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?

really cool rail, how much travel?

a wrx turbo would come on very low(off idle?) and fall off low too. way too small for your app. IMHO. that turbo is for a 2.0L and 227bhp at like 11psi. it would be blowing really hot air on the EG. two TD04's would be good. get a bigger single turbo like a holset HX35 and methanol/water injection kit then maybe 12-15 psi. chemical cooling=no need for intercooler. with 10-1 and boost that thing is going to rip.

also for low boost an eaton M90 supercharger off a ford 3.8 supercoupe would be a good fit for the 3.3L and they are cheap to buy you just have to be able to do your own setup.
