DPJ's GTRS Eliminator Install and Development

Hi Marts!
Just waiting for a big mofo Jetex to turn up. Also hoping to get the water/methanol running tonight.
a new bumper belive it when i see it and also if so someone had better get round there and take that holesaw and jigsaw off of him.. lol
Nice Thread I've read it a few times as me and a mate of mine have been wondering about this type of conversion on a Audi S3 using the ATP Quattro K04 version.
I was wondering if I could ask you about the inlet transition.
You appear (from the thread) to have had issues in this area and opted for a step down piece of silicone to resolve the issue., which gives you a lip before the turbo compressor.
Is there any reason why you didn't opt for ATP's big bore Inlet so that you transition from TIP to inlet size was reduced. This to me seems like a good solution as you would then need to look for an 80mm to 76mm straight reducer which are easier to get hold of.
Here's the big inlet I'm referring to.

Good point!
The reason I didn't use it was
(a) the problem of getting hold of one
(b) m0rk had pointed out that there was no real advantage as it still went down to the same diameter at the compressor wheel (slight step) showing.
Having said that, once I've got rid of the oval big bore, I would be tempted to try one to see if there was any difference.

So if we were to go ahead this it would probably be the easiest route but not the best for optimum performance, but better than DPJ Mk1 inlet.
What would you do differently if you had to do it again.

Well I need to finish turbo inlet Mk2 first, but
I went for the eliminator setup because
a) my K03S was shagged and a GTRS Eliminator came up, complete with bigbore inlet.
b) I already had an ATP manifold fitted.
c) I understood it would fit directly to my downpipe.
If I had to do it again,
I wouldn't bother with the eliminator kit because the turbine housing for the K03S replacement is a bit of a compromise. (The replacement for the K04 is better). I'd have gone for a normal GT28RS, fitted to an equal length manifold with a custom made downpipe.
This would have saved me a huge amount of time sorting the inlet side. The downside would be the manifold, but I need one now anyway. The cost of getting a car trailered to a fabricator for a DP is not a major cost compared to other outlay.

Fantastically good advise there!
I'm fairly sure that the big bore inlet does make a significant difference, but can't remember where I saw figures.
There's a Scottish guy (ChrisS3) who has a GTRS on an S3, he is a member on here somewhere (but I don't know how often he comes in). I know he didn't do the fitting himself, I think Star did it, and I know that he wanted conservative mapping, but he was still doing 320 odd at the clutch, I think.
I think he hangs about on audi-sport.
Depnding on what your mate wants, have you seen what figures someone has got from an "Imolavirus" K04 Hybrid?

We know of ChrisS3 of on AudiSport and he has chatted about the conversion. But as Jim did the conversion were unsure of the issue's he had along the way.
Only thing we did know is there were issues.
Rob Don seemed to suggest on Jonah's big turbo thread that the TIP position isn't an issue with the S3/TT but we have no way to confirm this.
We need pics to be sure or maybe just speak to Jim.
@ Feel : We've been doing quite a bit of reading about hybrid K04's Cartec's K04R the K04-024 and the Imolavirus.
Bang for buck the eliminator is looking the way forward.
Strange that Jacob has gone AWOL. Apparently with quite a few customers turbo's as well.

For the inlet to clear the shifter cables, the turbo would need to be sitting about 50mm + higher than on LC. I just can't see how...............
On ETKA, the exhaust manifolds look the same.

I had to speak to Jim about my map on the Audi so it gave me the opportunity to ask about the fitment on a S3.
He said the Eliminator K04 is a doddle on a S3. He's done 3 already. No fitment issues and said he could do them in his sleep.
I asked about the gear linkage issues associated with the K03 manifold and 6-speed gearbox, he said "I Know what you mean and have since stopped installing the eliminators turbo kits because of it".
He has also said that the position of the turbo is such that it's higher than the linkage and any 3" tip would suffice.
Think we have our answer.
I also asked about the LCR fitment he said that he hadn't done it but assumes that it's the same manifold in the same position so he doesn't see why it won't work also.

Yes, on thinking about it, the shaft on a KO4 sits higher than a KO3S shaft because the K03S turbine housing is more 'underslung'. The respective eliminators will be the same. That's the difference.
Heres a question tho, if you could get a k04 downpipe would it be easier and get more power if you went for a GTRS k04 eliminator version.
I know you'd stil have to fab a downpipe but fitment issues of the inlet and whole normal fitment issues of a proper GT28RS wouldnt be there.
I'm just thinking that Hooch had a k04 fitted to his Ibiza with no fitment/room issues.

remember chaps that the K04-02* turbo requires a different manifold to the k03. It raises itself away from the head of the engine and so allows the turbo to sit higher than the linkages. Also it pushes the turbo further away from the engine due to the manifolds increased depth. This would be a good solution for the k03 guys to overcome linkage issues. But remember also a new DP would be required, but this shouldn't be a real problem as ubber DP designs exist for the K04 DP. The K04 mani's go on ebay really cheap.
Unfortunately the k04 eliminator turbo costs more than the k03 version.
