first to use this technology, but maybe the first on our platform. This is the combination I am thinking about right now. They should compliment each other quite well, and the plan is to keep my solid 2500-4500 rpm range of the GTX2863 and have the GT3582 roll in from 4000-redline. The spool characteristics is almost perfect with a 500 rpm overlap, and it should get me in the 450-500 awhp range up top. That's the plan at least.

[ericpaulyoung]

Well if this works I can post any drawings and part numbers etc. so the next guy can build the same setup if they want. It would be a cool kit too! I would love to see ATP watch this thread and then make a kit for everyone. Screw those Supras! They are so last year :)

Just got off the phone with my buddy in parts at a VW/Audi dealer.. he said he cannot order that part for import to the NA market or some BS.

But, I might be able to work something out lol.

That would be great. Everyplace I have asked said "nope, those don't ship to the US". ??

[viperdsa]

You could see if one of the non-US members would be willing to work with you and try to get it that way.

[AudiA4_20T]

You need to ask some guys like Alex@Europrice who get Euro shipments in

[F16HTON]

May not flow enough air to feed the larger turbo. Have you considered a butterfly valve such as a throttle body?

May not flow enough air to feed the larger turbo. Have you considered a butterfly valve such as a throttle body?

A guy asked the same question over in the TDI forum with this response "audi valve is more than big enough.. has only 11 mbar pressure drop at at 1000 kg/h (at 3 bar abs)". That would equate to 11 mbar dP at 277 g/s. Assuming the loss is not strongly Reynolds number dependent, the losses would scale proportional to v^2. Making a very approximate assumption of similar densities at the different flows (bad assumption, but just for rough guessing) then my goal of 400 g/s would have a loss of (400/277)^2*11mbar = 22.94 mbar losses. That is 0.33 psi of loss for the poppet valve. Definitely a big contributor, but acceptable. I think the intercoolers have about a 1 psi drop, so it is like added and additional 1/3 of an intercooler into the system.

[ericpaulyoung]

So this is the general overlay of a series sequential turbo setup with a larger low pressure turbo and smaller high pressure turbo chained together.

I feel like I'm a fairly knowledgeable member of our platform but every time I read the threads on epy's crazy new ideas all I can read is "hey I'm working on this things that's never been done before" then i try to keep reading it, even say it out loud and al my brain hears is derka derka blacka berk bang bung rabble rabble rabble

And then zoommmmmmmm way over my head and I feel like I just joined the forum yesterday

You my friend are a true innovator of our platform! You are setting the new standards of what the b7 2.0t is really capable of! [hail]

[aluthman]

I would love to see that setup get built. If anyone is going to pull it off, it will be EPY.

[PNW Avant]

I thought this was called a "compound turbo" setup?

[LoKisSpYdR]

No, it's typically referred to as a twin turbo, i.e. MkIV Toyota Supra Twin Turbo. Same setup. The new BMW 3series diesels use this setup as well.

[ericpaulyoung]

If you look through the linked PDF above you will see the differences.

Compound setups always rely on the high pressure turbo to compound the flow from the low pressure.

Traditional twins just dedicate a single turbo to a set of cylinders, and the other turbo to the rest.

Sequential is the most complex in that it relies on only the high pressure tirbo down low in the rpm's, and only the low pressure turbo at the high rpm's. Then there is an overlap region where you switch from one to the other and hopefully deliver a smooth transition. This requires the most control parts.

[aluthman]

What purpose exactly does that part serve? Why not do something like this?

http://i68.photobucket.com/albums/i17/paulvolk/twinturbo_large.jpg

[LoKisSpYdR]

Yeah don't get me wrong, Toyota or BMW calling what they call a twin turbo makes no sense, sequential turbos on an inline 6 setup wouldn't be a literal twin turbo by definition. This is why, I think, Audi decided to call it's twin turbo setup on the 2.7TT and 4.2TT, "Bi-Turbo", although, by definition, they were two identical turbo performing the same task at the same time - or twins.

[LoKisSpYdR]

http://i68.photobucket.com/albums/i17/paulvolk/twinturbo_large.jpg

Holy shit that thing has to get HOT!

Also, I'm pretty sure that's a compound turbo setup not sequential.

[ericpaulyoung]

That is a straight compound setup, and likely for a Diesel, as straight compounds make serious boost (like 40-200 psi!). I am looking to keep running around 30 psi, I just want 100 g/s more flow at 30 psi. That is beautiful though ;)

[aluthman]

Yeah, it says Cummins on the valve cover. It would be tits if you could get a setup like that to make 30ish psi though.

[ericpaulyoung]

You can! It's called a series sequential ;)

[canadianA4B7]

Damn you! I followed your lead on building the S3 k04 and i think ive done an ok job, was looking into some bigger turbos out of curiosity but figured id hold off. No you go and start talking about doing something like this! Looks like id bring this set up to canada as yer usually the first to complete these amazing set ups. Ill see if i can contact some germans and ask if they cay get that part.

[JTC85]

not trying to thread jack, just curious if anyone has attempted twincharging this motor?

