| The instructions in the box for wiseco pistons call for 0.0025 inches of clearance. This is at odds with the sports compact car 300zx buildup which says that that kind of close clearance is best for high silicon alloys. Wiseco makes theirs from 2618 which is not a high silicon alloy (AFAIK) Finally there is a post from Ash somewhere on this site or another recommending 0.0035 clearance (sorry couldn't find it but I remember it well). So what piston wall clearances have others gone for with wiseco pistons?
