5 axial pp on the head. Way back when apr was in motorsports they offered this for their 2.0t big turbo program and picked up a reported 70hp. I copied the idea and was hoping for maybe half that with the k04. I had so much money in that engine and car build i dont recall the exact price as i had also had the block balanced but id guess around 1200

Thank you,

Oz

im getting a power surge if I do a pull from 3rd or 4th (usually). The RPMs will smoothly bounce up and down a bit and then continue normally again. You can hear it through the exhaust as well.

I have an Auto Trans (6-Speed) 2009 A4 Avant with the JHM K04-R and APR v 3.1 file loaded.

Anyone have any ideas?

It sounds like compressor surge or oscillation but if you post some data logs, we can get a better idea of what’s going on.

[steviesteves]

Is anyone here currently running REVO Stage 3?

Very curious too,I heard it’s supposed to be a lot more mild and power concerned than apr.

It has done this before, I think it was when I went stage 2 but I'm not sure what resolved it before. Could it be the ecu still getting used to the K04?

A video is worthless to determine what issues you may have. You need to log data to find out what’s wrong. APR mobile with dongle or VCDS is a good investment.

Those n54 335 cars hold their value super well. An 08 or 09 is worth more than our newer A4s. I wouldnt mind picking one up at a decent price as a project car. I need to start looking into their reliability. I know they have a few issues, but they can easily get to like 600hp.

So after some modification I was able to get the Miltek Downpipe to bolt up again to the CTS Turbo. For those of you who say the Downpipe doesn't add power I would have to disagree. My 0-60 was consistently 4.10-4.15. With the Downpipe I've hit 3.96-4.03 in less than great temperatures.

You modified the downpipe to bolt up to your CTS Turbo testpipe?

I'm a little confused by this too.

The CTS test pipe bolts up to the OEM downpipe. The Milltek downpipe is an OEM replacement. It shouldn't need any modifications to fit.

[muffinman92]

Yeah, originally the flex pipe was rubbing the transmission mount, so i had that section cut and flipped around. I have about 4mm worth of space now lol

The downpipe barely has space on the allroads, and the CTS downpipe changes the angle ever so slightly causing it to rest on the transmission mount. If you look at pics of the two the Miltek has a different curvature and size to it compared to OEM. They both bolt up but mainly due to the flex pipe.

Ah ok, that makes sense. You Allroad guys are always causing manufacturing problems [>_<]

I got you. I basically flipped that section where the flex pipe was. You can see the new welds. Also, I shortened it and had the reducer welded on. It was shortened to accommodate the space for the ECS exhaust cut out.

Guys - i don't want to start a new thread and I thought that this thread would be the perfect place to ask - since all you guys worked with your turbocharger.
On the 2.0 TFSI, how can I check the 'play' or 'tolerance' of the turbine with as low effort as possible? I got access from above nd under so thats not the problem - I just need some tips. IHI OEM Turbocharger. Thanks !!

[A4 Centaur]

You could hook a vacuum source to the actuator if you have one. Or you can try and wiggle it from below. Listen for a rattling sound when you decelerate near a concrete wall.

I could get mine to move due to the pressure exerted by the actuator. Some have had luck disconnecting it and putting jam nuts on the rod to make adjustments.

Bkr8eix

-4.5 on that first log is too much for me but still less than -5cf isn’t bad. But these are basically a stock sized turbo with an OTC tune. You should be seeing 0cf across the pull with the right set up. I’ll try to do a pull but I’ve never logged any timing retard on mine with bkr8eix, R8 packs and a TR11 on either 93 or e85. Stock plugs / stock heat / stock gap not the best idea. I did some tests and swapped to range 7s last winter. Went from having 0cf on 8s to up to -3.5 on the 7s. 3.5 is still small... but that still a little bit of power on the table

But probs on posting actual data. That’s helpful stuff

lol, well i'll admit that messing with spark plugs can be 9 parts voodoo and 1 part reality not unlike going down the rabbit hole of choosing the "best oil" but my thinking was this.

The FR5DTC is a multi ground that are side mounted and its a copper plug. Best of all worlds. What made me think of it is that it is similar to a plug Porsche uses in the 911. I'm sure the F5dp0r is also an great plug with a great history behind it and its worth a shot but is is platinum and single electrode side firing so I just choose to try out the fr5dtc first.

Honestly i havent really had issue with the stock plugs so there may be no appreciable different in any of these cases but worth a shot... keeps me from buying multi thousand dollar parts for now ;)

yeah I got you. The porsche ones appear to be a big copper center electrode but i'm told they have a platinum coating on them to make them last longer. They do go 30K real world miles and look new when you take them out usually.


