Use N/a everything, engine loom, fusebox etc. Chop the bits you need off the GT ENGINE LOOM and replace them with the bits that dont fit the fte engine on the n/a engine loom. Its basically Knock Sensor, Ignitor, Distributor, Coil, Sensors on the inlet/tb. Then use the diagrams ive linked so you put them to the right places, and swap a couple of the pins round on the ecu.
The diagrams i posted is all you need.
