So I've managed to shove an absolutely monstrous electric motor into my 76 280z. This isn't my first electric Z car, but it's different from my first in just about every possible way. For comparison the motor on top is the size I put in my first one, and on the bottom is the motor I've got in my 76 now.

Previously I kept the stock 4 speed transmission and fabricated an adapter plate to mount the 8" kostov motor. This time I dropped the transmission entirely and went direct drive. That allowed me to mount the motor deep into the transmission tunnel with just a little bit projecting into the engine bay.

I've completely blocked off the radiator opening with a steel sheet.

It's outfitted with high-output lithium batteries that are rated to 15C discharge which is 1,500 amps. Each one of those stacks of 4 batteries is ~65v fully charged and ~40v when empty. They're also rated to charge at up to 6C which would be a full charge in just 10 minutes.
The controller is a Soliton 1 that will do 1000 amps continuous at up to 310 volts. At full output thats 400HP but I'm running at a lower voltage than that. I've yet to turn up the power but preliminary testing shows it will break the tires loose on dry pavement even with my brakes dragging.
Though if I find one for sale I'd love to get my hands on a 3000 amps soliton shiva. That would take me from 500 ft-lbs to the diff up to 1,500 ft-lbs. The motor is capable of way more than what I'm feeding it now.
Now that the mechanical stuff is done I'll be pulling it all apart to paint the engine bay and battery racks. And I'm going to need to address my brakes and headlight/turn signal wiring before I can get it inspected and on the road. I'm definitely going to go with rear discs but I'm trying to decide between the maxima caliper/rotors or the wildwood setup.
