RWD though...but look how high the rear suspension has had to be made to clear the spaceframe needed to contain the engine.
Plus designing or adapting a suspension will be quite a bit of fun (i.e. not) considering your stock Girder-rear suspension will get in the way, not to mention what to do with the fuel tank, wiring etc, oh, and don't get my started on Chassis Stiffness - being a hatchback, and the lame P/L Chassis, you'll need a HELL of a lot of strengthening, it's just all tackwelded sheetmetal back there!...but when completed, it'd be unique. I recall Zep Racing had done a RWD conversion... And apparently the Hayabusa, or any motorcycle engine struggles after a while as they're designed to pull along a vehicle that weighs 300kg at the most...and not something that weighs 3 times that.