[derrek]

Why not use a k04or k03 for the smaller turbo? To much of a gap in compressor maps maybe not enough flow to spool the bigger turbo? What are your going to do for fuel? Ive thought about doing something like this a few times but I always get stuck on what to do for fueling and if I want to go threw the headache of finding someone to tune it. I hope you get this setup running nice it would be an awesome seconded big turbo route!

[aluthman]

His GTX2863 already spools plenty fast, and he wants more flow on the top end. This means he needs something bigger than the GTX2863 for the big turbo.

[derrek]

I understand that he's going to run a sequential turbo set up. But if hes going this far why not use a smaller turbo then the 28 for the least amount of lag possible?

[aluthman]

I'm guessing that with the K03/K04 turbos having a one piece manifold/turbine housing, the fabrication would be a lot more difficult.

True, being a fabricator I always overlook these things.

[ericpaulyoung]

Not that I am aware of. It is fairly common in the big diesel truck community, and is even used in some OEM applications as mentioned above. Each applies it a little differently for different goals, but most people would just buy a different engine (e.g., 2.7tt) and swap it as the cost could be around 5k for the additional turbo, hardware, and fabrication costs. However, I started thinking about how nice it would be to keep factory ECU control over the car, and also about the fact that we have a little extra space under our hood with the little four cylinder, and this seems to fit :)

Actually this would be best, and I was thinking a GT2560R would be perfect as the thing is basically spooling at idle :) Also it is a smaller package and makes the fitment better too. However, I already own a GTX2863 and it is fit really nice already, so I am thinking to just build on that. There is a chance I go with the little guy, and if I did it from the start I would definitely evaluate it further. However, the 2863 is a pretty fast spool and the way that it can run up into the GT35 lower range should give me a very smooth transition between the two without having to use active change over. So the plan is to rely on the large overlap in performance to allow me to just run the TDI biturbo bypass valve as a passive change over as the ECU opens up the wastegate the high pressure turbo to control charge, then the low pressure will be running alone and the high pressure turbo will just be free wheeling.

hehe, yup! I do wish that I got the "stock" location kit from ATP now, as it moves the turbo forward like 4", and that would give me a lot more room to run the exhaust connection from the first turbo to the second, and then another exhaust back to the downpipe. With the kit I have, it is going to be a really tight fit. Thinking I may have to have the two exhaust pipes welded together. Also considering flexible connections between the first and second turbo so that you can actually put the sequential turbo onto any other BT kit by simply removing the airbox, and adding in the sequential turbo as a "kit". That should make it easier for people to copy my design for themselves. Then we would truly have another "Stage" after going BT. I am thinking:

Stage 1 - tune
Stage 2 - upgraded fueling and air management (intake, exhaust, etc.)
Stage 3 - upgraded first turbo (K04, GTX, EFR)
Stage 4 - adding second sequential turbo

I'm glad to see someone else has the same idea as me! Keep up the awesome work Eric. I come from the diesel world where it
was all about sequential turbos or true twins and I was disappointed to see nobody really attempting it on the 2.0T.

I mean....we have like 2 OTS turbo kits available, k04/k0r/frankenturbo, gtx/gt28. It looks like 5 turbo options but really it's a pretty limited platform right now, I don't think anyone has come out with a compound kit for a b6 or even a b5. We've seen USP make one car, but never release a kit, It's gotta be a total bitch of a project.

Any help would be greatly appreciated, as I have never tried this before. My plan is to basically copy the Audi design with the passive poppet check valve, and to just use the wastegate on the high pressure turbo as the switch over. To flow enough air, I will make this a TIAL 44 or similar.

http://i1073.photobucket.com/albums/w381/ericpaulyoung/audibiturboschematic_zps34beaf46.jpg

The process would be like this. Tune the ECU for 23 psi, and have it only control the boost via the high pressure turbo wastegate duty. The low pressure turbo wastegate would be run with a manual boost controller. So the spin up would be as follows.

1. go throttle from low load
2. as we roll up to 3000 rpms the high pressure turbo comes up to 23 psi, and the ECU starts brings up the wastegate duty cycle until it is sufficient for maintaining 23 psi.
3. the low pressure turbo is starting to spool and by 3000 rpms is around 15 psi of boost so it cannot overcome the poppet valve and helps the high pressure turbo hit 23 psi even faster
3. as we go past 3500 rpms, the duty cycle has to decrease to keep the high pressure turbo from exceeding 23 psi because the low pressure turbo is feeding the high pressure turbo with 20 psi air at this point and the ECU will open the wastegate all the way to try to stop the boost from increasing. This in effect just bypassed the high pressure turbo.
4. at 4000 rpms the low pressure (big ass GT35) is now supplying air at 25 psi and the poppet valve is overcome and the high pressure (GTX) turbo wastegate is full open, so the GTX is just free wheeling at this point and the GT35 is spooled and flowing 400 g/s of tire burning beauty.

Hey! I've got one of those! ppump 12V cummins, but no intercooler?

Eric, just from the experience I have on the diesel side of things and doing compounds:
Go with a little bit bigger A/R than you would usually go with for the low pressure.
And get yourself an external wastegate to bypass the exhaust side of the high pressure turbo.
To actuate the wastegate, use a valve that pushes drive pressure again boost with a regulator, so you can aim for a 1:1 ratio of drive to boost. This keeps the EGT's down and helps for a smooth transition between the turbo's.

