Its not going to work. V12 knocks out around 300 ft.lbf. I'd imagine the diff might end up loosing teeth off the gears. So you'll have to get a better diff, betterdrive shafts, new uprights, brakes to suit and a redesign of the back of the car. Even if you overcame all these problems, it would be chaos to drive. I believe the saying goes "Power is nothing without Control"
