You need the motor mount of a 88-91, a harness(the original one for your car) a 88-91 manifold, a 88-91 exhaust manifold, a 88-91 distributor and a 88-91 ecu. This is the eaisest way to do it. You will lose some power because you will be making the car a OBD-0 but you will barely notice it. That is everything for the engine. Have fun!!!!
