    they will fit.. you might have a little piston ring gap issue, and possibly a low compression psi, but otherwise it sounds like a great idea.

    81mm ITR pistons will NOT work in a B20.

    the itr pistons will be rattling around in the b20 cylinder. you wont even have a seal.

    yes, i am kidding. a 1.5mm piston gap and 0 compression might be a "little low" :lol:

    Just use JB weld to make some extra extra thick rings.

    in a B20A(old prelude) they will fit but not in a B20B or B20Z(new CRV) or in a B21A1(old prelude si).

    B20A=81mm bore :D
    B21A1=83mm bore :(
    B20B/Z=84mm bore :huh:
