A heavier engine(like the H22) would probably be a detriment to your handling. You might be better off swapping in a B-series engine if this is your daily driver and you don't want it to handle like a brick. If it's a trailer queen and you're doing strait line then the H22 would probably be best. As for it fitting, I think it should(I mean hey if it'll fit in a Civic).
Yeah one of those should do it. You might want to try doing suspension stuff first, since you like twisties. You'd be suprised what a difference it makes.
