you can run the b20 using the obd 0 ecu thats' in your car now. just drop everything in, swap over to the b18a1 manifold or an aftermarket one do some custom wiring and your set. if you want , you can convert to obd1 and use an ecu from any manual 92-96 ls,gs,rs, integra. Do some more searching pertaining to parts that you need, but you can bolt the dizzy,alternator,starter, driver side block mount and intake manifold from the b18a1 and swap it over to the b20 along with the mounts from the b18 and it will drop in like it was the original motor.
