    they are supposed to have decent iron sleeves... so forced induction? lol

    otherwise, i don't think you can add a b16a head and add vtec to a b20a.

    not much you can do besides basic bolt ons for a few hp, or forced induction if you want more.

    the b16 head will not fit on a b seires motor from a prelude or accord.

    yeah, that's what i thought. B20a or b18a (not the b18a1) aren't compatible to 'normal' b-series parts. However, that being said, the sleeves on the b20a are supposed to be better than the 'normal' b20, which is normally the b20's weak point. As a result... the answer is... forced induction.

    just gonna put some emphasis on the FI. lol

    Just curious but would the older b-series intake mani's fit on the b20a5? If so I was gonna say find a gsr intake mani, throw a cold air on there, if you can find it a full exhaust. I wonder if the later gsr cams would fit either? Maybe swap in a b21 block?
