Thanks again for all the input.

Coolant
I took the thermostat out. Now the water circulates fine and I have good
cooling. Even the cabin heater works :). Does the third gen have a
recirculation hole? My theromstat housing just has space for the thermostat.
No other holes.

Oil
I took off the oil feed to the turbo and cranked - lots of oil came out :)
The oil coolers,  pipes and filter are getting warm. The turbo wasnt damaged
as far as I can tell, and I don't think there's a problem with oil
circulation.

So... now I can run the engine as long as I like, but it needs a lot of
tuning. Starts well when cold, but seems rich when warmed up. I read the EC2
manual. Anyone have any additional tips on how to go about the programming
steps?
