CluttenFred ..Another thought on the question of using the suzuki G10 engine as opposed to the G13BB. Yes that would have enough power but the current engine (VW) I have heard is near 200lbs is that right? If it is the G10 is only 140 plus install and fluids that could wind up 40Lbs less than the prototype making it extremely tail heavy. Not sure I would give up the fuel injection on the G13BB anyway it is fully altitude compensated so always runs well not like a carb at all.
