Awesome project! Out of curiosity, where are you located since you say you can have it street legal?
For the DME wiring, maybe you already know it, but check newtis.info and bimmercat.com, the first one has the repair instructions and wiring diagrams and the second one it's the online catalogue to se which parts are compatible with which model. It's what I used to gather infor for my swap (one a lot easier than yours, from M54B25 to M54B30).
Keep us updated!

I'm from Latvia. Yes, it will be road legal, I had to make a project to get a approval from authorities, bracket has been made by certified company. When the car will be ready I will have to pass government technical inspection, after that special a brake test on a track.

Buy new engine
Dump the old engine
… lots of magic and swearing
Results :thumbsup:

Seriously though; swapping the block is probably the easiest bit. All the electronics and system communications is what scares me most in such an undertaking. Impressive stuff this
