Thread: compression ratio question

i doubt you can grind 4 pistons and keep them all balanced. oem det pistons are only like $60 a piece, you won't run right with used pistons from another engine unless they were extremely low miles, just get a new set. you can also get some upgrade forged aluminum for only a couple hundred more

whats wrong with used pistons?

putting used pistons back into the same engine is fine as long as you check to make sure they are round and not worn etc. but i have been told by a couple people that i trust that its not a good idea to put used pistons from one engine into another.

if you are going through the trouble of tearing down an engine, why not spend a few bucks and get new internals so you basically have a new engine. unless you are on an extreme budget and you have the used ones sittin around and are in a pinch just grab some oem det pistons for 240 for a set or some forged wiseco or JE for maybe twice that.