With the A4, they appear to be straight up copper but since its only 4 plugs and they are right there up on top I figured its so easy to change them this is the perfect application to try them out. Replacing them every 10K miles would be too easy and in reality if I run octane boosters sometimes like on a lap day i'd probably change the plugs out afterwards as they get orange mmt deposits on them.

Man I wished we had 93 octane or E85 here at the pumps. The only ethanol sold here is E98 from the race crowd, it’s hard to find and it cost $6 a gallon. Any side affects using Lucas octane booster?

Some tuners achieve HP with boost and some do it with timing. My tuner has the boost cranked up but I only achieve 12° of timing advance with zero retard. I suppose if my boost tapered to just 18 PSI at redline he could give me a more aggressive timing map but I am limited to the 91 octane gasoline here.

What’s better, 3° more timing advance up top or 3 PSI more boost? Take your pick.

[bhvrdr]

My current boost request at redline is 1.39b to 1.4bar from 5700rpm to redline and prior to that its in the 1.45 to 1.5 bar range. My turbo only makes about 1.28bar pressure by redline though likely due to the DA. There may be possible restriction as well. I'm still looking into it.

I was able to hit 19.5 degrees on these fr5dtc plugs but generally i'd call them pretty much the same performing as stock plugs.

I did feel slightly smoother delivery under those high load, low rpm bogging engine speeds. Its probably just a factor of having old OEM plugs in there though.


It would be cool to have access to e85. We dont have much at all in our area. One station only and its in a crap neighborhood and its a Racetrack so i'm not going there. Given the results so far I have no doubt I could hit 22 to 24 degrees on some real knock suppression stuff like e60 or up or some 104 race gas.

Yes....resting on the radiator support...going to try and twist it a little to eek out some clearance but the tolerance is unacceptable. Need to have gaps between all of the hard pipes within their silicon connections.

The trouble I’ve had has been on the passenger side. Occasionally I have to readjust so the hard pipe from the TMD doesn’t touch the support underneath it. I haven’t had issues on the other side, meaning the driver side. Not sure which you’re referring to as the outlet; outlet of the IC or outlet of the turbo. I’m concerned it will end up like the cts issue @shonseb had, and have considered giving it a nice little dent for some extra clearance.

Per the instructions for your IC, isn’t support piece supposed to sit behind the crash bar? And not over it?

ECS amazes me sometimes, and not in a good way. You should see my billet dipstick, yeah it was the revised one that they claim sits below their cf engine cover. That’s doubtful to me, because a corner completely wore away from rubbing on my hood. Thankfully it ate the hood pad first and then rub on an interior support, so you’d never know from the outside.

[awdconnor]

Yes....resting on the radiator support...going to try and twist it a little to eek out some clearance but the tolerance is unacceptable. Need to have gaps between all of the hard pipes within their silicon connections.

This is the coupler I’m using. I believe because we can’t use the tmd, this 1.75-2.5 only allows the pipe to go in so far, so there’s probably about an inch or so of room that it could go up.
I’m starting to believe that it’s not the pipe making the noise and it’s something else. It’s quite annoying.

I’ll try to get a video of it for reference soon.

Is that the noise pipe?

Its the pipe that connects the turbo, to the intercooler.

[Fastbke170]

I had same problem with my eurocode hard pipe clearing off the turbo. During install we took a mini sledge to the radiator support bracket and dimpled a flat spot so it would clear. Upon inspection a few months later it was rubbing so I just removed it.

Why not just wrap the support in some rubber hose like heater hose or whatever?

I ask bc i'm probably adding them on in the coming months.

If I want to know the total amount of timing from my tune should I log:
Camshaft adjustment intake bank 1: actual value?

Or Ignition timing timing adjustment cylinder 1?

Do this. I put some sound deadening material around my crash bar where I thought my Tr8 could vibrate and cause annoying sounds. I had some dynamat type stuff laying around and just taped it on there. With the ecs piping and intercooler I'm not having any vibrations though.Best of luck!

So haven't posted in a awhile, was having some oil leaking from the bell housing. Had the trans pulled assuming it was most likely rear main seal. Turned out the block had a hairline crack inside of the bell housing.
Bought a salvaged motor from a 13' allroad with 40k on it. Had all my parts swapped on the "new" motor and she's pulling like a train again. My block had 80k mi on it when it "failed".

Ya'll are gonna wanna punch me in the throat for this one but I decided to dick around with a ebay F23L until I decide whether or not im selling this car or not. Got one for $650 which is supposed to be from the same manufacturer that Doug Harper uses at frankenturbo which some slightly different components. Frankenturbo uses a 625 Alloy Steel Mixed flow turbine rotor, this ebay job is showing a 713C Iconel full back turbine rotor. Franken lists a 2618 Billet alloy aluminum compressor wheel where the ebay job is using 7075 series billet aluminum.

