I haven't seen this done. Is it not possible to do? I have a blown 4agze aw11 motor and a blown 4age bluetop (maybe something useful on it) and I was thinking of frankenstining something together with a 20v head and a supercharger. Those 20 valves on ebay are sooo cheap, and the head by itself is 150-$200. Maybe I could use the crankshaft and rods from the 20 valve cuz my 4agze ones are shot, the ze pistons, and the 20 valve head. I'd have to go stand alone, wouldn't I? The sc or 20 valve ecu's wouldn't work with that mix?
