Running an internal combustion engine?

When I watched a video on youtube one day, a video caught my eye. the name of the video is Sending RX7 to Rotary Hell. LOL Funny title, but it got me to thinking about trying to convert a Rotary engine to hydrogen. It may be easier, but it could also be more difficult because of the electronics that newer RX7s and RX8s have on them to precisely control fuel flow.

Hey, now that's an interesting idea. I used to own a '73 with the 12A motor, 4bbl carb. One plug fires before TDC, the other at TDC. You could probably drop the first one entirely. The only thing you couldn't do is replace the first plug with an injector. Unlike a 4-stroke that has an intake cycle, every time the rotor approaches the plugs it's in a compression cycle. Retreating from the plugs it's in a power cycle. There's no down time on the combustion side of the chamber. The rotor seals, side and apex, are made of carbon, or at least they were in '73 which may or may not hold up well to HHO.

Just my 2 cents.

Yeah ZFF, there's no telling how well the seals and the apex seals may hold up using hydrogen fuel.

Does anyone know how accurate this is:
