Tesla Powered BMW E31 8 Series

So some of you might already know about my E31 conversion as it's been going on 3 years now! Currently running a Siemens 1pv5135 motor and DIY inverter and 6 speed manual gearbox. Has been running very well the last few months but with the Tesla components becoming available and my work on the open source control boards progressing nicely I've decided to convert the E31. Again.

I had originally thought to use the small high efficiency drive unit but decided to go all in and put in the Large rear unit for 450hp+

Going to be getting some help and the use of a workshop and vehicle lift for the drive unit install as it will need some serious work done to the rear subframe and boot floor. Once the drive unit is in then I can start putting some batteries into that nice big empty engine compartment. Should make quite a fun car and test bed for the open source control board. Stay tuned

With all that power on tap ... are you going to put the EVTV Quaife limited slip differential into the Tesla Rear end or are you going to trust yourself to keep your pedal OFF the metal?

I'd go with the Quaife .. since I know my foot is heavy ...

Are you going to use the same style mounting as BMW does with the rear suspension? Was thinking it would be kinda cool if you could build a cage to hold the power unit, then the cage would use the factory suspension mounts (Including the bushings) , you'd be able to drop the whole power assembly as a unit, make it easy to fiddle with. I have a E46, 3 series ,, assuming the E31 is similar?

Put double A-arms on the cage for the suspension and use the stock BMW hubs?

Cheers,,, cool project!
