Allright, I have been getting some help with my upcoming motor swap. I am working on doing an ls turbo into a 90 crx. What I dont know is if its okay to use a b18a1 vs the b18b1 motor. I would rather use the first because its the same gen. motor, so I think swap would be faster. But I do know that the b18b makes more power. I am going to be doing rods, pistons, cams, sleeves, etc, so am I going to see this power loss? And what ecu do I want to use, the b18a1 (obd0), or the b18b1 (obd1). I know if I use the older ecu that I can't use hondata like I would like, but how much work is it to swap ecu's from the b18a to b18b? Any help would really be appreciated guys. Thanks
