Lolz. I'm just going by the numbers, pure and simple. I've never even seen a F20B, but it just doesn't add up on paper to be a high RPM engine. Wouldn't be my choice of swaps when H22s are readily available in this country and have better geometry and easy to find parts, but that's just me. I have different criteria than just being different from everyone else.

Sounds like a B20/VTEC would give you the same starting point as an F20B, but with a 1.54:1 rod/stroke ratio and who-knows-what compression.
