i would like to put a stock wrx tb 04 turbo. and set the boost at 5 pounds. i have 36 inch equal length headders, ems computer, it dynos 270 horsepower as is. would like to add 40-50 horsepower. ive heard alot of stories of the 3.3s internals not being strong enough to handle boost. i am wondering if anyone had turboed a 3.3 or blown up there 3.3 with too much boost. With only 5 pounds, do you think i would need an intercooler?