Another thing that I am going to try on my truck in the next year or so is a spool valve. You should look into this. They are pretty sweet! They divide the T3 foot (assuming that is what you are using) with a butterfly valve, and then once you hit enough boost, it opens it back to a full T3, so it ups the velocity of the exhaust air at lower RPM's.

Another thing I have been working on is a Max32 chipkit and the code to operate a VGT. Basically I am writing a ECU to operate a garret VGT off of a 6.0L Powerstroke with inputs from drive pressure, throttle position, and rpm's. I could pass that onto you if you have any interest at using a VGT for the low pressure. And if you source a GT3788VA Turbo (the 6.0L turbo), just make sure you watch a youtube video on cleaning them before install. You can also have them sent out to get a milled for a little bit bigger billet wheel.

My setup is in the works right now. Nothing too great as of yet, but I have helped friends on sizes, fabbing piping, and tuning (they have deeper pockets and different priorities[:D]). I just picked up a 47re auto trans that can reliably handle 1200rwhp. Over $9k worth of trans... I also just finished my motorcycle two days ago, so I am going to rebuild my savings a bit before buying some new turbo's. I am planning on picking up a steedspeed T4 manifold, spoolvalve, and billet BW S464 with a low A/R in the not so far future, but I wont get the 80mm low pressure for a while.

Anyways, so no engine bay pictures for now, but here is the other day right before I replaced my tires:

And here is a picture of my buddy John's truck. Same everything as mine, but he threw on a 24v head, and has a setup that put down 866rwhp and this year will probably break 1000rwhp. 10s 1/4's
He get's me to spend money on my truck when I dont want to. lol

I was reading about the twin supra and diesels and figured it would great in our cars too.

[CorneliusRox]

I was reading about the twin supra and diesels and figured it would great in our cars too.

There are guys breaking into the triples for diesels now. Some to go for over 2000rwhp, and some for only 600-700rwhp but very quick spool and low EGT's.

You can make a budget set of twins by using and OEM high pressure, and any bigger one for low pressure. The high pressure gets all the work and low pressure has a cake walk since (rule of thumb) it only uses about 80% of it's potential.

Others make triple setups with two oem turbos supplying one larger turbo for a slightly laggier that stock setup, but next to no loss on the low pressure.

Then there is the three stage where you better have a very high end high pressure, close in size mid pressure (still decent quality), and slightly bigger low pressure for a super smooth very large powerband.



I wouldnt mine a 600-700rwhp triple setup for crazy low EGT's and broad power.

I would love to help out the best I can. Sequential Turbos is not something we have typically done before, but any assistance that we could possibly provide, I am here to help! [up]

You mention needing help on plumbing, what kind of help are you looking for? We are a company that is interested in furthering platforms over making a profit, and love to help out whenever we can.

For the plumbing, it will be hard to describe without a mockup or drawing. Till then the best I have is a description I have in my head.

The first part that I am spending the most time thinking about right now is the custom down pipe. It will need to be more like a manifold. First bend will connect the turbine outlet of the GTX to the turbine inlet on the GT35. The next is the actual downpipe from the exhaust of the GT35 to the car exhaust. There is barely enough room to get both these parts through the area behind the GTX, so I am thinking they will have to be joined into a one piece manifold, and maybe even made into an oval welded section.

The next part of the plumbing that is going to cause some headaches is the inlet joiner. Let me see if I can get some sort of drawings put together and post them up, or maybe find a good example picture. The picture posted above of the Diesel setup is almost exactly like what I am going to do, except the turbo positions are switched with the lo pressure up top and high pressure down low.

A GT35 flows over 60 lbm/min, so with 22% losses and good tuning you should be around 450-500 awhp! That with the spool up of the GTX2863, umm, umm goodness! I am going to put the 2.0L emblem back on the car just to see people's jaws drop. Twins FTW.

This is why we love you! Another thing you could do is talk to a shop about a custom manifold setup. It would be more expensive, but if you could run it with equal length piping it would make the spools quicker which may be useful. Plus if it was a sequential top mounted setup it would be super easy to work on and sexy as hell!!!

I was planning on running an holset turbo with a custom mani, but I might talk to my local shop about the possibility of setting something like this up since the holset wouldn't spool till around 4500 :)

Edit: Just read the rest of the post lol. can't wait to see what JHM and you put together in a drawing. I'd definitely be down for a GB if this went all the way and became a valid option. That is if I have the patience to not do it myself lol.

Edit: Just read the rest of the post lol. can't wait to see what JHM and you put together in a drawing. I'd definitely be down for a GB if this went all the way and became a valid option. That is if I have the patience to not do it myself lol.

Thank you; I appreciate the enthusiasm. I have been planning it out for a week now, and I think I have the general layout down. I need to find time to draw it up, but it should fit nicely and look mean as fuk.

Basically, you would have to go over/under with the turbos to get them to fit. So you couldn't make them both top mount, instead a bottom mount high pressure turbo would sit tight to the engine. Then the low pressure turbo will be mounted top and to the side where the stock airbox fits.

