GB's adapters for the Euro S2 and '80-'84 L-jet cars make for a nice workaround for running Bosch Type II injectors, high or low impedance. I think the L-jet will support most all injectors whereas the LH-jet in the S2 is limited to high impedance. Right?

There's a "joke" that Jim Bailey used to use, when he worked at 928 International. "You're $10,000 dollars away from having a $5,000 car."
Of course, years have passed since Jim blessed us with his presence at 928 International, and although that phrase still has about the same ratio, just with bigger numbers.

Thanks ptuomov. Finished by me but plated and mechanicals by our local maven worf928 with job-prolonging help from me. BTW: Your engine is pretty nice also.
To avoid fully hijacking the thread, I will offer some counter experience. I like the later cars better - my 91 S4 AT has a fantastic planted ride at speed, handling like it's on rails with the bigger rubber, and reliable enough to drive it anywhere. But it took a lot to get there, partially because the later cars have a greater number of expensive 'improvements' that can go wrong. Some of the ones I had to deal with that are not a problem on early/MT cars: Torque tube failure, LH and fan amp rebuilds, PSD maintenance, in-tank pump disintegration, twice as many valves to service, lots more electrical complexity, and rear A/C maintenance. Also can get bent valves from a timing belt failure The later cars have more power and comfort; the earlier cars (it is said) are simpler, lighter, and more hoonable.
If I did it again I would wait for one of the well known and well maintained Rennlister cars to come on the market, no matter what the model year. Someone sells a car with great repair records a few times a year. For example, Stan (MrMerlin) rehabs cars and sells one about annually on Bring A Trailer.

Um, what the heck is "F" guy? Did I miss something or what? Help me out here,I'm sure it won't change my life the smallest bit but I'm stumped.

A colloquial expressions "F*cking New Guy" aka FNG. I'm more stumped that this thread is still on-going from a 1-post/1st-post/only-post drive-by user.

Avoiding a money pit seems to fly in the face of the spirit of Porsche ownership, but realistically anytime you aren't going to a Dealership you are far ahead of the game.
Know what you want, buy that, don't try to make it.

@NoVector (and other contributors) That is an astute observation - wonder where the OP went? Should we keep this thread going? We've covered acronyms, L-jet injectors, Jim Bailey, engine refinishing, and some pretty interesting 928 economics re the original post (actually a pretty good discussion).

A fully optioned 81 is the way to go in my book. Sans sunroof of course 
It has the auto climate control of the later cars, but has a better routing of air compared to them. It also has a simpler vacuum routing compared to earlier and later cars.
And yes, high impedance injectors will work on a low impedance computer.
I've been running them in a 87 944 (similar to our L jet) without issue for a while now. Of course, with 6 holes per injector, atomization of the fuel is fantastic. The idle is much smoother.
The 81 also has the earlier brake system which is easier to upgrade to S4+ calipers compared to 82 and up systems. It also still has a diagonal brake circuit which got eliminated in 84 because of the optional ABS.
It is the year with the simplest electronics and vacuum system by far. It's dirt cheap to maintain compared to my 89, well, before the headgaskets went lol.
