It really shouldn't be that hard.
what year is the B18A you have? 90-91 B18As are OBD0 - they have a different distributor than your car needs. If you have a 90-91 motor, grab a 92-95 distributor (or 96-00 if you feel like repinning it) and use that.
Assuming you have an OBD1 distributor, reuse your stock harness and extend wires/ change plugs as need be. use LS ECU or chip P06 DX ecu and you're done.
