I always wondered why no company has just made the TB. intake systems, front cover etc and built one themselves...maybe they have.
there's enough pictures out there and it does not look all that complicatred.
probably famous last words of someone who tried lol

Mazda already has this on the new CX SUVs, longitudinal i6T with 8-speed multiclutch AT with integrated electric motor (no torque converter), they could offer it for a performance car and also they can design a manual with similar layout.
They had a similar system design in the 16X prototypes back when the RX-8 came out.
In the current 48V system the electric motor contributes 17 hp (12.4 kW / 17 PS) of power and 153 Nm (113 lb-ft) of torque, with a much smaller and lighter Li battery. This would work wonders for torque fill wherever the Rotary could use it.
Replace the i6 with a new Rotary and voila!
RX-VISION for top dog Rotary (400Z, Mustang GT, Supra, Corvette)
ICONIC SP for affordable option (FRS GT86 BRZ)
Back to reality, NONE of these will ever happen.

I think a generator could be a good application for a rotary, since the engine can operate in a narrow powerband without needing to have good throttle response or low-RPM manners. My main concern is how reliable they can make the rotary engine in a use case that may involve starting and immediately making a lot of power without much time to warm up, my best guess is they may use battery power to preheat the engine oil or coolant.

basically the whole system runs at a much lower temp, and then there is a lot of effort to keep the battery at the right temp
Tesla uses something called an Octovalve, its where the heat pumps and ac systems meet

I've spent some time learning about EVs lately, and the main problem as far as I can tell is battery technology. If you happen to find datalogs showing a Tesla doing a 1/4 mile pass, you'll usually find that the battery pack voltage is dropping by at least a few percent when the driver is at full throttle and then it recovers by that few percent again when there is less demand on the battery. You can see the same phenomenon on a regular 12V car battery, the voltage drops by quite a lot when the starter engages. For both the regular 12V battery and the EV's battery pack, voltage dropping means the motor could be making more power if the battery was magically better at delivering energy without internal losses, or if something else like a generator was supplementing the battery to power the motor. I suspect there is some combination of generator output and battery size that would make for a better sportscar than a battery-only EV, even if it's just getting similar performance with less weight and the ability to refill the gas tank in places where charging stations aren't available.

as for the rest of the car, i think probably too much time has passed for someone to put an effort into building a 787B replica. i remember in the 90s, a company called Dauer (sp?) built some Porsche 962s for the street. good times ....

Defined Autoworks acquired lots of bits for an RX-792P GTP car, just not the carbon chassis so they're modifying a tube frame (I think a Daytona Prototype).
