Technical details aside, I'm still not sure if you realize that 450 whp can be achieved with the "dinky" 4 banger sitting in your buddy's LS (via forced induction). Of course if you really want to get 450 whp all-motor, you'll still have a hell of a time clawing the pavement with your two front wheels.
How about an Integra with two engines? B18b driving the front-wheels, and a 2JZ-GE (mounted in the hatch) driving the rear wheels?
