And another M30 swap begins

[E30 Beast]

dont go and get just "ANY" m30 harness. Make sure it is from an e32 or e34 its what you need. The early harness will not work with a b35 ecu or some of the sensors like the crank reference sensor and temp gauge sensor.

plus the motronic 1.3 looks better and runs better

im running the late harness on my b34 and its great

why has no one said anything about the doors...

and how did you plumb your brake booster? I couldnt see in the pictures

alright still checking my options cause im low on funds and trying to find the cheapest way possible to do this, lol im suprised as much as u r on the whole lil door thing but now that u mentioned it im pretty sure someone's gonna talk shit lol

[E30 Beast]

quick question do i need to really cut the shifter arm that connects to the tranny or can i use a different one from another car

[LowR3V'in]

Sorry if I'm too lazy too look, but if you're
running a 260 w/ an aluminum holder use the 535 linkage.
OR you can put the selector from the m20 onto the m30 trans
and use the 325 linkage.

The difference is the size of the peg/hole of the gear selector on the trany.

hey everyone need some help tried starting the car the other day nd nothing, the starter,alternator, nd battery are good wut else should i check for

thanks guys Mark

[JoeMadoo]

ground wires, loose connections on the starter, alternator, and battery, main relay and connections, maybe ignition or neutral safety switch if you have one.

9/10 times it's something simple

[E30 Beast]

thanks joe will check nd see if that helps

[E30 Beast]

can the yoke on the back of the tranny be interchanged and by yoke i mean the tripod on the back of the tranny that connects to the flex disc

[LowR3V'in]

By looking at the part numbers, there seems to be two different sized output shafts
in the m30 trans. Make sure you have the right size/year.

The larger m20 output flange uses the the same part number
the m30 trans in the e34 uses. So I'm guessing one could use the smaller flange going
by that if you have to e34 trans. But it's different for the e28 535i trans somehow.

What is the trans out of?

[E30 Beast]

I believe the transmission is out of an e28 535i (has the fins at the bottom)

[E30 Beast]

does anyone have pinouts for the c101 plug and wut do i do with this 8 pin plug located near the ecu harness

I haven't done my swap yet but you could spend $10 and buy Franks CD or download and have your own trouble shooting guide...he can send it via email too...
I have it and it is a great guide...
worth everybit of $10....

[Jean]

You don't need to do anything with that plug...ignore it.

Pin outs have been posted here many times....you do want to look at the ETM for YOUR specific model / year though.
