I'm doing a turbo build on my f22b1, i made 280 whp on 10 psi. And now i want to go bigger. Who makes aftermarket rods/pistons for the f22b1.

I know i can run h23 rods, correct. But what about a low compression piston?

 

bisi had a set. Don't think they still do. You can always get custom pistons made to your specs from any company.

 

I know bisi has a 9:1 ratio set, but I'm not sure about the rod length in that set. It's $749 shipped, both rods and pistons. It's not on their site, though. Email them. That's what I did, and that's how I know they have the set. Ask about the specs, though. I didn't end up purchasing them because the ratio wasn't high enough for my n/a build, so I didn't get any more info on them.
