At the moment im just gathering information and parts to do the swap someday. Now that i got this thought i think i can read this somewhere but how different is m30 ac versus m20? Could i use m30 ac without too big modifications ?

Thanks for the info! I had a thought since i dont have abs module or pump that could i put in something like 525 abs pump and stuff ? ofcourse the module and pump needs to be from same car to work right.

Forgot to mention i also have the e34 brakebooster+cylinder, lowering springs on front(dont know about height, and rear i think i will try to get e28 shocks to fit since the ones that came with are kinda trash ones) and i have the engines harness and its ecu which im not quite sure about but i will find out and slap it here and i have a itch its motronic 1.3. And and and i think i should have mentioned it is m20b20 and not the 525e model. Edit: kind of missunderstood that question about ecu but anyways. I have motronic 1.3 (RealOEM). And as you can see, not too familiar with them

So i will be converting my m20 powered e28 to m30b35(from e34 92') but our mot needs abs to it so what im asking is what do i need to make abs work. My e28 will have e34 front/rear stuff so i can fit its abs sensors. I also need abs pump still but what abs pumps can i use? Do i need especially the 535 abs pump or can i use something like 525 farm(there is one locally). And something about wiring process would be nice too.

Not in my town haha also i was kind of surprised how clean this topic was so i wont make it much more dirty now but yeah, it will take some time until i get to put these pieces in to my e28 since it still needs litle welding etc.

Thats what i thought. Anyway i have full e34 suspension etc in one corner the reason for the abs conversion is cause of our mot or whatever it is in english i think i cant get it registered with m30b35 without abs.

Forgot that i posted here, but thanks for the answer! Also kind of dumb question but i will be trying to fit e34 brakes etc with e34 535i abs pump but tell for my dumb brain what i need since atm i think i need the abs pump, abs control box, wiring for abs sensors and sensors itself. Yes, i could just buy e28 ones but i like to go the hard way also if someone knows how to use google could snap me either some thread or wiring stuff for me and sorry since this kind of doesnt belong to this forum

Just curious since im going to go look for m30b35, what kind of drive shaft i need since i know neither e34 will work nor m20 one. So do i need somekind of custom made shaft or can i make one myself ?