The thing that was stumping me for the last couple of days what where to route the intake and air filter. Last night while staring at my engine compartment in the middle of the night it hit me, move the battery to the trunk and place a cone filter where the battery sits. Cut a hole in the firewall for the inlet pipe, and bammm! The complete package will fit piping from the cone filter through the fire wall and into the GT35 with the GT35 mounted skewed at 30 degrees from the axis of the car, and with the turbine clocked about 45 along the axis of the turbo. So the turbine inlet is aiming approximately at the cylinder #2 coil pack. This will aim the turbine exhaust back to the downpipe area. Now the inlet will run from the battery compartment area, through the hole in the fire wall, over the turbine, and pull a 180 into the low pressure turbo compressor which faces 30 degrees off axis (towards the passenger headlight). The compressor outlet of the low pressure turbo is clocked 90 degrees from the turbine inlet, so when the turbine inlet is aimed at the #2 coil pack, the compressor outlet is pointing at the radiator area in front of the high pressure turbo inlet (which is nicely connected by a 120 degree silicone elbow)!!

Lol you're pretty excited about that. It sounds like a great idea, but it also sounds like a lot of shit going on in the engine bay. Plus cutting the firewall would cut out some others that would be potentially interested in the setup I would think. You don't think that a stubby filter (the circular done shaped ones) on the turbo inlet would work, instead of having all that piping running around?

I'm still thinking that it may be possible to have them both top mounted sitting where the intake area is, you would just need a properly designed header that curves down into the cavity where the stock turbo sits and comes up and pushes the smaller turbo closer to the front, then have the larger turbo cantered sitting right behind where the passenger headlight is. Although, I'm not sure how much piping would be needed to properly set up the bypass valves and such that that could be the limiting factor to that setup. Plus this method would need another downpipe instead of the possibility of using the stock one.

Either way there's a nice chunk of room there to use and plenty of options. It's gonna be sick no matter how it goes!! :D

[$nooze]

I don't like reading threads like this cause I begin to think that living at home is okay as long as i have a car like this

[peb]

I am planning out my longer term build right now and want to retain the option of building up to this.

On that note, would an er dsmic provide sufficient cooling for a sequential turbo setup down the road?

Also, what about hpfp options. I'm leaning toward the hpfpupgrade stage 1 pump for now. Will that be an adequate fueling choice down the road? If not, can a stage 2 pump be easily tuned down via maestro to run on a single smaller turbo? (I'm thinking Frankenturbo once out since the tuning for it seems like it is going to be safe with stock rods, and will supposedly out perform a k04/k0r)

Edit: I would do rods and other needed engine mods before going bigger than just the ft. I'm trying to map out a build plan that I can grow into, getting gains as I go without a lot of wasted $, and only upgrade each individual thing (eg intercooler, hpfp) once.

I would think that the ER DSMIC would be able to supply the cooling needed, but personally I'm gonna try and find a front mount that takes up as much space as possible, I'll probably even cut the center portion of my crash bar out to do so.

I'm running the KMD hpfp right now with no troubles, I was running a K0r turbo but I had to change back to my K03. but yes you can tune down fuel output to meet the goals you want to achieve with a stock turbo.

[ericpaulyoung]

I love my ER DSMIC. It is funny, but if you check the specs they are larger than almost all the FMIC out there, and they fit stealth. I've had them for over a year and had nothing but good results.

However, I am running out of things to modify on my engine and I have never tried a FMIC. So I am thinking to sell them and buy the ER FMIC in black so that it is still stealth but would make for a good weekend project. I may have addition problems to modding :/

epy

EDIT - as for fueling, I think the twins will require a fifth injector and likely a surge tank. I don't know for sure, but the low pressure turbo that I am looking at can reasonably flow over 60 lbm/min, which is roughly speaking 600 crank hp (roughly that is). However, the fifth injector does not run off of the high pressure fuel pump (it is port injection) so the stage I pump should be fine as it will only need to supply the direct injectors.

[ericpaulyoung]

OK, I am officially starting to sell parts and buying equipment for the sequential setup.

I found a supplier in Germany that can send me the new bypass valve (rev.C version) for $220 US shipped to my door! So that bad boy is on order and should be here in 3-4 weeks (slow shipping is the downside).

I decided to go smaller on the higher pressure turbo, so I am selling my GTX2863R. If anyone is interested, the thing comes from ATP with the turbine housing for $1540 and I am selling it for $950 plus shipping :) Only has about 10k miles on it and is in perfect shape, so if you are planning to go BT now is a chance to get a good deal on a turbo. It comes with the internally wastegated T25 turbine manifold.

As for what I am going for, well I am planning on running a GT2560R as the high pressure turbo. The thing should spool plenty quick and hand off duty to the big boy, which I am still undecided as to what to use. In the running right now is a GT3582, GTX3582, and a GT40.

God this thing looks small now :/

[Charles.waite]

You should totally get 2 red T emblems from '06 A4s

Red Ts will add too much power though...

[canadianA4B7]

Wow another step forward, always enjoy yer ideas EPY. Id be in on somethin like this to be a first in ontario canada to build something this rare! You mentioned doing a 2.7T swap somewhere, and ive got a 2.7T motor myself now w sigle setups and bi turbo setups ive considered that route, but this is just going to a completly new level.