I'm gonna pull it apart when I get it and check it out and see if it offers a cheaper alternative to any of the options we have in the hybrid turbos. All evidence seems to suggest that alot of the hybrid turbos are also chinese turbos as well, just with better quality control. If I can find the source for them I think we may have a turbo at half the price that could be just as reliable, assuming its balanced well and the seals dont shit the bed after a couple thousand miles. Worst case scenario im gonna send it right back, they offer a 1 year warranty and 30 day return policy no questions asked.

A Chinese made (of unknown origin), EBay sold turbocharger? Hmm. Installing my K04 was a major pain in the ass. I’d hate to have to do it more than once....

So the F23 frankenturbo is made/sold by WUXIEY Turbocharger Co. LTD. I was able to locate a supplier supposedly selling from the same company which should be the exact same part being sold under the typical chinese intellectual property theft practice that they normally conduct for a fraction of the price. You can contact the suppliers directly through alibaba but you run into the issue of negotiating for either a larger order, or having to deal with negotiating freight prices, so I decided to go with the slightly more expensive ebay option which had them already here in the USA ready for shipping. This practice has been around for quite a while actually, 10 years ago we found the supplier for Skunk2 cams selling them on alibaba and you could order the same product that was selling for $1200 a set for $35 dollars a cam through the supplier, you just had to order 1000 of them. lol I am hesitant to put it on the car, I bought it for more dissection and see whats going on more then anything and then I may decide to use it or not depending on whether or not I feel its actually safe. Gonna take measurements of the wheels and see how they stack up against the real frankenturbo.

Here's another big question, has anyone ever tried using a different matching CHRA that potentially fits in the exhaust/compressor housing of the K04 for the B7? I found CHRA's from Mamba that come in a couple different styles....

I suspect that frankenturbo's 10 blade mixed flow turbine and 62.4mm exducer billet compressor wheel is just the design being played around with to achieve a certain power result. It seems like the CHRA's are all the same dimensions and the housings are modified for the specific VW/Audi application from the factory, this would make sense given the varying combos of hybrid turbos out there. Part's being readily available from chinese suppliers for these, you could assemble your own "custom" K04 hybrid turbo and sell it under your own brand name and only pay in the hundreds for each turbo and resell for in the thousands.

[Spawne32]

If I could find the compressor housing bare bones, we could assemble these turbo's ourselves for half the price of what they charge with better components. lol I've only been able to locate the exhaust side for the K04-064 for the S3, which would technically work but I need a matching compressor side for longitudinal applications.

[Jezza]

Just machine the K03 compressor housing to fit the k04 wheel. That's all the compressor housings on these k04s really are. Or, you could modify the original housings so that the inlet and outlet works for a longitudinal application.

Is that all they are? Machined K03 housings? Because I cannot find an OEM k04 that comes in this application at all. I dont even know how I would machine it. Sucks cus I found an adjustable wastegate actuator as well that can be used in this same application. https://shop.mambatek.com/Turbo-Wastegate-Actuator-AUDI-A4-A6-EA888-Gen-1-K03-087-K03-106-023-0200.htm

Looks like your right, looks like all the JHM turbo is "Re-profiled or "bored out", aluminum compressor housing with tighter wheel clearance. " which is a bitch because I don't know where I'd get a K03 housing bored out and how much it would cost. Could negate the savings I was hoping I would find here. My only hope rests in buying the fully assembled "ebay" turbo and seeing if it will accept a S3 CHRA. I bought the 7+7 compressor wheel with the 9 blade turbine and gonna see how it compares size wise to what the ebay turbo comes with. Also not to sure about the exhaust housings as well. One seems to have a shrouded turbine wheel with a larger overall flange, which seems to match up with B7 housings, the other seems to resemble more of a frankenturbo style with an unshrouded outlet.

Why replace the whole chra? It might be sufficient replace the bearings and seals with genuine parts and having the turbine and compressor rebalanced.

[Spawne32]

Cheaper if you consider the cost of the custom 7+7/9 blade wheels, cost of the oem rebuild kit, and rebalancing. whole chra comes balanced with oem seals and bearings.

[Jezza]

Why replace all of that anyway? Just send it off to have the balance checked and run it. Lol. Mid-west turbo will balance the turbine and compressor for $55.00. If it really is the same manufacturerer then I can't imagine the bearings or seals are any different.

That's what I'm going to look at when I get it, mid west wouldnt take the entire turbo, they want just the wheels and the thrust section, not the CHRA. I contacted a local company about balancing here as well to see if they will take the CHRA if I remove it.

