Turbo options (no K04's) ??

[awedio]

Hello All,

I haven't been on these pages for a few years so pardon by "noobness".

What's the latest & greatest in turbochargers & injectors (not interested in K04's)?
Wasn't there some self-lubricating/grease turbo that was pretty good?

Can anyone point me to a page or area?

TIA

EFR’s seem to be the latest, greatest thing right now but nobody really can use them to their true potential. That’s my observation at least.

S3 injectors seem to be the gold standard still but there are rumblings of a new and better injector for these cars coming out soon. Forget by who.

Do you mean the Nostrum Energy ones?

It all has to do with the tuning. Arnold at Pag Parts has tuned my setup, and it runs well. Im sure it could be dialed in further make more power, but at 26psi it is fun to drive.

Custom tuning is probably the best route to take, absolutely. Finding someone good is the hard part.

Agreed. Its the only option on anything other than a K04, literally.

These are already available but you need to make a harness. Not too hard of a job to do but awaiting a manufacturers solution might be abettet plan I’ve done the harness myself and it’s one thing I wouldn’t suggest many take on unless your confident in your soldering/harness making skill.

And at $451/injector it’s pretty tough to justify the expense at this point. $$2000 for injectors in a maybe $5000 car.... and the S3 have been very good to us over the years. I’ve also dabbled with the RS3/rs4 multi tip units and if I can get the 4.0T guys to supply some data I could likely get these running in our cars. Now these won’t be as robust as the nostrum units but are said to be 16% more flow then our S3 units.

If your interested in some different turbo options search outside of North America. Bigger things happen all the time over in the UK. Much more info there and using more widespread selections of turbos.

Ok, so the EFR line from Borg Warner.
Men, that shows you how long I've been out of the game...Garrett's used to be the hot ticket!!

What makes the Nostrum Energy injectors so special?

Custom tuning is probably the least of my worries.

How are the Nostrum injectors performing in your car?

Would you be willing to share info on your harness plans in exchange for a 'lil beer $$?

EFR turbo in that kit?

It is a TD05H-20G variant

Not sure that would work for me since I have a custom manifold!

They’re massive. And they should be pretty easy to get working on our cars. Franks a man of his word and has done some serious reseach. He and I spoke last year about some data I had provided he investigated and then took it to the limit. Not exactly sure how much larger but they’ll likely fuel 2 motors w only 4 injectors.

And im not running them at this time. Nostrum I believe have them running in 2 TSI cars at this time. That’s how I understood the last emails.

As for a harness I’m an electrician. Anyone can be an electrician you just have to complete 5 years or so of training. Nothing I can just hand over. Slightly risky on my part.

I’ve run 2 Garrett’s and now I’m into a EFR myself. Some different turbo characteristics for sure. Garrett’s are great 2863 and 2867 both very snappy turbos both will hold 26 psi + and with their billet compressors they do put down some power. EFR 6758 is in the car now work still in progress cause I cannot just leave shit alone. This things large it feels and there’s a bit of lag or maybe it’s the currrent maps, but it does back a serious bunch of punch when I get into some throttle. Then there’s the TD series units out there they are strong in the JDM world lots of subies, mitsu and others use them as they are a bit snappy themselves. I’d think this is on par w the GTX 2863 or slightly larger from the claims of the low end and maps it’s larger. Look into this deeply as the tunes available on market are incomplete and no updates provided in years. Then you can get into things like Panman142 5557, or some of the 62 series units they use over in the UK making 700 +hp.

What manifold? Arnold PAG PARTS in NY is super knowledgeable on turbos. He’s manufactured a number of custom manifolds I own one myself. If you have something like an Indy 6758 hotside and need it fabricated to fit another manifold arnold at Pag parts is very capable of this task. His welds are very precise and the finish inside edges had zero lips or any type of edges. Very high quality product from their shop. Super knowledgeable.

I agree. I'm tuned to 20psi on my EFR and make good power. I'm dropping off the spare block next week to have pistons/rods installed and hopefully by summer have it turned up more.

I assume Frank is from Nostrum?

