I am looking at doing a b18a/b with stock compression ratio and not reving over stock limiter. I want around 350 horsies to the wheels at no more than 20psi. I want a t3/t4 garrett type turbo. What ar sizes should I get for compressor and exhaust sides? Basically what I am asking is at what horsepower would each size turbo run out of room to breathe?

t3/t04E will get you to 350whp easy. Even a B trim will, .63 a/r or .48 if you want fast spool (traction problem on street tires) I have an extra t3/t04E from a revhard 2c kit that is rated to 450whp, let me know if your intrested.

Thanks. At what rpm do you think the t3/to4E with .63 ar will see 10lbs and what horsepower if tuned right, on the aforementioned setup, could it make?

Anybody else have any opinions?

T3/T04E
If I were you I would go with a .57 trim compressor.
Its efficient from 10 to 19psi for your application
(1834cc, peak tq @ 4400-4800rpm, 6800rpm limit)
Turbine will depend on where you want it to spool up.
Spooling up early is not always good in light fwd.
Like IMPULSE B18C-T said, the .48 a/r housing might cause traction problems.
Get it though, if you like to stay in one place and burnout ..

Don't like doing that to much right now. Its just not as impressive when its only one wheel doing all the work. My friend is picking up a tranny with welded dif. If I like that I may end up doing it also. I will probably go with the .63, maybe it will help with the launches a little.