[Spawne32]

your gonna laugh but i sent these specifications off to about a half dozen chinese suppliers for quotes, i have one offering me the full turbo assembled with OEM components (so they claim) thats balanced before assembly for 379 dollars shipped. lol I requested full specifications regarding the wheel sizes on compressor and turbine side and the materials they are using.

Do you have the part number for a genuine K04 that fits the longitudinal application? Besides the CTS turbo which is the only one I know that genuine.

I think that is the point though, its not worth more then a honda civic to me, or anyone else. Dumping thousands into some "premium" turbo kit that I full well know the company only paid 1/16th of what they sell them for isnt what I am all about. Plus, as I have said, many times before, you cannot make the argument that OEM (borg warner or IHI) in this instance, or any other OEM component for that matter, is any better then the supposedly "cheap shit". OEM turbo on my car was replaced at 65k for a bad wastegate, along with many others, some at even lower mileage, and guess what, my K03 or JH5, whatever it may be, is on its last leg again, along with the trans, engine, and a whole host of other parts that will not get replaced with OEM stuff either.

Let's see what happens with this, im roughly $1200 deep right now between the ebay turbo and performance K04 CHRA from the S3. If it works, and it puts down similar or better numbers then any of the other offerings, and lasts even half the time the OEM one lasted, I think it was worth it to me.

[A4 Centaur]

^ Yea I think my Avant was 54k? in 2012 bucks. For the money I have put in her, I could have....but I love the Avant more than most things I could have or already have. Not the Ducati though. She's a special creature in her own right as well.

The cts and the unitronic is a genuine k04 for transverse that is slightly modified with welding to the cold side to make fit. Ive had both btw.

You can see unitronic does very little modification to the housing. They instead focus on using their own hose design to the mate up to the stock location intercooler hose. Then Unitronic mives one of the exhaust housing studs to allow any oem style cat, testpipe, hfc etc to mate up on that side.

Cts welds qite a bit into the cold side to mate up to the stock ic hose location. Then you use their testpipe or hfc.

Anyone could do these modifications...

So that's how much of a profit margin there is on those two kits, CTS being $2400 dollars, and Unitronic being $2999.99. You can get that K04 for $1650 genuine from mamba, whos probably STILL making a good profit on it as is. You just need to either have a welder or the ability to make an adapter piece for the outlet. I think the stock specifications on those are...

I find the unitronic kit to be a decent deal. For $2999 you get the genuine turbo that is modded to fit oem location, some nice completely custom hoses that allow you to run the modified location bpv, and completely dialed in programming with technical support to make anything right. I literally installed my turbo in a day and was dialed in running perfect logs on the first run. Theres alot to be said for that.

The only other way id do it us just buy the fake k04 from china for 600 and the apr tune for $1049 fully loaded. Still that could be more headache than its worth.

For me the cts kit doesn't make sense. Id need to spend 2400 for the turbo and 1049 for apr software.

For the jhm and hpa it makes zero sense since youre overpaying by 1000 for the turbo.

[Spawne32]

Tuning seems to be the biggest issue here, even with having eurodyne, im not confident his K04 or F23 tunes are anything but crap. I'm squeezing 22psi out of the K03 right now using his F23 base file, and I've managed to dial it in quite well, but out of the box it was total crap even on the stage 1 and stage 2. His stage 1 files were running 10.5:1 AFR's at WOT, car was puking black smoke out of the back of it, and the lambda tables are SET THIS WAY!! So yeh, I can agree with you on that you pay for a good quality tune. This is all experimentation right now, it may turn out to be nothing and I may wind up having to send everything back. I have 30 days for the return period if I don't want the parts, so we will know one way or another.

Speaking of installation of the new turbo, what would you say was the most difficult part doing it yourself?

Alot of people spend too much time on the midpipe to downpipe because you're pretty much guaranteed to snap the little studs and have to drill them out. I decided to avoid that hassle and just buy this 200 midpipe...

https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F14 2898184194

The othe pita was getting the turbo out with the cat attached. I should have done that with the car in service position. But i couldnt wiggle it out without the car in service position so i had to disconnect the cat from the turbo. I found the last bolt behind the turbo to be a major pita.

I think nect time ill just disconnect midpioe from downpipe and go service position and slide the turbo forward then out with cat attached

[Spawne32]

lol so basically everything ive already done, im curious, since we have the same bad dog motorsports downpipe, did yours rub right at the first bend under the car? I had to....modify....mine with a sledge hammer a bit to give it some clearance, the bend was not tight enough and everytime i went around left turns, the 3mm of clearance it had at rest was not enough to keep it from vibrating the tunnel.

