twin v8 busa

thinking of coupling two 1300cc hayabusa engines together by connecting them to a limited slip differential where the axel would usually go and then attaching the drive shaft to another diff to power the wheels. can you think of any mechanical problems i might have would an open diff be better? thanks.

How are you going to get one engine to spin backwards? If you connect each engine to one end of the axle (where the wheels would normally go) one engine will be spinning the diff "forward" and the other "backward". So if using a limited slip you'll destroy the clutches and if using an open diff you'll get virtually no pinion output.
