This piston set comes with locks for a floating wrist pin. They can also be used as a press fit pin by leaving the locks out and pressing the pin into the rod.

No these are not forged pistons. These are hyperutectic. We do not suggest them for any type of forced induction, especially at the level that you are looking for. Sorry we do not offer a piston that is designed for that level of boost.

We apologize, we used to have this option available, however, we discontinued selling these pistons individually. However, we show we have one single piston left in the .030 size (part #474217-030-1). Otherwise, we have the full sets in stock.
