its a direct replacement engine and transmission (clutch is different though). you can use obd0 or obd1, that is up to you. obd1 conversion is covered in the teg tips section.

like the old saying goes, there is more then one way to skin a cat.
Read the swap Guide in Teg Tips. Dan covered almost everything that you will need.
You will need an OBD0 to OBD1 conversion harness for the 92 ECU. Basically the only things that you will need to rewire are heated O2 sensor (covered in conversion harness) Distributer harness and delete the resistor box from injectors. It is about as basic an engine swap as you can get.
