M52B25 (from E39!) into 316i
 

Hi everyone,
I have a few questions regarding the swap.
I want to swap M52B25 from E39 (single VANOS) to E36 compact with M43B19 engine currently in it.
I still haven't bought the M52 because a friend told me you need to change multiple things on the engine to fit (alternator, engine mounts, engine loom from E36....). The swap should be perfect since I will be taking the car to the MOT certificate (Croatia; also called atest), the OBDII and everything should be in working order.
Does anyone have a list of everything I should know/consider before doing the swap or even buying the engine?
Thanks in advance!
