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.
