you'd be better off useing throttle bodys that carbs, looked into both the carb's have more restrictions and tend to act the goat and be a bastared to start.

You'll be lookin at new pistons, new injection stsyem, new ignition system, new exhausts including manifold, you'll have to fit pumps in the tank, get the head reworked.......and the list goes on.
