This guy must be clueless...

"all parts form 2000-2001 740is"

..."this m73 is from a 1989 750il"

Wow, confuse me more please.

"M73 v12 complete running engine from a 1989 750il"

I assume he mistyped it, should read 1999
That is a E38 750 engine room.

M73 is bigger, 5.4 Liter engine and HP is also more, 240 kW.
M70 has 220 KW.

that would be a nice upgrade for an old engine ... especially if you're buying it second hand from 1999 cars ... thats 9 - 10 years difference, but I guess if needs the DMEs with it to run, but how about the EML ? is it different too?

It is all different. I-bus system, and our cars still have the old wires for each connector.
All wiring looms in engine room, all control modules are different, and then is the question if the oil pans are too big.
I know it from one guy in Germany who installed an M62 4.4. litres engine in an E32. Needed quite a lot of mods.
