This idea is about as useful as supercharging a 4cyl. IMO, why would you willingly trade torque for a little more high end horsepower? One would say " more rev's means higher top speed" but that’s not true unless it has the ability to push the car past the air/weight speed barriers. That and I would think this type of engine would be better suited to a drag racing engine backed by an Auto tranny (unless you're Takumi) and we all know how everyone feels about the ATX. That and I've never seen a transbrake for an A604 (Infint3, we need you). All in all this would make for a really fun albeit disappointing money pit of a project, so if you have the funds and patients, go for it and see what you can end up with, otherwise, stick with proven.
