Seems fine but 600hp on a fwd? Your going to get various inputs.

Ultimately, it's going to be made AWD. For right now it will have LSD. The turbo is big enough that boost wont kick in fully until 4500RPMS or so, therfore I am not too concerned with traction. It wont be seeing track pulls either, just spirited street driving.

For how heavy a full weight 2g is, you won't see any gains with 400hp to 600hp, at least on the street with street tires. I would concentrate on torque band and not full top end power to go faster. You could even pull timing when you hit full boost where the tires start to burn off to gain more traction.
Have you considered jumping the CR to 9:1 or 9.5:1? It would make power sooner and be better for the street.

Slap on an HX40, go E85 and turn up the boost. 600+ hp will be in the near future.

Forget it 500-600hp FWD is fail on the street. Your better off with 400hp or below. My car is a nightmare to drive around spirited on the street.