Haha yeah every once in a great while under just the right turning with the car on an unlevel ground ill get a sound from it probably rubbing. It looked like it may be an issue when i was installing it. I dont drive the car alot and im still keeping my distance from it after the turbo install but ill probably do a little "shaping" of it soon too.

Yea, those banjo bolts were a pain getting threaded. My exhaust bolts/studs weren’t a problem. I had only 30k miles on the odometer so things were not too frozen on.

btw, I bought my CTS K04 (and HFC) from a forum member here in the classified section. He bought it brand new but wrecked his car before installing the turbo. I got it still in the original box for $1500. My tune was just a $50 upgrade since I already had their Stage 2.

Yea, those banjo bolts were a pain getting threaded. My exhaust bolts/studs weren’t a problem. I had only 30k miles on the odometer so things were not too frozen on.

btw, I bought my CTS K04 (and HFC) from a forum member here in the classified section. He bought it brand new but wrecked his car before installing the turbo. I got it still in the original box for $1500. My tune was just a $50 upgrade since I already had their Stage 2.

$50 to go from Stage 2 to K04 tune wise is awesome! Wish it was like that for all tuners!

Connecting the coolant lines from beneath the car. PITA.

Nothing better than dealing with a stripped triple square when trying to replace the oil return line...and of course it just so happens to be the last bolt needing to come off...🤬❗️

Ebay turbo is here, looks like a 6+6 compressor, 12 blade full back turbine wheel. OEM turbo gasket fits the exhaust side perfectly with no modifications needed, gonna take some measurements of the outlet. The electronics it come with are probably junk, the N75 valve it came with was broken right out of the box, nipple broke right off of it. Not sure how these sizes match up, still looking into that. The CHRA spins very roughly, like its binding on something internally, not sure if its because its a journal bearing or what, never had a journal bearing turbo do this.

I think the mambatek CHRA from the S3 is the correct one for this housing, trying to get some finer measurements. Mamba is listing the one I purchased to replace this ebay center housing as "7+7 2618 performance billet wheel, Inducer OD: 46.39mm, Exducer OD: 56.08mm (Extended tip OD: 59.66 mm) Nose: 10.97mm" I think I am measuring right inbetween the actual exducer and the extended tip on that wheel which is giving me funky measurements. Gonna try to pin this down better.

[Spawne32]

Exducer looks to be somewhere around 57.6mm and tip to tip on the blades seems to be about 60.9mm.

[Spawne32]

Inducer is measuring almost identical to mamba specs.. mamba listing Inducer OD : 46.39 mm, and since this is the part that actually goes into the bore of the compressor housing, seems it should work.

[Spawne32]

So mambatek thus far has ignored my emails and messages I have sent over facebook, even though they read them, regarding the order status and the lack of confirmation despite them billing my credit card the day of. Not sure how thats going to go thus far, I may wind up having to file a charge back for both the CHRA and the wastegate. I decided in the meantime to order a OE replacement K04 CHRA from TRL (Turbo Rebuild Limited) over in the UK. They sell melett aftermarket VSR balanced OE replacement CHRA's. £164.50 (euros) shipped to the US, roughly 221 bucks I think. https://www.turborebuild.co.uk/webshop/prod_4238940-KKK-K04-Turbocharger-CHRA-Cartridge-53047100518-Turbo-Core-53049700064-K040064-53049700191.html

This OE replacement CHRA should be exactly what I pulled from the ebay turbo mm for mm unless there is a discrepancy in the ebay turbos wheel design. If I use this CHRA, total price of the build for a legit K04 internal turbo comes to roughly 875 or so minus the upgraded adjustable wastegate and using the one it came with. Also totally up in the air should I get both CHRA's to choose from, which set of wheels I want to use, the 7+7/9 blade mamba, which is supposed to have huge flow potential, or the OE K04 sized wheels which are 6+6 and 12 blade on the turbine.

[Spawne32]

Few more updates, got a hold of mambatek tonight. Apparently their CHRA's are built to order and their production line is backed up at least a month right now, so they gave me the option to cancel that order, which I am going to do. Going to go with the OE replacement CHRA for the K04-0064 which is the S3 (8P) turbo which I believe is what you all are considering "true" K04's. Should have that CHRA in about 10 days, soon as it comes in ill get it all built with some new grade 10.9 hardware I ordered from mcmaster carr, along with an improved vibration resistant locknut for the vband it came with because I didn't trust the one it had.

