Wait by quad turbo we're talking a turbo per housing right? Damn that sounds intense. IMO putting a rotary in a 240sx should be outlawed as they are the most ricer car on the road. Come on we gotta maintain our pride!! I was reading that 787B engine put out around 700hp but ofcourse thats racing tuned, what can you get out of a street legal?

That would be no better than two small turbos in a 2 rotor car. Nobody does that. Why not two large turbos in a 4 rotor car?

Nice. I'm getting rusty. Shows that I don't follow the Bugatti all that well.

Sounds kinda out there but I'm thinking turbo hayabusa into my '83 eventually. Only of something bad happens to the 12a.

Actually, IIRC the R26B made closer to 900 HP at 10.5K, but was limited to 9K for the race, which put the peak output at around 700. Mazda later found out that wasn't really necessary and they could have easily increased the RPM limit for the entire race. But the R26B is also a very special engine, much more than the custom 4-rotor engines out there. Practically, you're looking at 550-600 HP on an NA peripheral-port made with 13B parts.

For a side-port 13B-based street engine, I'd wager you'd see around 350 HP NA with a moderate streetport, but we don't actually know since to my knowledge no one has ever built a side-port 4-rotor from Mazda parts.

Well, FD owners do, and look where that got them.

Appropriately sized twin turbos on a 4-rotor would spool plenty fast. Four would just be needlessly complicated and expensive and difficult to set up.

Interestingly enough, I was watching something on Ed Cole, the father of the small block chevy v8. In 72 he is the one of the engineers who had designed and built the prototype rotary powered corvette. It was a 2 rotor that made between 180-250 hp at 292.5 cid.. THat was not enough so they made a 4 rotor version by joining two of the 292's together for a 4 rotor at 585cid with almost 420hp.

The looming gas crunch of the 70's, as well as the high sales volume of the current corvettel platform canned the whole idea.
