how strong are LQ4 pistons? Hi guys. I am in the rebuilding a lq4 that I got pretty reasonable but the question I have is exactly how strong are the factory lq4 pistons? I am planning a turbo build with somewhere around 6-700rwhp and was wondering just how much abuse the factory pistons can handle. I know the rods aren't really the strongest in these motors although they are stronger than ls1 rods, so I am planning on replacing them with some forged rods. Just wondering if I might be able to save a little coin and reuse the factory lq4 piston.

Unless you have The newer floating pins, your going to limit your rod choice as most use a .927 small block Chevy floating pin.
I'd imagine your going 10 plus psi? I don't know what boost levels others have taken stock pistons to but investing that much money on a turbo kit, I would replace them.
A good set of mahle pistons can be had for just over 500 bucks. I got my wiseco's for just under 700 shipped to my door from hke.
