I've have a b18a1 motor does anybody know any kind of information on b18a1 motor? I am thinking about putting it in a 1991 Honda CRX but first I want to build the motor is there any heads I can swap or any other information?
Thanks two fast 4 you,

 

it depends on the year of the motor a
90-91 b18a has 130hp@128 tq
92-93 b18a has 140hp@128 tq
you could do an ls/vtec(vtec head modded to fit on the non-vtec block) and depending on how the ls/v's built is how its gonna run
