justin,

almost everything you want to know about this swap is to be found at www.firstfives.org. go to the technical faq section and read the faq on 2.8 to 3.5 l swaps. it covers motronic and a host of other issues. i'm currently doing this (fi is off and the engine is almost ready to come out) so let me know if you have any questions.

GREETINGS, I'M CURRENTLY SWAPPING AN ENGINE IN MY 1979 733I MANUAL WITH AN ENGINE FROM A 1982 735. HAVING ESTABLISHED THAT I WON'T ENCOUNTER ANY MAJOR MOUNTING ISSUES IT HAS BEEN BROUGHT TO MY ATTENTION THE MOTRONIC/PRE-MOTRONIC PROBLEMS I COULD RUN INTO. I HAVE HEARD BMW WENT MOTRONIC DURING 1982 IS THIS TRUE AND IF SO DOES ANYONE KNOW OF ENGINE NUMBERS SO I CAN IDENTIFY IF I HAVE A MOTRONIC ENGINE. IF MY ENGINE WAS MOTRONIC AND I WANTED TO USE MY EXISTING FUEL INJECTION SETUP DO I HAVE TO CHANGE MY CAMSHAFT OR ANYTHING ELSE ? THANKS IN ADVANCE.
PS- THANKS TOM AND MIKE W FOR YOUR ADVICE
