I guess to avoid a lot of pain, I would look for GD WRX as well. Perhaps same year 04. I assume the wiring, loom, etc may be identical but at least not totally different. Is it right?

I might need engine, gearbox, front axle, rear axle, wiring, ecu, loom and cluster. If I get the JDM half cut, that means that the cluster would only go to 180km/h top. Correct me if this is wrong. Can anyone advise me how to change it to Oz standard?Would buying new Oz cluster helps?

Thanks
