    go b20, i would take the bigger displacement. . . reliable is a tricky word, because they can both be reliable, but not if you run them like there race motors

    I say go with the B20 and get those RS machine cast pistons for it. They're cheap, and have the same dome profile as the ITR pistons, but in 84mm.
