Piston Choice on 318

Thanks, they look good. I am not too nuts about those hyperuetectics pistons. You go too lean on the A/F or give it too much timing you be looking for a whole new motor.


I do seem to recall some question as to whether they could stand up when they first came out. Hi silicon content leads to brittle metal,and it was felt shattering could be an issue.

I dont think it has been. But Im carefull. Nitrous abuses the internals something fierce. Seems to me a forged piston would be a better option.

I dunno. Would you prefer a cast hyperuetectic wrench over a forged one?LOL!