Will you need to bulk up the oem block? Strengthen or something? Im assuming all other internals will need replacement. And how high will this rev? Will the trans take this power,? The front axles and rear diff? Im not doubting just curious.

And turbo for sale including manifold? And maybe some future help with maestro? Lol well when you arent wrenching!

[aluthman]

hehe, yup! I do wish that I got the "stock" location kit from ATP now, as it moves the turbo forward like 4", and that would give me a lot more room to run the exhaust connection from the first turbo to the second, and then another exhaust back to the downpipe. With the kit I have, it is going to be a really tight fit. Thinking I may have to have the two exhaust pipes welded together. Also considering flexible connections between the first and second turbo so that you can actually put the sequential turbo onto any other BT kit by simply removing the airbox, and adding in the sequential turbo as a "kit". That should make it easier for people to copy my design for themselves. Then we would truly have another "Stage" after going BT. I am thinking:

Stage 1 - tune
Stage 2 - upgraded fueling and air management (intake, exhaust, etc.)
Stage 3 - upgraded first turbo (K04, GTX, EFR)
Stage 4 - adding second sequential turbo

- EPY

I think this will legit qualify as Stage 5.

Smart choice going a bit smaller. I presume you're getting a stock location manifold to give you a bit more space?

Wont tuning the 5th injector be tricky with the variable pressure low pressure side? Or will it just require a lot of logging and tweaking to get right?

[ericpaulyoung]

Check this out. An exhaust piece from the Chevy Cobalt should work perfect to turn the 5-bolt exhaust of the GT2560 directly to where the big turbo will sit! So I think that tight bend at the high pressure turbo location may be solved with a stock part :)

http://i1073.photobucket.com/albums/w381/ericpaulyoung/ATP-COB-008_450-2_zps7865740a.jpg

[ericpaulyoung]

The 5 bolt exhaust is at the yellow line, with the fifth bolt facing the engine. The outlet to the cast piece would then face the location indicated with a red E. The opening would face the direction of the E. So right at the location of the E, I would have to make a T piece that connected from the outlet of the Tial 38mm bypass valve and the outlet of the GT2560.

Looks pretty slick. Are you just going to weld a new flange on the Cobalt piece for the LP turbo?

[ericpaulyoung]

Looks pretty slick. Are you just going to weld a new flange on the Cobalt piece for the LP turbo?

yup!! Should be pretty slick actually. I'll run the high pressure turbo outlet and bypass valve outlet together at that new piece that I weld on. then the down pipe will look almost exactly like what a top mount normally looks like. Now on to figuring out the inlet piping :)

Hey, somebody buy my GTX and get some ponies! I need to order my miniature and tiny GT2560!! :) It is going to look pitiful with just the little guy on there until I get the tuning done for down low and then cut in the big boy.

I am aiming for the first in town drivable 600 crank hp 2.0 FSI :) Ordering parts as we speak. My twin disk clutch gets order this next paycheck from INA engineering, the biTDI bypass valve is ordered Monday, and I will order the GT2560 as soon as someone buys my GTX. Then I need to order the above mentioned Chevy Cobalt exhaust bend, TIAL 38mm wastegate, and some piping. If all it good, I could have a working sequential in 4 months!

If it doesn't work, I will have a barely drivable crap box, but if it does work it'll be the cat's meow.

epy so what else did you do to yer engine for this gtx? Ive read yer build thread a dozen times as well as everyone elses. Just wondering if my K04 setup would handle the gtx... Id post up the k04 asap and pick up yer gtx if i played my cards right when i did my motor for the k04.

[ericpaulyoung]

All you need is a general engine build that includes rods. I overbuilt my engine quite a bit, and if I did it again I would save myself some money and just do pistons and rods along with fresh machining. If you are interested, let me know and I will not list it for sale and put your name on it for when you are ready. But you will have to commit to buy it within 30 days so that I don't stall my sequential build. If you need the manifold and engine mount, I will give you those at 65% of original cost also. However I would recommend just calling ATP and getting a stock location manifold. That is a cleaner install and you can reuse some of your lines off the K04.

epy

[ericpaulyoung]

Note, you will need a 3" V band downpipe, as the BT kits come with V band connections. I will say they are 100% better than the bolted connections though. I will always use V band connections in my future builds.

Or the other option is I can hook you up with the whole tamale, and you just bolt it on and download my tune and hold on :)

[canadianA4B7]

ok so the rods aren't enough then. I wanted to machine the head when I had it apart but there was numerous ppl who claimed it wasn't worth it for a K04 build. so id likely have to redo the top end? pistons, valves springs retainers or is the OEM stuff gonna be ok?? and as for the all the stuff you've got that you would include PM me a price please. if I have to rebuild the engine again that would really be shitty. im assuming I should have done it all the first time the engine was torn apart.

[ericpaulyoung]

Nah dude. Rods are enough. I refreshed the head, but nothing more. In other words, I didn't do anything to the head to make it perform better, just stuffed new parts in it even though I didn't have to. You are all good for pretty much anything this side of 500 hp as long as you don't try to hit 7500 rpm's or more.

Edit: never mind. I just saw that pic of your garage. I hate you sir.

