i got a 99 civic si with a t3/t4 turbonetics turbo(drag gen III kit) and im buildin my motor right now and thinkin about upgrading my turbo. right now im puttin out 222whp at 8psi
i want anywhere from 375+ whp

heres the turbos i was looking into
SC34
GT32
GT28rs

my question is...what would be the differnent whp #'s for each turbo at about 18-19 psi?

 

well, the gt28rs wont get you to 375, so scratch that one off of the list. I'd go with the gt32. its basically the garrett gt wheels in a journal bearing chra. If i remember correctly it made 8psi by 4200rpm on a stock gsr. The nice thing about the gt is that it will make nice power on the topend, where teh sc34 tends to die off

 

gt32

 

alright guys thanks for the advice

 

sc 61 they make topend power

 

yea i was just gonna ask about the SC61....would that be better for my setup?

 

sc61 make crazy power

I made almost 380 on a GT28RS, plus I had way more torque across my RPM range than I had with a bigger turbo. If you want power that you can use outside of a dragstrip (and at a dragstrip too), I'd go with a GT28RS. I've seen guys with SC61's make crazy power, but it takes forever to spool up. I had far more torque (20-60 lb/ft) below 5000 RPM with the GT28RS than with my GT3071R.

supertech is a pretty good brand, and can't be beat for the price

 

I'd keep a stock head setup based on the turbo he has.

 

yea my head is gonna be pretty much stock.....im still lookin for alot of help on my setup and wanna know from people who have experienced high hp motors and what parts they used.

also what are some good online stores to order parts from?

 

camp1320.com

That's his HT SN...he sells **** for crazy low prices.

I've bought stuff off of camp1320, great prices and no problems, plus he can get about anything.

 

The T3/T4 included in the Drag Gen III kit is efficient up to about 450 HP, so it should be fine for your HP goals.

My ACT XTSS started to slip when I got above 370 WHP, I upgraded to the XTR6 and it holds fine now.
