Hey man, my name is Steven and i have seen you post tons on here. If you didnt care to answer some helpful questions for me i would appreciate it. I have an old motor that i will be tearing down to see why it had terrible compression in one of the cylinders next week. (its been sitting at the shop for over 2 yrs). The one that is installed now is a F23A from japan. The first motor was bored 20 over, so i know if i use that motor i will need 86.5mm pistons. The rods i was looking at using were from RaceEngineering for like 480 bucks. And they even do a package deal for like 980 bucks for the 86.5mm CP pistons. But was wondering doesnt our block or whatever require FRM pistons or do i just use regular forged pistons?Any and all help is appreciated. BTW goal is 400ish Hp with 750cc injectors and running on E-85, should the factory sleeve hold this if i use upgraded rods/pistons and head studs?
