I found another nugget of gold in the junkyard. A 1995 AAZ with K03-003 and two stage injectors.
I found a B4 IDI wagon in the junkyard, and after what ended up being quite a battle, managed to persuade the yard owner not to crush it till I had time to yoink out the engine.
Today was the day, and yoink it, I did. (thanks for the help and truck, SMOKEYDUB)
Upon arrival at home, i connected some fuel and electrics (and an exhaust hose!) and tried to start it. I found that all four glowplugs were not lighting, for whatever reason, be it a broken wire in the harness, or that they are burnt out. So I grabbed my heat gun, aimed it into the turbo inlet and started cranking. After 4 rotations it started to cough, then fired up!
I immediated shut it down and went inside for my video camera.
Here's how it starts, coldsoaked to -5C (ignoring the 10 seconds it ran 5 mins before) cold start engaged, full throttle till it catches:

Pretty impressive!
Notice the test light winking out. That's connected to the upper oil pressure switch, which opens when the head sees full oil pressure.
I really only want serpentine belt system, and maybe the pump and related brackets.
I offer up for sale:
Complete engine, everything you see here minus the trans and clutch
$1000
-OR-
Basic engine, just what it takes to run. Includes pump, manifolds, turbo. no accessories
$800
-OR-
Long block, just the head/block assembly, includes valve cover and oil pan.
$600
If you can think of some other combination, I'm willing to consider.
Will consider trades on something(s) interesting.
I'm after old BMW stuff, also would love a complete 20B engine. (if you don't know, don't ask!)
Fine print: Solds as is. I don't know the KM's on this engine. After experiencing 1.9L torque you can never go back to 1.6L... Not responsible for sad, lonely, discarded 1.6L's.