Why did you make a harness if you aren't running the injectors?

Twin scroll - EFR 6258 vs 6758 vs 7163: which one & why?

Let me see if I can dig up a pic of my manifold.

He built it to run the Gen 2 RS4 injectors from the B8.5, from what I recall.

Haven’t finished with the project yet. The RS4 gen 2 continental injectors that frank (yes from nostrum energy) test seem to have cut out on him at 100bar. This is an unknown item which I’m trying to sort through but information is lacking. I recently posted into the c7 section inquiring for datalogs from the 4.0T engine platform. We need to know the fuel rail pressures from the 4.0T and a few other detailed items in order to figure out why frank saw the cut. They were showing to be more flow right from the start then the S3 units many of us use. He had also tested a set of Chevy injectors which would require head work and likely another harness to use them (again I believe 2 members here tuned with UM are running them but no info is provided from seller or users)


Here’s the graph nostrum put together light green is S3, Red is the Chevy units, then the failed at 100 bar continentials (which is yes higher then both at the beginning if this can be sorted this is for me a $200 upgrade), then franks custom units. Fitting the gen 2 units is easy as they fit without much other then harness.

From past user of these Gen 2 units they were successful run I believe tuned by revlimit tuning in Greece. Reached out to them about 400x and they are just really terrible at responding. Makes sense when your to busy building 600 hp+ projects. If they could just feed me the info we need then done deal I start running them and provide what data is needed. I will say this though the car did start and run for about 5 seconds on these injectors. James was there when it ran. Then being I thought they were the problem and with a bit of a heads up from frank I removed and went back to S3 injectors. So we need data then we have another option. If someone speaks fluent Greek you would be a huge help here!

[awedio]

Are the Nostrum units not worth pursuing seeing how much they can flow?

Or is the hassle of building a harness not worth it?

It sounds like unless you are building a track monster, like 1/4 mile or something similar then they may not be worth it just due to cost alone. Injectors fail from time to time and $400+ per injector is a lot of money to throw away. The S3’s are a great injector and he RS4’s are even cheaper than the S3’s if you can get a tuner to take the time to map them in correctly.

@canadianA4B7 What happened to this: https://www.audizine.com/forum/showt...1#post12378573

[canadianA4B7]

Yes started ran then codes so I pulled them out went back to S3 units. I’m looking for data logs from 4.0T owners to see rail pressures. With that data it’s assumed the current driving them could be turned up the maps I was assuming needed were for minimum on time for these, and 2 other maps maestro had added then deleted then never added back for me. Though nostrum tested them they failed at 100 bar at what driving signal he used I do not recall it may be in old emails. If someone could call revlimit and ask them what current they are running them at, the firing angle used and min injector on time that info is necessary. With that I can send info to both nostrum and to my tuner and I could drop them back in. I’d also toss in a few more bits with this as always.

[awedio]

If I'm understanding all this correctly...

The RS4 Gen2, look like they should work (aka have potential), but are failing.
This is an ideal injector since it's pretty much plug-n-play (no harness needed)

The Nostrum units are great (as seen in the graph)
Cost is an issue vs the RS4 Gen 2
This is not plug-n-play since harness & other mods will be needed

[canadianA4B7]

RS4 Gen 2 are made by continental and require custom made harness. Same harness would be required with nostrum injectors.

Plug and play would be S3 and similar years RS4 both have same harness plug in as oem.

Audi Fuel Injector - Genuine VW Audi 079906036N/079906036AC (A8 Quattro, R8, RS5, RS7, S6, S7, S8)

What is the cost of the Gen 2 injector vs Nostrum injector?

Who is a reliable source/supplier for the Gen2's?

[awedio]

I emailed Frank at Nostrum.
He has some great news/info.

I'll let him respond here.

[Der Typ]

Hey guys,

unsure if you are still looking for some data, but I came across some info.
The FPRV on the 4.0T breaks open at 145 bar. So that is higher than the standard EA113 valve.

I am also still curious about better injectors. I kinda can't believe the Nostrum test. Doesn't really make sense that the RS4 gen2 injectors would drop off so early.
