if there was an 89 accord that had pgmfi, which they do, an ecu swap, intake mani, throttle body, sensors would be needed. if there is a difference in power most of the parts (CAMS) are interchangable. they would have also had to modify the engine harness to do so. its the same concept as converting a civic hatch. if you need more info let me know and i can do a litte research. the parts you need you can prob get them cheap.
