There is more misinformation in this thread than in the Creation Museum.
An streetable NA 13B can make around 250-300 WHP, depending on what you're willing to live with. Although he has never released numbers Carlos Lopez builds NA 13Bs that trap over 250mph and maths all equate to over 400 WHP. There are plenty of 1000 WHP 13B drag cars on methanol. Rotaries can run on anything. There have been diesel rotaries developed by OEMs, and tinkerers alike. The IMSA FBs ran a kerosene and gasoline blend. Let's not forget the hydrogen Rx8s still running around Japan.
I have quite a few friends who make over 500 WHP on perfectly reliable 13Bs. My last engine build made 197WHP, NA. I averaged 24MPG with a 48 IDA carburetor, it saw 3 full auto cross seasons and over a dozen trips to the drag strip. I put over 50k miles on it. I sold it to a friend in 2012 and it's still running in his FB.
I've been building rotaries since the mid 90s, so I'm partial. Once my BRZ is paid off it will be getting a rotary.