Did you notice the boat storage to the right of the house? The owners before use went through a crisp diverse and didn't take care of it the last two years, so it needs some repairs, but the place has so much potential! Got it for a great deal though.

epy

[Charles.waite]

Only thing to do with a boat storage area is to put a boat there. Might want to add "buy a boat" to the schedule this weekend...

House looks awesome too. That garage is freaking spacious! I only have street parking. And now that my new neighbor insists on parking across the street from their house, on my side, I have to park on the other side. It's weird though. They entire street parks on my side if the street. Except me. Because of the aforementioned issue and because my trees overhang the street and drop all sorts of shit all over my car every day. So I'd taken to parking across the street. Which makes me sound stupid for complaining, but I don't want someone else parking in front of MY house. At least my across the street neighbor has a driveway and a 2c ar garage so he doesn't need the street parking.

Update.

1. New revision C of the bi-turbo bypass valve ordered this morning from the Father Land! Should be here in 3-4 weeks.

2. Working with CanadianA4B7 to get him into a GTX kit for a great deal, so I can fund the next step in the sequential build.

3. Changed the plan for the big turbo. I was going with a GT35, but after looking at the maps, a GT3076R-WG will have better overlap and still push an easy 500 hp. Most importantly, it has a smaller body and will take up less space.

meanwhile, i'm saving up for coils almost 2 years after buying my b7. git it, gurl.

Awesome. Excited to see your initial pics of setting it up. Ill hopefully be doing something similar next summer once I'm done building my second engine for this setup. Although with different turbos due to hopefully increasing the rev limiter one I'm done.

You planning on using the hep 4 port injection intake mani or getting one fabbed to solve any fuel problems you may run into? And also what kind of control setup you thinking for the extra injectors if you go that route?

[ericpaulyoung]

That would be great! I really hope more people try this after I am done, and I think it a way to get the 2.0 FSI to play with the other big boys out there. The RX-7 setup has a sequential, and so do some Supras. It is definitely a way to squeeze more out of less. I am still aiming low with the low pressure turbo, as I think I will start hitting limits on other parts of the car. I started looking at GT35 and GT40 sized turbos for the low pressure side, and quickly moved away from them. The 2.0 FSI just isn't going to be reliable at 700 - 800 hp levels. Plus getting the maps to overlap between the high pressure and low pressure turbos is more difficult. Then again, you have to remember our little four banger engines really start to suffer at high rpms, and as you go past 7k rpms you really start punishing the thing. As such, I will likely never raise my rev limit past the 7200 that it is at now.

To tell you the truth, I am starting simple on the fueling and only going to add complexity as I need to. The first thing I will test is how far the methanol injection can take me. I figure I can get pretty high just shooting 300-400 ml of 80% methanol as I get to higher mass air flows. If I run lean, then I will add a surge tank and 5th injector. Probably never go to the HEP manifold. They look awesome, but for my goals this time around I can likely do the same for a lot less by just placing a 5th injector after the throttle plate.

As for control, I will run everything for now off of a progressive controller reading my MAF sensor.

Yeah these are all good points. However I think with the upcoming release of P and P heads from integrated engineering and apr, as well as cams getting cheaper and doing the proper supporting mods to the valve train we could reliably push 8500 rpms. Which would really open up the range for bigger turbos to come into play. Such as a gt45, hz40, or precision 6765. Pair that with a gtx 28 or 30, built short block, meth and figure out the fueling and I think we could hit much higher numbers with the sequential setup. The only problem would be tuning in my eyes.

That's a good decision. I was planning on doing that, but I decided it's smarter to get a second engine, set a goal, and take my time getting there without having to take my car down all the time. Then if something goes wrong swap the old back in, fix the problem, and swap again :-)

I've read that the HPFP starts to float around 8000rpm. Sure you could put a stiffer spring on it, but that would exacerbate the CF issue even further.

IE has pushed the 2.0t to well over 500AWHP, however, they did that by ditching DI and using port injection, so yea, its really more of a stroker 1.8t...


I've read that the HPFP starts to float around 8000rpm. Sure you could put a stiffer spring on it, but that would exacerbate the CF issue even further.

I really don't understand the reasoning for the FSI HPFP setup. They should have done a design thats direct driven off the cam (basically how the Vacuum pump is setup) like BMW does in the Mini. Their N54 HPFPs are basically the same design as ours and they have similar issues as we do. Such a dumb design...

(I think I have my BMW info correct, but I might be a bit off, feel free to correct me...)

You should talk to Tyler@IE (nein-reis) though, hes a really good guy and might be able to help you out some, at the very least point out some weak points and things to address you might not have thought of.. He came through in the clutch when my HPFP bit the dust.

And if are plans work out i think ontario will see one extremely quick B7 A4! Thats 4x4 ride height! Lol this setup is gonna be amazing! Id be interested in a GTX 2863 biturbo setup on my ar..... It seems like that could be a future adventure i might have to take on! Or maybe EPY ill ship you my 2.7 and a nice line of credit and you can do something crazy with that motor! Keep up the work!

