With a newer model CPU and larger injectors and some minor tuning the factory turbo will max out around 300rwhp. With a stand alone fuel system and MS2 and larger turbo and head work it will climb close to 500 at the wheels. But I don't have much interest in doing all the work needed for that. It's got a great list of upgrades already and is a decent car the way it sits. I'm hoping for high 12's with the new parts and weight reduction.
