I am going to come up with an obd write up lol. The year of the motor does not effect the obd in any way. All OBD is, is your distributor, injectors, wiring, ecu and sometimes alternator (obd2 has square plug). So if you want to put an obd2 b16 in your obd0 car and keep it obd0 for instance all you do is use parts from an obd0 jdm b16. If you want to convert you obd0 or obd2 car to obd1 for tuning purposes then you need a jumper harness.
OBD> Match ecu, harness, distributor, injector plugs/injectors
