There is the eliminator GT28RS which is basically a GT2860RS turbo with a custom exhaust housing so that it will bolt directly to what you have. They are $1400-$1500. There is also the GT2871R eliminator kit as well which has about 50hp more potential with a sacrifice in spool.

You can buy a brand new GT2871R for $900 shipped if you know where too. I would snag it and manifold with a downpipe and you are at the same price. This route over the eliminator setup includes a test pipe which will help out dramatically. If you already have a test pipe then either is the same money. Personally I think going the second route is better. I am not knocking the Elim setups but it will be easy to upgrade later on if you so chose.

 

But that brings up some problems:
Because of the manifold being different then the intake has to be different too right? And then since that changes and you get a special down pipe what happens with the end of the exhaust? Will it end up where it was designed to go?

Also, test pipes aren't legal in my state which is a big problem since I want this to be street legal too. So this is why I really like the elim options. But please prove me wrong because I'm sure it is worth it as long as I understand what I'm doing.

Thanks

 

Actually I just looked and the chap I could get the GT2871R from is out of them but he still has the GT3071R left. It can get you 400whp but also more spool sacrificed. It has the T25 housing. You could buy the GT3071 and have cat down pipe built at a muffler place I am sure for decent price. Just buy the Cat online and the parts. They will typically weld one up for around $50-$100 as long as it is sorted out. The parts would run you about $200 and with a manifold you are still ahead of the Elim setup (using a cheap manifold but who cares, they work).

To get the GT3071R to work:

GT3071R genuine Garrett $900
Turbo Mani (cast ebay) $68-$90
Downpipe with Cat - $300

This leaves you with $200 to get your turbo inlet sorted and oil and water lines which should be doable.

You can get 300 hp out of these easy with full spool in the 4000-4500 range. Also 300whp with this turbo would be easier on the rods as you would be a lot less likely to bend one since your torque is going to be lower around 250-260lb ft from its slower spool.

Still this may not be the best setup for what you are looking for. Go to google and search AEB GT2871 dyno, and other turbo combinations and look at graphs. A good way to see when peak boost achieved is by looking at the torque curve and where it peaks. Example: if you search GT3071R and you see peak torque of 260lb ft at 4300 RPM then you can draw the conclusion that whatever psi setting they had it was achieved around 4300 RPM.

This is how I figure out how a turbo should perform. You can also use other cars dyno's as well to get a good idea. Lets say ou are wondering what TD05 20G will do since these are made with the identical proportions of GT2871R turbos and they can be used. Find a car that uses the 20G. Lets say a STi and the 20G makes 350 lb ft at 3800 RPM. Then compare that to aother Sti with a GT3071R that makes peak torque at say 4200 RPM. Since the GT3071 on the Sti spooled about 100 RPM's sooner then on a VW 1.8 and the TD05 spooled 400 RPM sooner you could conclude that on the VW 1.8T the TD05 should reach full spool also 400 RPM sooner or around 3900 RPM. You have to use dyno's with similiar boost setting and mods though. It will not give you a definitive number but should give you a rough idea.

 

Here is a thread with a **** ton of dyno's. I was actually surprised to see that the GT3071R spools fairly similar to the GT2871R.

"test pipes" arent legal in any state. my car has no cat. most modified cars have no cats. it all depends on if your state has emissions testing. i have none whatsoever, so running catless makes no difference. also, you could always run a highflow cat and fab something up

 

If you need to pass a visual, just gut your cats. Makes the techs happy knowing theres something that looking like a cat there, your happy knowing its a straight pipe.

 

I'll have to see if they do just a visual test or not.

And Zandrew, I want something that spool quicker than the the 4k RPM range since this will be used on an auto-x track and I don't see hitting full boost when leaving corners at medium speeds. I know you can make it work by staying in lower gears obviously. But I'm just really unsure of how it will be with the spool taking 1.5k more RPMS than stock.

 

its been said before. look into efr series

 

let me help

Borg Warner EFR Series

 

That is why I linked you to the thread with the Dyno's. The GT28RS really is not much faster and though it shows full boost from 4000-4500 you still have positive boost differential (meaning atmosphere+turbo) at 3000. It just does not come to full life until 4000. That is also dependent of the psi setting. If you take a closer look at the dyno's you will see that they are still making 140lb ft at 3500 and another was making 200 lb ft at 3500 which is not bad. Some of the GTRS are lower and some are higher.

Too me all these turbos would be wadded together. If you don't like the spool of one then the others really don't seem to be much better. Alas there are other solutions. There is the GT2554R which does come in Eliminator setup which will spool considerably better but its top end will be hard pressed to break 300whp; if you even can. Or you can do GT2560R which will get you 300whp and should spool between the K04 and the GT28RS. Its max compressor flow is 36 lb min where the GT28RS is 38lb min. You can actually buy a GT2554 that is non ball bearing used for $200-$400. It was the turbo used on the SR20DET S13 or first Gen red top. If you were not happy with it you can have the compressor upgraded for around $200 to either the GT2560 compressor or the GT2860RS compressor but still keep the better spool characteristic of the GT25. There is Billet GT2560 compressor availible and couple that with GT2554 turbo you are talking GT2860RS levels of hp but with the best spool characteristic possible.

At one point it was possible to buy the GT2560R new for less then $800 and that is what I would use if I wanted the best spool possible and 300whp. I have yet to see one done on 1.8t but it is excellent setup offering hp capabilities similiar to the GT28RS but with a faster spool.
