W123 with a 2.6 M103?
 

Has it ever been done before. I was planning on selling my M103 with what I guess might be 209K miles on it (that's what the odometer says but it runs well) but my dad likes the idea of putting it in his 240D, which has a blown engine. He also informed me of something last night that my mechanic didn't tell me when I talked to him, my mechanic did a compression test and it had good compression in all cylinders. I figure why not, I have most of the parts I would need if it is a straight forward swap. I could use the automatic but my dad wants a manual (gotta use a w124 or w201 manual).
Has anyone here done this swap before or know of someone who has?

all you need is wiring. Lots of wiring. Factory wiring is available if you've got the original car handy. Megasquirt is an option.

There's a thread around someplace about a fellow putting an alloy M117 into a W123 and how he handled the wiring issues.
