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

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.

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

ochsy03

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.
