but that was with a de-stroked 2.1 liter SBR motor probably spinning at 9829389283 rpm

 

I have the TO4r from peakboost and the the stg 3 wheel is good for 625 whp and the stg 2 wheel is good for 710whp so keep that turbo in mind, i don't have the money to install my kit yet so i can't give you any ideas on what spool is. I believe Ken at peakboost hit full boost at 4500 rpms with the stg 3 wheel.

 

I was searching high and low for a 700 WHP turbo that could do the job but ruled out the GT40R as the rear housing is ridiculous to spool even on a stroker. I know ATP's casted a .85 A/R housing now which might just work for a stroker. The only other option is the Peakboost ball bearing P trim T67 in a .82 A/R configuration. That will work for sure.

 

This is what I suggest. Just MY suggestion, so if you guys don't like it, meh. There's a lot of random information in here and some of it sounds very honda-tech-ish(I heard from this person's mom's sister's brother's step uncle or I made 500whp on 10 psi (creeping to 25-but no one needs to know that.). In my opinion, this is what might probably work for your power needs as it will be what I'm gonna go with temporarily.

GT4067 (GT40 exhaust wheel in a .68 T4 exh. housing with a 67mm compressor) or a GT3767 from PTE/anyone who can get you a GT37(exhaust wheel) with a 67mm(compressor wheel) also with a .68 T4 exh. housing. I would have to say full 35 psi would be mid to high 5000s on a dyno and would net you mid-high 600whp if not low 700s on 34-36ish psi.

If you want to make it simple and don't mind a little lag(35psi on the dyno by 6100-6400rpms), you could always do a 71 or 74mm compressor/GTQ or GTS (cut down versions of the GT42 exhaust wheel used in the "GT42R" and variants) on the 2.3L, run 32-35 psi and make your 750awhp. Of course I'd hope you're planning on building your motor to be able to rev upto at least 8.5-9k.

That's my .02. Whatever you do, don't get one of those mismatched t3/t67(t3/"t04R")turbos that use a stg5 or stg3 exhaust wheel with the 67mm compressor wheel to try and make your 700whp. Honda guys swear by them up and down and if you know anything about honda power curves, they're typically peaky Vtec powerband/curves/numbers.

Have you thought about getting a FP3575(the GT3767 wheels with a nice exhaust housing)-Buschur setup? I'm sure it will make you the high 600whp/low 700whp you are looking for on enough boost.

 

37R Kit is the way to go. We can now do a full 3"02 housing on the turbo kits so there is a definitive advantage in spool. We plan on making 700+whp with ours this week if we have time. Last time on the dyno it made 609whp at only 27psi. At 35-38psi it will easily be over 700whp.

 

I am using a Buschur 2.3l stroker. Everything that is in my sig is already on the car or getting installed on my car, except for the cams which I'm still trying to track down.

I am going to do more research on the GT40, but I think the 37R is the way to go.

 

GT37R is the way to go if you want to have 2.3.

 

How about a T-04Z with a .81 A/R

 

I have a T04Z in a .61A/R. I can hit 30PSI around 6k at the track on a 2.0l DSM with all the fixings. I definitely wouldn't run the .81 housing unless you're going to spray it.

 

FP will make you the 3575 in a T4 exhaust housing upon request.

 

get a 42R

 

Ya the 37R is the way to go with the 2.3

 

I thought that pruven hit 700+ on a GT35R they came out in the turbo magazine.

 

I don't think anyones hit 700whp on a straight 35R yet without some juice.

 

The 35R isn't going to make 700whp all boost. The compressor only flows 65 lb/min. 65lb/min = 650hp and that's suppose to be crank but we all know it can make it "whp".
