IC piping size

[jtjerry]

Hi
I want hard piping and new FMIC for my 1990 turbo. I thinking about 16G-big or evo turbo (about 350-400 hp max).
How big that pipes should be? 2 or 2.25 or 2.5 inches?

thanks

2, 2.25 at the most... dont wana go to big if you dont plan on running a big turbo. ive got 2.5" with my evo3 16g i think its to big... (but im going to be running a fp3065)

2.25 would be fine
If you purchase an IC it will have inlets and outlets. The outlet and inlets will be a specific size. Just match your piping to that size.

I dont want overkill and slow too much airflow...
I have IC from truck iveco turbodaily and use core only from it(25X8X2.75). Someone will make for me alu sides so make all inlets 2.25.

I just installed 2.25 upper IC plumbing on my car. I didn't really expect much performance gain but holy crap! Now I know why some of you GST guys complain about 2nd gear wheel spin.