Hi all- somewhat related but also a bit off topic. I’ve been trying out various oils in my Allroad and S4. gotten very nerdy with data and UOA reports from blackstone haha. I’ve run 8100 xcess 5-40 in my Allroad it’s entire life and it’s been. Cams looked amazing at 110k when I took a look. Also no consumption ever. Tried Redline 5-40 and honestly it is just too damn thick at operating temp. Car felt bogged down and i lost a few mpg. Tossed some 300v 5w-40 in, and holy hell. Gained back the mpg and the car feels rev happy as hell. My oil temps also decreased over 10f at 90mph. I kept thinking it was all in my head but I kept noticing how eager it felt. The double Esther race oil shizzz seems to be no joke. It’s also 0% shear to 392f which is higher than our motors will every produce. You can order it on FCP and have lifetime replacement. It’s $35 per 2L can (very expensive) but FCP replaces it free when you send the old stuff back lol. Thought I’d share. I’m a true believer in many things being snake oil but it feels like Motul 300v is not one of them. I’ll post a UOA after like 4-5k Miles. Seems like a good fit for a toasty K04 motor that gets “driven”

Keep in mind that stuff is going to have very little ad pack so its meant to be run at race intervals. Youre going to probably want to get it changed at least every 3k miles. Youd usually want a strret oil with detergents if running it on the strret.

The additive pack is actually very dense (as far as anti wear additives like moly and zddp). It does have some detergents but not as many as something like Amsoil DEO or another oil meant to go 15k. As long as you aren’t running it in a diesel motor or have a fuel dilution problem, it should not be an issue. The additive pack in 300v is very good for wear but could shorten the life of anybody with cats still (no issue here). there’s a lot of UOAs for people running it well beyond 5k and the reports are stellar. tbn retention is excellent. I think some crazy dude ran it for 14k miles on some forum and it came out better than his M1 0w-40 did. I’ll be doing 3-5k swaps like I always have.... especially now that FCP swaps it free

Anyways back to K04s! Just sharing! Carry on

People will advise against using any non API Sn oil for street use for a variety of reasons... usually catalytic converters / emissions protection. If my UOA comes out iffy or something odd then I’ll be sure to post it. Motul 300v is also Esther so the high polarity makes it stick to shit haha. Kinda neat the engineering that goes into something “simple” like oil. If people are dead set on long intervals then Amsoil 0w-40 signature or Motul 8100 xcess is your best move from the countless hours of pointless research I’ve been doing lol.

got the new K04 core in from the UK today, and let me tell you, its like a night and day difference between the ebay core and this melett core. Thing spins almost as freely as a ball bearing turbo. Comes complete VSR balanced as well. Gonna try to fit it in the ebay turbo housings and see how it does. If it matches up right I think this will work out well.

Yea that’s totally fine. I’d probably be fine running M1 0-40 in the Allroad if I did 3k intervals but I drive really hard sometimes and the stated 10k interval for that oil wouldn’t work out for me. It would probably retain its TBN just fine but heating it in the 250-260 Range (at the sensor) a couple times is enough to shear it to a 30w from some of the UOAs apparently. It’s supposedly why BMW LL-01 or whatever the newest one is doesn’t have M1 0-40 on its list. Those 335s and 340s run hot as hell in normal driving.... but for how incredibly cheap M1 0-40 is, there’s no reason to not keep it really fresh anyways.

The more you dig into VW 502 and Porsche A40, and bmw LL-01 certifications the more you find out it’s less of a performance spec and way more of a business arrangement. Not surprising I guess.

The birds nest sound will go away, that sound comes from the way the compressor is designed. As far as the turbo sounds, the K04 still gives them, as will any turbo producing high boost.

The 5th injector was added to support the additional fuel volume required by ethanol’s stoichiometry.

Its just the price that changes.... if you run an APR k04 they reduce the cost of the tune for you, if it is another turbo they make you pay full price.... (Atleast that is how it works in CO)

I’m running a PTP one that I got off someone here in the classifieds. Keep a fire extinguisher handy for the first test drive, all the smoke will freak you out.

Thanks ill look into it.

Also, has anyone went from APR to another tune? what needs to be done since APR locks the ECU?

[muffinman92]

This is the one I am running

How difficult is it to fit the blanket with the turbo installed?

Was this a custom tune with logs and iterations, or a one flash deal?

Looking forward to your results!

I believe he installed an eBay K04 and he drove it to IE’s shop in SLC for a dyno tune.

Do you think they're releasing before spring 2019. This is only reason I haven't installed my K04 yet because I'm waiting on their tune.

I was the K04 Beta 9 months ago. Your tune is probably based off of my file ;-)

[B1GW3AV3R]

If anyone wants a good K04 option I still highly recommend HPA's k04, I've been running it for about a year now without a single issue on APR's software running 93 I'm 6mt. Looking to do meth next and run 100 oct and then take her to the track and hopefully run some mid 12's. This has been a perfect blend of power and also a good daily for me.