[ericpaulyoung]

I have had many good conversations with IE, but they have went wrong on components and specs for my build that cost me quite a bit of time and money (wrong timing chain, wrong thickness valve shims, wrong specs on tower bolts that ended up breaking, sent me the wrong thrust washers for my crank, etc.) To be fare it wasn't Tyler I was dealing with, but that is a lot of errors on just 1 motor. Mostly they were quality control issues, but it was a lot of errors. So now I just do my own research and take everyone's opinion with a grain of salt. /rant

And if are plans work out i think ontario will see one extremely quick B7 A4! Thats 4x4 ride height! Lol this setup is gonna be amazing! Id be interested in a GTX 2863 biturbo setup on my ar..... It seems like that could be a future adventure i might have to take on! Or maybe EPY ill ship you my 2.7 and a nice line of credit and you can do something crazy with that motor! Keep up the work!

I will build it for you :)

[Charles.waite]

I have had many good conversations with IE, but they have went wrong on components and specs for my build that cost me quite a bit of time and money (wrong timing chain, wrong thickness valve shims, wrong specs on tower bolts that ended up breaking, sent me the wrong thrust washers for my crank, etc.) To be fare it wasn't Tyler I was dealing with, but that is a lot of errors on just 1 motor. Mostly they were quality control issues, but it was a lot of errors. So now I just do my own research and take everyone's opinion with a grain of salt. /rant

Interesting. That sucks. I didn't realize that.

Ah, no biggy. It was a learning experience and I still think they are a great shop. They just need to install some quality control checks, and I am sure they will only get better and better. They are producing good things, and obviously they have some money backing them. Maybe the Mormon church :) Or daddy's bank account? Not sure, and don't really care as long as they make good products for us [cool]

Damn, if only i could construct a graph of a latest pull of my k04. Im not hitting 25psi im hitting 22psi, and i think usually peak around 2700-3500 i did a lil run out on some niagara in the lake country roads and im hitting peak way more then i thought. I guess i lied about when i reach peak. As i thought it was more like 3500rpm but i was wrong sorry for missleading post.. Hummmm lets make 3 members extremely happy this week! Someone purchase the s3 ko4, enhancing there life to an awesome oem turbo first inspired by epy himself, ill throw down the gtx into a canadian B7 and EPY can fly his car to the moon with some jet packs or whatever else he decides to throw into his A4!!!!

[shiro1745]

Eric you are moving fast, awesome work. You surprise me as always!!

Pm your price for the gtx kit. I may make myself an early Christmas present if the price fits my budget and keep up the good work.

No way! :) CanadianA4B7 has dibs on on the kit first, but I will PM you a price and you can have sloppy seconds if he falls through. I am literally unbolting the whole kit and removing the custom motor mount so that who ever buys it can simply install the whole thing! :) Bolt on power baby!

[kloeb2]

Someone buy the canadians k04 so he can get the gtxxx!

I can attest to the fact that it spools like a beast and can hit at least 25 psi at 3000rpm

Also, to ease some weary minds out there, I have the same turbo and I have a stock head and only IE rods on the bottom end. Not a single engine problem yet. I've run tunes at 30 psi, 28 psi, and now 26 psi.

[drumnjuny]

yeah the motor build especially head will just enable you to romp on it around a track or an extended amount of time sans fear.

[shiro1745]

Eric let me know exactly what i need to know about your kit, if any issues, any modifications I would need to do(I hope none) and let's get this deal moving. When do you need the money?

I promised I would let CanadianA4B7 have first bite at it, so let's see what he is able to pull off. I would like to have the money and the kit off my car in the next 3 weeks.

As for the kit, it will be complete with everything except new gaskets. You will literally just pull the old turbo, lines, downpipe, and motor mount off and install the thing complete. I was thinking about piecing it out and keeping some of the lines and stuff to reuse, but that would just make it harder for whoever buys it from me. So I am making it literally a bolt on kit with everything you need. I could do the swap in about 4-6 hours myself.

to be honest I kind of wish you could get the funds in time cause I really don't need this turbo, I should be ok with my K0r once I have it running properly, but I'm like a spoiled kid, I just want it. I did the same with the new CBR600 I got, I had my SV650 and it was more than fine but I saw my friend's R6 one day and a few days later I bought the CBR [:D]
And I wouldn't be afraid to buy this from Eric since he's a stand up guy. It would be a win win situation, me helping him get the cash quick and him helping me get a great deal.

You should really try to sell the SMIC on ebay since there's shops that look for parts over there and those are things that brake on a front collision. They go expensive, I have a set for sale but I didn't post it yet, if you want you can try selling yours since I'm in no rush. I sold my old set of SMIC for I think around 400$ on ebay about a year ago. Actually you should really try to sell all of them on ebay, I really think you'll get more money and sell faster, I always look in the classified here and things don't sell quick, if they do, they sell really cheap.

good luck on selling the parts!!!

For those of you that are interested in what the T25 sequentially setup with the GT3076R is capable of, well here is the combined map.

The T25 map is in thin black lines down low, so it is hard to see, but if I get the transition smooth, I can run 70% efficiency or better right up to 5500 rpms, and still push up into 7k with out much problem.

If it is creating positive pressure at idle then I doubt it can hold 23 psi, we're probably thinking of a spike around 18-19psi, also why did you change your plan and go with a 3076? why not 3576? and gtx3576 :)

on the other hand why not build a supercharger, then you really will have significant positive pressure instantly, and you can compound with a 30 or 35 series turbo?

