I'm running the stock OBD1 ABA 2.0/Motronic. With a better designed exhaust, it would likely perform better, but it performs just fine as is albeit with a little lack of torque in low end. I suspect it gets decent fuel efficiency. It ticks like a clock. Don. If you go with the ABA/counter flow head setup, try to get an OBD1 ABA block. I have read that there are subtle differences in the head/springs. Check out this link for more details. (some neat pics of head cut in half and shots of intake ports) http://forums.vwvortex.com/zerothread?id=3875757 And if possible, get one with oil squirters. It's a myth AFAIK, that all OBD1 have this. You actually have to drop the pan and look, or cross-reference numbers (off the block?) with a pro manual of some kind. If you go with a stock ABA, again I'd suggest OBD1. It's simpler in terms of wiring IF you stuck with the Motronic. (likely you wouldn't) My personal thought would be to stick with stock as much as possible. I'm sure you'd have enough fun rebuilding whatever engine with stock parts. Still, the SportTuned kit looks interesting. I imagine the cc gain is in the head/piston combo. Any chance the SportTuned head would be a different enough dimension to interfere with the frame?
