Does anybody know what the cm2 is on a exh housing with a 1.28 A/R ? this is a w/g k31 turbo that i picked up cheap and im trying to determine if the exh housing is too big for a street compound setup. is a 1.28 a/r exh housing going to be a too big????????
or does anybody know what the A/R is on a k31 that industrial injection sells in their compound kit?
thanks