It will never reach 18 psi, the little T25 will only build and hold 10-15 psi, and I plan on setting it with a manual boost controller to 12 psi. It will compound with the bigger turbo in the overlap region and be free wheeling by 3500 rpm's. it is only to get me from 1000-2500 by itself.

EPY

[ericpaulyoung]

Basically it results in a GT3076 build with zero lag.

Eric

[aluthman]

When does the 3076 start making boost? Will it be able to take over by the time the T25 is free wheeling? I'm assuming some overlap is needed for a smooth transition.

No Motorsports Engineering is a bit more involved than automotive engineering, from the course description, it's specifically geared toward racing, specifically NASCAR, Indy, and F1 but I'm sure it would be beneficial to other forms and circuits.

[vvenom800tt]

Well my dreams are in F1 and motorsports engineering gears towards racing, not being a mechanic. Which ive had my fair share of doing in the Army.

[kloeb2]

Im in the same boat, Hopefully motorsports engineering at Purdue, we shall see.

Do they have any automotive masters programs? I feel somewhat unfulfilled with just a ME bachelors degree.

Well I am not too sure about my choices, as I think my combination of the T25 and the GT3076 maps looked a little better, but we will just have to see in the end.

Looking at the GT2560, it spools a little later (based on the map) then the T25, but it reaches a few psi higher and has good overlap. hmm, still should be good spool.

Looking at the GT3582R though, I think I might have gone too big for the little 2.0 Liter with that guy. I cannot move the air needed, and it looks like I will have to run 30 or 33 psi to hit my goals of >500 chp.

I just started searching, but does anybody have experience with a GT35 on a 2 liter?


Here is the GT2560 paired with the GT3582

Have you considered a gtx3076 or 3576?

[ericpaulyoung]

Have you considered a gtx3076 or 3576?

The 3076 was my first choice, but I got a good deal on a 3582, and figured might as well try it out. It doesn't look "too" bad, but it is a big turbo for a 2 liter. I can upgrade to a GTX3582r later on and go higher pressure, but I don't know. The two turbos should interact a bit and even help each other out, so maybe it will be better than it looks. Just don't know.


How do you like the GTX35 on your car? Do you have any dynos or videos (I will go search also).

[ericpaulyoung]

The GTX3576 and GT3582 have similar compressor maps, so I may be able to garner some good information from you on your build.

No dyno yet, only chance I had I spun on the rollers and something happen to some sensors or some crap. Times been limited so haven't been back.

What kind of vids you looking for?

Honestly? I love this turbo

Any spool up videos, or general driving videos to see the transient response would be great. Can you also give me a general "butt dyno" impression as to when you reach 10 psi of boost, and any description of the power band?

Thanks,
epy

I'll be fixing this tomorrow or Wed, I'll grab a vid then. Even with this it shockingly pulls really well. Lol

A gt35 pulls pretty well?? Understatement of the century!

[ericpaulyoung]

Do you know the specs?

[CorneliusRox]

10psi at 1000rpm? I like where your head is at. At that rate, you could lower your compression more, still have great spool, pull more timing, and have a stronger top end. I would recommend looking into garrets VGT's though so that you can see exactly where the best point to set idle is. You dont want to spool exactly at idle, and you could also set it up to engine brake like crazy by closing the VGT considerably when your foot is off the throttle, you're in gear, and above a certain rpm.

Would be if I didn't have a 1/4" slice in my charge hose

It's clearly noticeable by 2psi, spool is slower but I've cranked up the bc so it still hits 30, just takes longer to get there. Lol

It's part of the kit I run, I don't know the exact company who molded it.

RS4 injectors fo sho! Look at that cloud of smoke!

[ericpaulyoung]

I believe that is Chris' car from 1552. Here is a picture of the bay figment of the big boy. This is exactly where I was hoping to place mine, so this is super news that they have already got it to fit over at 1552.

[tankdeer]

Chris at 1552 drives a stage 1 avant. Unless there are two Chris's

[ericpaulyoung]

Your right, I think it is Shawn's car. My bad.

Jsandor!! welcome to the club haha. i wanna see that dyno!

also did i hear it cutting out at the end? almost sounded like it was misfiring??

[ericpaulyoung]

If you read the thread or ask about the car, it is a mystery, but it was never finished and was sold for parts ???? Seriously weird. Sounds like someone racked up a bill and forgot to pay :/

I think they had different intake manifolds and one had a precision intercooler and the other Garrett other then that everything was the same

[ericpaulyoung]

Mother ******s stole my Geo last night at my new house. Nice welcome to the neighborhood. I put the Audi up and started taking it apart, and pulled the Geo out front to go to work, and this morning I walk out and it was stolen.


So my build plans will have to slow down till I find another second car.

[ericpaulyoung]

I am a bit pissed right now. Can't get to work, have to put the Audi back together, waiting for the cops, ... Well the neighborhood looked nice but obviously there are some questionables lurking.

Well the cop said they find cars about 90% of the time, so hopefully I hear back soon.

That freaking sucks!

I bet it was the best looking Geo on the block
