So my biddy pussied out and bought a sr20det for his 98 240sx, I told him for months to just biuld the KA up and it would eat SR's all day long. Anyway Anyone have any links or sights they knew of to help out with the wiring? The swap looks pretty striaght forwad but the wiring i'm not sure of, I'm a honda guy as most of us are and i'm not sure if the whole harness needs to be swapped out or just certain pins ect. Any help would be great.

SR is a smart move. KA's cranks are not fully counterweighted and the R sucks dick. KA's can hold HP, but not revs. Had he kept the KA you would not have had fun helping him change rod bearings every few months.

The swap is simple.

Remove the KA, and remove the engine wiring harness. It will unplug from the body harness under the dash near the ECM, you can then pull it through the firewall hole. Swap the KA body harness plug with the SR body harness plug. Bolt in the SR, and make the wiring harness fit. You may need to extend some wires, but you might be able to get it to fit. Then bolt in the other ----.
