If it's a SOHC- 2" on the hot side, 2 1/2" on the cool side.
If it's a DOHC- 2 1/2" on the hot side, 3" on the cool side.
That's pretty much the norm. 2 1/2" all the way around should be alright.

2.5" piping is ideal but 3" is what you want if your running for example a gt40r or larger turbo.Carlos

comon man avondale is 5 min from newark damn reading i dont even think i have ever heard of that i just moved out here with my fiance and its a big change from delaware even 5min from de
but hey i am running a h23 dohc and i have 2.5'' just thought it looked to big for such little boost 10psi but hey 2.5 will have to work and i hope it works good
but thanks to all you guys for your input if it wasnt for this cb7tuner crew i would be lost with my car you guys seem to know how to help somebody out
thanks again

damn, you guys don't mind serious pressure drop and hotter turbos making hotter compressed air, huh? to combat pressure drop from large charge pipes, you have to up the boost, which decreases thermal efficiency, the whole "good thing" about a turbo, basically.
i was making over 350 crank hp with a t4 and 2.25" i/c piping.
with 2.5" i got too much pressure drop and it didn't increase the power at all. there was no benefit to the larger plumbing.
the thing is that your intercooler is usually always going to be far more of a restriction than even 2" pipe, but you want the charge pipes to be as large as possible while experiencing VERY little pressure drop and/or power loss.
3" is just too big for MOST streetable applications. if you aren't moving a ton of air (not that possible with a street-built 2.x liter engine) then there is no need for a ton of space.
on your exhaust, bigger is better because it decreases backpressure, aids in scavenging and keeps the combustion chambers as cool and clean as possible.
i experienced turbulence in my charge pipes at 2.5" with the t/4 at 20psi on my ford 2.3.....and on the 7th day, deevergote rested and called his mom.

ever seen a stock turbo'd car? IC piping is usually quite small...1.5" hotside 2" cold (tops).
I run 2" piping both hot and cold...steel on the hotside (actually 1 7/8"), and 2" ABS piping cold side.
What's funny is the guy above says he had pressure drop with the big pipe. Big pipe should do the opposite, it should increase flow and decrease the pressure drop.
Albeit, with 2" pipe all round i have a 1.5 PSI pressure drop at 6700rpm...but no way to tell if that's the IC or the piping. For 200whp or less, 2" is more than enough 250whp 2.5", 300whp 2.75", 350whp+ 3". That would be my recommendations.
I'll be pushing 250whp by the time i'm done and i dont' lose any sleep over the Pressure drop. In fact the efficiency is a bit better higher in the Pressure ratio anyways.
