I would recommend buying an obd2 swap so you don't have to hackup an obd2 harness to run obd1 components.

Buy a obd2 gsr swap.

Buy an aftermarket intake manifold such as the Eddlebrock for a turbo app.

Buy the proper rear L bracket needed along with the proper top drivers side mount bracket & a/c bracket.

Buy the proper throttle cable.

Buy a obd2 to obd1 conversion harness and chipped obd1 ecu.

Convert your IACV wiring from 3 wire to 2 wire (phearable.net)

Good Luck.
