i have been debating on swapping a m30 into my e30 and i have been hearing some things. that they have problems with overheating and i think i read somewhere that they dont use alot of the same swap parts as you would with a 24v swap and that the electrical is a pain. i plan on using a m30b35.can anybody help me out with this or give me some suggestions or things to watch out for? thanks for the help
