It is mounted transverse it's kind of set out in a way I can see it fitting in the 900 chassis ok. I haven't physically measured it, but I think it could drop in from eyeballing it.
But the big reason is that the Tesla units include the gear reduction to directly attach to the short axles. The 900 has a funny arrangement where the engine is part of a whole transaxle unit which sits on top of the transmission and oil pan, drives the transmission by a chain, and then the axles hang out the side of the unit. I think the Tesla units could drop right in there, just need new axles.
There's a couple Model S rear drive units hanging around in local classifieds. I've been tempted but I don't think I can justify spending $$ on yet another project I'd never finish.
The Tesla unit is offset transverse whereas the Eluminator is coaxial. Both are integrated drive units - electric motor and gearbox.
Telsa includes the inverter in the drive module; the Eluminator requires an external inverter, unfortunately.
Quite the missed opportunity, because it would be nearly drop-in if it included an inverter. That's what is so great about the Tesla module. You feed it power and CAN bus commands and boom, you've got torque.
Yep, and the Tesla units are also more compact and from looking at the Eluminator it doesn't attach directly to the short axles, would require some other gearbox attached, no?
I suspect the inverter was not released with it because there is IP there that they cannot give away / sell. Tesla wouldn't either, you can only get that drive unit by salvage.
