There have been a few over the years. Most using DC motors an lead acid batteries.
I did a quick search but could only find one thread:
https://www.rx7club.com/build-thread...build-1026188/
However I know I've seen more so perhaps some more extensive searching will turn them up.
There are a few RX-7s on the EV Album:

It would be a conversion.

It is a conversion, I'm using a DC motor, lithium batteries, trying to keep the weight down, I want it to be fun to drive.

Using a Warp9 motor from my truck project, controller is 1000 amp 360 volt unit, while not inexpensive, has a lot of programmable features. I planned on 190v @ 1000 amps.
I will be using a turbo car 5 speed transmission, hopefully it will take the HP I am hoping to see.

Any reason you're not going AC? Just cost?
And yes, a Warp 9 will have no issue shredding an NA RX-7 transmission as well as the differential. Should be able to break drivetrain components at will just putting the right foot down in 3rd gear from a dead stop.

While I am not hoping for part breakage, I am looking for fun factor, I can dial down the controller and keep it reasonable. I am not familiar with the insight batteries, but am thinking 100 to 130 AH at 156-192volts.
I know that another Mazda with dual warp 9 motors is running 9 sec in the 1/4, I don't have the bank for that kind of action, already looking expensive.
I am using DC over AC because I had the motor and other parts from unfinished truck project that stalled at the 18k battery purchase point. It was either change it up or go lead acid in the truck.

I tested the car today, works well, surprised that I got the traction, although still had wheelspin. I have a few issues with the brake calipers sticking.
I will see how long the NA differential lasts with 3 times the torque of the stock setup.
A few more details to address, but very close to done.

Way cool! You'll have to keep us up to date with your progress.
Maybe a comparison to the Tesla once it's going well?
Anyway, best of luck and keep a heavy duty set of rubber gloves in the car. Oh, don't forget the cutoff for the rescue first-responders if they should ever be needed. I'm just saying...
Are you doing anything with kinetic energy-recovery systems yet? (Brake/recharging.)

I need to get some gloves, but use a lot of insulated tools. I have a mechanical disconnect inside the car and another under the hood, although a good point on 1st responders, I need some signs to indicate where to find them.
As for the energy recovery, it is much easier with AC systems and my DC controller doesn't support it.

Awesome car! If you ever need help working on anything besides the motor, let me know! I also have a few buddies who are into rx7s who would be down to help or check out the car.
