Forged Pistons for Turbo Build

As far as Summit's LS parts go, there is a lot of info over on LS1tech about them. I wouldn't be afraid to run them, seem like quality stuff.

That's about what I was going to say. The weak parts on Gen3 motors are really the rods. Not the pistons.

I think a lot of people think forged pistons are a must for boost. They pretty much are on old school engines. The fact is, cast pistons are pretty tough, they don't take heat and detonation well though. Because the LS has fairly even cooling and excellent fuel distribution (with MPFI) the pistons usually stay cool and live a long happy life under moderate boost. Go lean and that changes fast though.
