Would a thermostat, cold start injector, and the warm up regulator from a 1988 naturally aspirated model fit on a 1984 turbocharged model? The car from 1988 has a catalytic converter and the other one does not.

What thermostat do you mean?
It will probably work. You'll need to adjust the mixture using a pulse-relations, dwell, or frequency meter.
I've never seen a bad cold-start injector, what are you trying to fix?

The car is running far too rich and I can't find any obvious vacuum leaks, so I decided to see if replacing these three things would help. Two bolts snapped when I was separating the outer parts from the head to check it out, so now I need to know if the parts from my newer car will allow the old car to at least run for a while without damage when driving calmly.

This is not my actual engine bay. The parts are in the correct positions however.
