obd2a > obd1 jumper harness
obd1 p72 ecu
b-series mounts (trans, drivers side, rear t-bracket)
axles from a 94-01 integra or other b-series axle (del sol VTEC, etc)
shift linkage from integra
throttle cable from an integra
throttle cable mount will need to be modded
youll need to wire your car for VTEC unless its an EX (pressure switch and solenoid)
knock sensor if applicable (cant remember on obd1 gsr)
youll have an extra o2 sensor from your setup, just remove that from the car and plug the hole in the exhaust
youll also need to do a couple small wiring tricks, one involves conversion from a 3>2 wire iacv, and you may have to do an iat as well, i cant remember if obd1 gsrs have them. this should get you started
