First time I bought an engine sight unseen, but the offer was too good to pass up on. But I’m sure this project will be behind schedule and over budget once again.

Shot you a PM.
On the keeping Jetronic side, I guess if your car already had Jetronic and you know it runs fine, it’s fine. Something I remember hearing back when I had my Jetronic (which did, in fact, not run perfectly - hot idle stalled when going off power and hot starts took 10 seconds of cranking while everything other than was perfect) was that if you let the fuel distributor thing or whatever go dry, that’s often where problems start. I don’t remember exactly, that was a decade ago. Mine was an inline 5 Audi though, there may be parts that are different.
Funnily enough, my hot start issue was defeated by disconnecting the coolant temperature sensor. But when I replaced it with a new one, it had issues again. I just kept it connected and put up with the long cranking as I figured it might run too rich without said sensor and waste a ton of fuel
Huh, I actually think I know what was wrong with your Audi because I had the exact same issue with my W124 before. It’s probably the fuel pressure regulator. When it goes bad it will cause vapor lock in the fuel lines under the hood after the car has been driven. The lines are no longer holding the pressure so the petrol turns to gas. When you disconnect the temperature sensor you’re overcoming the vapor lock faster by increasing the amount of fuel the distributor puts out. Otherwise you will be cranking for 10 seconds or more.
Ha, nice. I’ll take note if I ever buy another one. That said, mine was on the less problematic end of the spectrum. The part I always heard horror stories about was the fuel distributor and this is in a country where DIY mechanics are literally everywhere because of a large subculture of people with little money and expensive taste in German cars. I have no idea if online resources on the KE-Jet have gotten any better over the last decade or so though, might be that there’s actually guides on how to rebuild the fuel distributor nowadays lol. Plus I guess over the years I’ve worked on a bunch of delicate and/or complex systems. I’d be more afraid of paint work than a full engine or automatic transmission rebuild lol
