FI engine tolerances??

It's really just ring tolerances. Check with your preferred ring mfg. Federal Mogul makes Hellfire rings for FI, and they have a chart based on use and boost, nitrous, whatever you want.

Piston to wall tolerances will change also. Your pistons should have a spec card telling you what it should be. I know the Diamond race pistons require a lot of clearance for a max effort engine.
