i'm in the process of building a turbo LS and it's time to buy pistons. i'm just a student so the motor will be NA for a while until i get enough coin for the forced induction. my question is:

1)what is stock compression on a LS motor (to see how my current LS motor is doing)

2) what would be the ideal compression for a safe LS turbo setup? (keep in mind the only real performance parts will be pistions and connecting rods)

3) does anyone have any feedback on endyne pistons?

thanks in advance.

I dont know that there is an ideal compression for boost. The lower the compression, the easier it is to tune and avoid pinging, however you will also need to run more boost to make the same power as the people running a higher cr. Pros/cons either way, I'd stick to right around stock CR, like 9:1.

I would bet that you can get feedback on any type of piston or rod by searching.
