I have used cp pistons for sale they are 86.5mm for the sr20det so +1 size over bore for the engine. They have seen about 1500 miles on them but are in perfect condition still no detonation marks at all in them and literally no wear marks at all. They come with no piston rings sadly i was idiot taking them off and snap the rings. Reason for selling cause im going with a stoker kit for more power. All i want for the pistons is 300 pounds.