[dapeople]

i am in the market for a K04 and looking towards the HPA kit, thanks for the 1year update and that you are still recomending this turbo. quick question, although this is not popular to do and im sure i wont be getting the full potential out of the turbo i wanted to see if anyone has installed a K04 (doesnt matter what brand) with the stock donp pipe?
the reason i want to do this is bc in Chicago, IL i have to pay $600 every two years to get APR or any other tuner to mess with the car so it passes emissions.

You’re the Hawaii guy I’ve heard about. So did this car get any mapping done in Utah at elevation? I’m also assuming you don’t have an e85 compatible model as they don’t yet have a file available.

APR charges you that much? With UM the flashes or reflashes are FREE for the original buyer as well as any updates. If I have to go in for service, I just get charged by my tuner shop $85 for their time, but that involves a flash back to stock and reflash back to stage 2+

[A4x]

You wouldn't get charged each time for the price of the tune. You would only get charged whatever the shop wants for the few minutes it takes to flash the car. A lot of people are able to pass OBD emissions testing with APR software and running K04, I know I did.

My K04 file was written by IE’s lead engineer in SLC using their B8 A4. My vehicle was never in Utah. I emailed him numerous data logs to get my file dialed in for sea level.

Although my vehicle is flex-fuel compatible, E85 is not sold at the pumps in Hawaii so I was not interested in an E85 file.

[A4x]

So you passed emissions without going into stock mode?

I did use program switching to go back into stock mode. However I'm not sure this is needed. I have the same condition as bb-tt above, I noticed that all my readiness is passed in 93 octane mode as well.

I believe my file and several others on here were based on Perry's. Quite honestly have to thank Perry for taking the plunge and getting all the kinks worked out. The beta version tunes they have sent me have ran flawlessy. The car is my daily driver and it is perfectly suited to normal driving but has a smile factor when you want to drive like a moron or for that matter make a moron wonder why he just got left behind by station wagon.

Who is running the stock downpipe with K04? I am considering to put the stock downpipe back in to eliminate some drone I picked up with a Magnaflow muffler in place of the OEM muffler. I don't want to add any noticeable restriction or turbo lag. Here is a cutaway view of the downpipe resonator:

The stock cat/dp is the most restrictive part of the setup. Have you thought about swapping the magnaflow for a stock S4 exhaust?

Yes, some peopke may not know that the IE performance exhaust removes the first resonator. Some folks that do the S4 conversion remove the 2nd resonator. I just wanted to clarify that i have a hfc + 2nd resonator + s4 exhaust

I took the liberty and put your latest log into a couple of charts. Besides the two spikes in boost between 3500-4000 RPM, you boost looks very good. You hold 20 psi up to 6300 RPM and ~18 PSI all the way to 7000 RPM.

I'm using an EC 3 inch test pipe, to a CTS 3 inch non res downpipe to an S4 exhaust. No drone.

Any hesitation to accompany that overboost and MAF drop @ 3800 RPM?

So you are running the S4 center resonator and dual rear mufflers only? This is similar to my exhaust setup before I put the Magnaflow on, and there was very little drone (downpipe resonator was removed). I bet the stock A4 center resonator and rear muffler are extremely similar to the S4 cans. It was once I cut off the rear muffler I get some drone.

IGNORE GREEN AND RED CIRCLES IN DIAGRAM BELOW. Diagram is only to show the basic layout of an S4 stock exhaust.

Yeah I'm running the S4 exhaust from the red circle (in the diagram) back. Sounds really good with the test pipe and non res downpipe.

[A4 Centaur]

I placed a Vibrant Resonator in the middle just after the first one. Killed most of the drone from 2200-2500 RPM's

[A4x]

I placed a Vibrant Resonator in the middle just after the first one. Killed most of the drone from 2200-2500 RPM's

This is also what I'm considering but I figure it is cheaper and less of a hack job if I throw the stock downpipe back on. I will try this, and if it's too quiet then maybe I'll chop my Borla downpipe in half and put a vibrant in the middle. It just seems to me that the straight thru vibrant cans will not dampen any of the long wavelength drone sounds. The factory small resonator is quite good for reflecting longer wavelength sound and cancelling them out.

My exhaust was pretty perfect with HFC, Borla straight thru downpipe res delete, stock large resonator, and stock muffler. Eventually I tried to make it louder by putting a Magnaflow in place of the rear muffler but now I'm paying the price with drone. It seems most of my drone is at idle and up to 1800 rpm.

