if your going to switch to multi port you can modify you harness. just the the injector harness wiring off a civic/ crx si and resistor box (cut as few wires as possible). you will also need a crx/ civic si distributor and ecu. (im selling those to on the cheap) you can also just use the jdm d15b injectors and find odb1 injector plugs and not worry about a resistor. pm me if you need help
