Can the 4V forged Cobra pistons be put in a 3V? I know they will physically. But as far as PTV etc is concerned.

They'll work but you'll probably want to use limiters with the timing.

Why would you want to use them? the CR for those things is stoopid low.

I guess what I'm getting at is the easiest way to get a forged rotating assembly.

There's no reason to run that low compression, Even being FI the car would be a dog to drive off boost .

If you're sure you can use a stock bore piston, I'd go with the old Saleen CP pistons, you can find a few sets for sale if you dig around other forum's for 300.

CP Pistons 06-1603-B12131, Those will net 9.3:1 CR. still alittle low but better than 8.5:1.
