ok..certain things would have to be re-wired/re-plugged.
o2 sensors and injectors because you cant plug those straight onto the motor because then you would have to be running obd0 injectors and obd0 exhaust manifold...but that wont work because your ecu will be obd1...which means you have to re-wire your injectors for non resistor box injectors...score some obd1 injectors, and you will have to re-wire the o2 sensor to be a two wire single o2 sensor, instead of the obd0 two sensor setup. also you will have to transplant all your VSS stuff over to the hydro tranny because it is a direct drive as opposed to a digital unit. but you will have to do that anyway
