f22b block is the same as the f22a, I remember an older member doing the hyrbid, along with maybe 1 or 2 others. Possible, very time consuming, and you def need to know what your doing. shadetreecustoms I believe is the guy who did it. ill check

Same scenario as the F22B. It's doable but a lot more work is involved and in the end you won't really have something that will perform like an H22. You won't be able to rev to the H22 head's capabilities and you won't make near as much power because your car has 8.8:1 compression pistons in it now with a 50cc combustion chamber. You would be putting a 53.8cc combustion chamber on there and your compression would drop way down. You could always mill the head to solve that problem though. Still you'd have to be careful how you drove that setup because over revving it could mean the demise of your 65K bottom end.

Running forged pistons in the F block would be much easier, however. No need to resleeve to use the pistons, and you'd be able to eliminate that weak link. The stock sleeves have their limit, but you'd be able to hold more boost (or higher revs) with good internals.
