m50 into 1984 318i

[sacbmwdriver]

hi i have a 1984 318i and i want to do a m50 swap into it, i wanted to know what i can keep in my 318i and what i will need to swap an m50 in.

i know i need an 88+ 325i radiator, e36 engine mount arms, e28 535i/m5 mounts, different brake booster, red label dme, and the wiring harness, is there anything else i am missing? or will need?

i know i need a tranny, driveshaft, diff, but i will worry about what combo i will go with a bit later, i just want to focus on being able to swap an m50 in and gettin it to run/start.

thanks for your help.

wiring adapter which can be found on this forum.

Buy an engine out of a E36 sedan, then buy the oil pan. This is what I have done and the driveshaft works, transmission mount and transmission works and all you'll have to do is swap the pan and bolt on the e28 mounts. Engine in.

For the booster I used the lucas booster, I believe out of a 7-series???

e34 master cylinder, I think.. lol bought it as a package at a really good price. The only problem with this is you have to "T" your front brakes because it is a 2 line MC instead of the stock 3 line.

Other then that.....you're good. I probably missed but that is the majority of what you'll need.

what driveshaft and tranny did you use?

[JdmEuroNorth]

Stock E36 325I sedan transmission and driveshaft which came with the engine.

I just did this swap. The subframes are completely different from the 325i/e. Your going to need to swapout the whole front subframe otherwise the m50 will not sit properly as there are no mounting points for the engine mounts to shit.

Not true, this is a 1984 318i with completely stock subframe and m50 installed.

OK, I was worried I'd have to get a new subframe. My M50 project is an 84 318i, too.

Um, wut?

This is not true. I am finishing up my swap, and it all fits..

[sacbmwdriver]

Ok so you CAN fit m50 into stock 84 subframe then?

Everyone here who did or is in progress with m50 into 318i what brake booster did you use?

[JdmEuroNorth]

e32 lucas booster.

[6gen91]

Bahaha. When i did my swap, bunch of morrons told me the m50 wouldnt sit properly on my 318i subframe with an m10. So i went out and got myself an m20 subframe. Mah bad for the info, guess i wasted my money lmaooo

[sacbmwdriver]

e32 lucas booster.

what e32s do those come out of?

[JdmEuroNorth]

735i I think, I could be completely wrong.
