compressor pipe sizes

[kelly]

Hi
Is there anyone on the forum who can tell me what size compressor pipe to use from the turbo to the front mount intercooler and from the cooler to the intake manifold. I'm gonna use a GTX3071R turbo with a topmount exhaust manifold, im busy building a racing car..........GTI R of cause

It doesn't really matter what size you use unless you have some specific power level in mind?You can just mate it up to your intecooler piping with a silicon reducer.
I just bought the wastegated gt3071 with 71mm inlet and 51mm outlet.
