Update on Tesla Motor Placement
Now that I have a design for the battery pack location in the DeLorean, I was able to find the final position for the motor. Previously the motor sat further forward (in the space once occupied by the transmission) and tipped nose down about 40 degrees. Now the motor will sit over the engine cradle with the transmission tipped nose down about 25 degrees. This lessens the angle on the half-shafts.

The motor mount at the side of the Tesla motor was removed and put aside to avoid obstruction. It will still be used, but a bracket will attached to the side of the motor to allow the rubber mount to move to a less awkward position.
The half shafts are 22in and 25in, so closer in length than previously, also removing the potential need for a lay shaft.
This creates some space in front of the motor which could accommodate a pump or other non-high voltage units.
The Chevy Spark EV battery pack will be split into 3 parts, front 2 modules, rear 2 modules, and controller neck. I'll be using the existing shell (carbon fiber) and metal supports, with modifications to maintain the waterproofing after splitting. The two front modules will sit behind the rear axle where belts, oil pan and exhaust used to be. The rear two modules will sit directly above the engine cradle and motor, in the location previously occupied by the intake manifold. The weight won't be quite as low or as central as I'd like, but it won't be all that far from the original DeLorean weight distribution.
I'm putting misc electronics and high voltage (ac compressor, dcdc, heater, chiller, etc.) in the prior fuel tank area. The layout will be serviceable from below by removing the fuel tank covering plate. I'll be adding a splash cover for the fuel tank area to allow any water to drain away.
