Stick with the simpler Digijet and get one of the Euro-chip ECU's from Boston Bob. It works! Jay

Thanks for your input, Karl. We've reached a decision and are about to install the engine/trans tomorrow, using the 2.1 cooling system and 1.9 fuel system. The 2.1 fuel system wiring from the donor car was not so good, plus I've heard reports that a 2.1 with Digijet runs even stronger than Digifant. We'll see. The cooling system was a no-brainer once we looked at the difficulty involved, which was basically a trim to the length of the steel pipes, fitting the plastic junction to the front side of the firewall, and a short adaptor hose cut from an old 1.9 hose.
