Got the car off a friend for $150 it ran and drove before I pulled the engine and trans to freshen up. Pulled the heads and 2 cylinders on passenger side have damage around the lip. We're can I get oem grade Pistons with out having to pay a arm and a leg from Nissan. And does anyone know what caused this. A lean issue?

possible detonation i would think. you can get stock piston kits for a fairly good price if you look around. i got a set from rockauto.com for my NA, slighty bigger but to OEM specs. can't remember the brand. the kit was around 150 bucks maybe a bit more. they have been working great.

Might not be able to get them from the dealer anymore. Nissanpartsdeal is showing turbo piston with pin for $66.77, but with the Limited Availability caveat.

If you are just trying to build a cheap daily driver or fun car you could try to get a pair used. Another option would be to swap in an NA bottom end or even a complete NA engine for a little more compression.

I thought the wrist pins on the z32 Pistons are bigger is that not the case?
