Yeah, basically, duplicate the Lexus LF-A engine, but with more displacement, and possibly forced induction. A five to six liter engine, with forced induction, at 10k+ revs, would be a wickedly powerful (and expensive) engine. I don't know what it's crank looks like. If you are a gear head, you owe it to yourself to go and hear an LF-A engine at full chat. One of the best sounding engines of all time; easily makes my top five best sounding car engines.
