are there any other heads interchangable with the b20a5?

 

there are people working on swapping a B16 head

its been done, but wasnt relialble or worth the money the guy spent at all.

if you want more power, just swap an H22 into that 3rd gen that im assuming you have.

as far as other heads that swap, the B21 head swaps over, but its essentially the same exact head as the B20A. again, not worth time or money, unless you want to build one head up and then swap it over

It's such a pity that the b-series engines offered in 3rd gen ludes are the bastard-children of the honda family
