use an rb25 ecu and the rb20 loom. get 6 rb25 injector plugs off an rb25 loom. cut and shut the plugs, and make sure you wire injector 4 to plug 6 and injector 6 to plug 4 (or you can switch the wires at the ecu end, whichever you prefer. use an rb20 ignition amplifier or you'll fry the ecu (personal experience!). you'll also need to run wire up to the nvcs from the ecu if you want to use it.
