For over 20 years, Australian Mazda performance power house Promaz, has specialised in everything rotary engine powered. From mild street engines to utterly wild race applications, Promaz also carries out complete driveline and EFI tuning upgrades. We caught up with the team while they were piecing together a very high output 3-rotor 20B engine capable of over 1500hp for Rowdys Garage.

  • Promaz and Pac Racing are probably the best for building aftermarket rotary engines from scratch and all have their unique philosophies in engine building, but the end results are both good. Great job guys. Nice to know if your OEM rotary engine blows up, there's still businesses building and manufacturing their own branded rotary engines and better than the OEM manufacturer.

  • A stress-free N/A 3 rotor was the engine the RX-8 should have had. 300-320HP stock and it would have been a fitting successor to the legendary RX-7.

  • I had a 1979 Rx-7, a 1981 Rx-7 and a 1985 Rx-7 with 90 to 120 horsepower engines. If I had 300-350 horsepower I wouldn't be typing now. Lol. Fun car great balance. 51 percent weight in front 49 percent in back. Great cornering and handling. Miss them very much. But I'm still alive.

  • get me out of ignorance, with this kit the wankel becomes more reliable? I understand that the rotary's Achilles heel is the seals and consequently they were very unreliable. The engine is supposed to be rebuilt every 30,000 km. is that so? thanks and greetings from Argentina

  • A rotary engine is just a modified wankel engine I would just like to get an efficient rotary that I can convert to multi fuels, H2 LP Actenlene, and regular fluids like gas diesel alcohol. I have already added H2/LP to my regular 4 cylinder jeep engine I had more problems getting the fuel filter through customs. Than actually converting the engine to multi fuel, right now I need a small hydrogen pump to pump the H2 in a storage tank. I don't need something huge just something that will fill an empty propane bottle for a camping stove. I have discovered that the computer adjusts my fuel flow once I open the LP/H2 line after starting. On highway I get roughly 75mph with a 1 gallon water tank, in town traffic seems cause engine overheat and just better to turn off the H2/LP? However I would like to get to the point where when the engine is running that my storage bottle and cell, is producing H2, but as I mentioned already I need a small pump to refill my bottle. Everything I have found is far too big to fit under the hood. Can anyone point me in the right direction for a small pump?

    • @Fullboost I always wondered how do you squeeze in the 3rd rotor , now I'm thinking you could butt-join two engines together and have a 4 rotor engine , I worked on rotary engines since early 80s , for some reason I've never warmed up to them , maybe it had to do with my diesel engine beginnings .
