Tonys M50 Swap Build Thread

[FishEye]

Alright... Its time to get started on this damn swap... I dont have everything ready but im already running into some problems and i need all the help i can get... A buddy of mine got a 1995 e34 525 that he wants to track. He wants to slam a s52 in there so the m50 in there has to go... I decided to take the m50 to put in my e30 so yeah. This weekend i pulled the motor out but noticed somethings that im a little confused about... Anyways pics will explain..


The donor: 1995 525i














Okay... So what i noticed was this throttle cable that was on the throttle body... It looked like a motor that controled the first throttle plate or something.. The connector of this motor is on the chassis side... Do i need this for the swap? Or should i grab a throttle body without it?










Also want to throw a shout out to Wh33Lhop for giving me tons of info on the swap! Hes a reall cool dude!


UPDATE: this motor is gone... I just picked up the same motor from a 94' 325i .

As far as I could tell that thing connected to your throttle body is some sort of choke. Mine was busted on my e36 parts car so I went without, had no problems.

im trying to make a BAR legal swap since i live in california... do you think they'll check for that? or should i find a throttle body without that choke?

Actually, is that the cruise control module? If it has a cable on it I'm willing to bet it is. Either way it shouldn't have any affect on BAR/smog/whatever.

Its not the cruise control for sure. It doesnt connect to the primary throttle plate... Just the one on the front.

its e34 traction control

Correct its for the traction control it is not needed you can delete it all together.

I'm watching this thread closely, I'm working a deal to get a 525i for this same swap....

Okay i been super fcking busy with work and life... But my tranny took a dump yesterday so its time to get serious with this swap... I updated the first post but ill mention it again... The m50 that i pulled from the E34 is gone... So i went out and pulled one from a 94' E36 325i... My question now is can i use the 5 speed tranny and driveshaft from the same e36 325i? I can find a ZF320 tranny but its going to be hard to find a freakin e30 M3 driveshaft... Looking for other options here... Currently out of a car so i needa get this done! Thanks in advance for helping

You can also use a e36 328i driveshaft, or a e36 m3 driveshaft being the 4 bolt style.

Also need a E30 CSB flipped backwards.