The stock rear muffler seems to be a complicated chambered setup that actually splits the flow right off the bat, probably as an attempt to cancel low frequency drone among other reasons:

Really wasn't that bad. I agree having a tool for the coolant line would help, but I was able to use a socket allen and an open ended wrench to tighten the coolant line to the turbo.. Having an aftermarket cat already in play really helps with the whole equation as well. Otherwise, if you can follow directions, this is a do it yourself-er

So I found half of my notes, the most important thing is going to be having the t55 torx for the cooling lines an Allen wrench fits also can't remember what size, if you could find a t55 Apex bit that would be Ideal. You are going to need a Dremel or something to cut the brackets off the cooling lines. If you have a gfb diverter you will need one longer bolt can't remember the size to bolt on to the adapter that keeps the dv in the stock location. Also in mine I could not get the cooling line to line up with the lower port (kept wanting to crossthread) so I moved the plug from the top port to the lower port. Then the coolant leaked as the cooling line went directly over the sealing plug for the lower port and kept it from correctly seating. I solved by using two crush washers under the cooling line supposedly the kit comes with 1 thicker crush washer, I did not notice and was not taking everything back apart to find so for less than a dollar bought a couple stock crush washers at the Audi dealer. Everything else was pretty straight forward, you can download the install directions although when I did they had not updated them for keeping the dv in stock location. If I remember anything else I will let you know. Oh if you have the eurocode turbo muffler delete with the larger outlet you will need to get a stock size hose from there to the intercooler inlet. Speaking of which I need to post a bunch of parts in the classifieds.

Your test pipe/any HFC should have the same mount points onto the turbo. The only "issue" I've heard is that the hole closest to the engine, up top, needs to be opened a little more on your pipe.

Had to have the shop re-clock mine, and the silicone inlet is still butted up tight against the top of the motor. Didn’t run into any issues with oil feed though. It appears the CTS kits are a “pay for what you get” when compared to APR’s plug and play system.

Has anyone ran into any install issues with the cts K04 with the revised DV location? The shop cannot seem to get the oil feed to reach even after the modification to the oil line.116210

Mine fit fine with no issues.

[makisupa]

So I went down to the shop and the issue seems to be more that it wont reach because they cannot fish the oil line by the outlet. There isn't enough space to get it thru. It also seems like my K04 has a few more bends than others I have seen. Anyone have any pics to compare? 116275


The space I'm referring to is between the outlet and the DV. They also tried to relocate the line around the DV, but when you screw it into the block it kinks the line so no go.

It appears they didn’t provide you with the correct kit, definitely not the same bends.

The bends in yours look different from mine. Yours seems to be a longer straight tube with a 90⁰ elbow. Hmm manufacturing issue?

I did not see your comment above @comfy pursuit, my bad. I do agree with you something is fishy.

Hopefully your shop gives you a break on hours.. nothing CTS provides fits without some adjustment. My intake (kohlefaser luft-technik intake system) no longer fit and had to go with a CTS intake which needed cutting/manipulation to seat properly, while my CTS downpipe needed cutting and re-welding to sit properly as well.

I went all CTS based on their recommendation for ease of installation, which was a bag of jokes. I’m overall happy, just not a typical bolt-on accessory as it was implied.

If you read my earlier post in this thread i had issue with the coolant line. had to move plug to lower port run line to top port. I had to use two crush washers so it would clear the plug but supposedly one of the crush washers supplied is thicker. It did not mention it in the instructions and i did not notice and was not tearing it back apart to find the thicker washer. I have been running that way since October and it has worked fine with no leaks. Oil line fit fine for me. If you have GFB dv+ you will need one longer bolt than the ones supplied with the kit.

[makisupa]

I did read that and made a note of that. Thanks for the tip. I finally spoke to CTS today and the outlet is not the proper one. They admitted it and are sending me the correct kit ASAP. we will see how the rest of this works out. I went with all CTS components: K04, HFC, and downpipe.

I'm on the fence about upgrading the DV. Now obviously would be the time seeing it's out, but I previously upgraded on my B5 and saw little return. Granted that wasn't an upgraded turbo....

Two weeks post-K04 install I did GFB DV+ due to improper throttle response. It resolved most of the issue, but still believe some is present due to APR K04 file. Debating on IE map and guinea pigging for K04 at elevation

My game plan is APR mapping due to the availability of e85 around my way. If I do upgrade the DV it will be a GFB DV+

So my Allroad is in the shop getting a new engine as well as the APR K04 installed. I was running the ECS Tuning Luft-Technik intercooler on the stock K03. The shop tells me the intercooler does not match up with the new K04. I looked on ECS' website and it says the same thing..."For use with factory K03 turbocharger. Most K04 turbochargers do not have a removable turbo muffler in order to install the included delete". Has anyone been able to get this intercooler to work, or do I need to purchase a new intercooler yet again?

A simple silicone adapter to change the size from the turbo outlet to the ECS intercooler pipes should do the trick. Do you have the hard pipes? I don't know the diameters off the top of my head.

These guys should have what you need:
