    Default E12 528i

    Just got hold of an old E12 528i 4 speed manual and i was wondering what type of gearbox it is? is it used in any other bmw's such as the E21? I'm assuming it will bolt up to a 3.5 M30?? don't worry, it's not going into a 5er, just a cheap project at the moment!

    Default The Original Fiver

    The Ole E12, Great bulletproof cars. I've owned three of them. Got both kids thru high school. Can't help you with the clutch because mine have all been slush boxes. Go to Firstfives.org for more info on the 3.5 conversion. You will find plenty. I never consider the swap myself, the 2.8 is more than enough in the lighter body plus the suspension will need to be brought up to snuff to really handle the extra power. For the money some spend to do it, I can get a nice used e30. When I want to go faster, I just crank up the 535i.

    It's a Getrag, Model 262 I believe. Same MT was used in Bavaria's, 3.0's, 530i's. I swapped the AT in my '80 528i with one. Clutch parts seem to be readily available in US. It should bolt to any M30, but it won't have the holes for the flywheel sensors the early DME's required.

    the housing of the tranny is the problem, you cant get a flywheel that fits the clutch harness.. I would tell you Rory to login to realoem.com and see the parts u need ... they will tell u which are still in use and which are discontinued.
