My previous EV used an Audi 5000 transmission. I pulled this motor (Warp11) and adapter out of that project and hoped that I might be able to salvage some of the pieces. Turns out that the mounting holes on the bell housing are very similar. Looks like I just need to enlarge a couple of the holes in the adapter plate and the bell housing will bolt right up. Then there is the small issue the distance between the bell housing face and the surface of the flywheel. Looks like I need to push the flywheel out about 5/8″ or shrink the adapter plate. Looks like it will be easier to add a spacer behind the flywheel and just get some longer bolts.
This is the custom aluminum flywheel I machined for my last EV build.
