they are the same except s14's have internal coil in the distributer and s13's have external. my harness runs the s14 motor and coil on the stock s13 ecu. makes for a cleaner engine bay. all the rest of the plugs are the same. so if you put a s13 distributer in the s14 motor you wouldn't need the custom harness.
and $20 for the flywheel.
