Other than the motor it's all the same. I'd never change it Steve. being my second 06 sti this one runs rings around my first one. First one was typical subie understeer. This one handles amazingly. The first motor died when a mate changed from sixth to third at speed and it over revved. It was still running perfect. I dont plan to push this motor stupid I just wanted it overengineered and mainly focused on torque, response and reliability
