you could stay with the t4 flange and get a 37r turbo. that way you won't have to get 1 off headders made, i think the 37r is good for 700hp+

bertune · 08-03-2008, 11:50 PM

Consistent tens with 520whp on stock internals!

........I honestly do think you are the one that should be giving us some advice!

Jumping to the t4 would be your best bet. Stay away from the "37r" it isnt a very good turbo and as geoff from fullrace told me there is nothing "r" about this turbo. Its old! Go with a 40r or something similar with a twinscroll setup and have slightly less spoolup time compared to your 35r but about 100 more whp possibly more? Or you could do what I am going to do and get a twinscroll borg warner s366 and gun for north of 700whp with that!

Thanks for the advice, I will read up more on that.

Also, any suggestions on how I should go build my own engine or go some type of short block ?????

tino · 08-04-2008, 10:43 AM

700hp all boost ull need to go with a GT42R imo....

a GT40R will just get u 600 hp atw...

Engine will need to be built i,e sleeves as a minimum and CD if ur keen... heads will need to be ported with atleast 1mm oversize valves and cams...

To my understanding there is an older GT37, that is not the same 37R that most talk about now. I think the 37R was introduced by AMS and it is not an off the shelf turbo, what it actually is, it's a ball bearing version of a T67 turbo. Evos are known to make the kind of power you are looking for with the 37R, i personally made 638whp @ 28psi with a 37R and a T3 housing (subi), i was looking for 680+ out of it but i do think the T3 housing is holding me back as i can't past 28psi. I would not buy a 40R coming from a 37R, it is a new platform going twin scroll, twin wastegates etc. If i am going that way i would definately go 42R. Borg warner turbos are nice too and cheaper.
If you have a good engine builder it would definately be cheaper than buying a built shortblock, but if you are thinking of buying a block and cosi heads why not go cosi all the way?
What's the weight of your car?

gt40 is a t4 turbo.

I guess you answered your own question.......

Thunder STI · 08-04-2008, 01:00 PM

so, Do I need to get rid of my setup and start from scratch, In fuel system, also I want to reverse the manifold.

any suggestions in that area ?

Thanks

icslowmo · 08-04-2008, 03:57 PM

Looking at Garrett's web site:

4088R=~700hp(whp~600-630 depending on tune and fuel)
4094R=~800hp(whp~700-730 " ")
4294R=~850hp
4202R=~1000hp

I would use a 42**R turbo for those numbers. Also I've talked to AR Fabrication and sounds like they build some strong motors..

700hp · 08-05-2008, 05:50 PM

I made 678whp with the 35r 1.06 hot side at 28 psi. My 04 sti ran 139mph all boost with that set-up so maybe the 35r is enough. I had about every supporting mod you can think of though. Don't buy anything you don't need that how I feel.

MrH00nel2 · 08-05-2008, 06:09 PM

a 35r with 1.06 can do more than people think... and thats from personal experience

i have recently moved to the 4088r twin scroll. thats plenty

Unabomber · 08-06-2008, 10:07 PM

I'll probably get killed for saying this but you might consider getting a closed deck 2.0L motor for this. If you want the motor to last, nothing beats a closed 2 liter.

Splinter · 08-06-2008, 10:23 PM

Have you considered going to a twincharged setup?

or, doing a closed deck modded 2.5L

that might beat the old closed deck 2.2 or 2.0L....

Splinter · 08-06-2008, 11:10 PM

The 2.0L closed deck has much, much thicker cylinder walls.
