Well, it is hard to take most of these 'swap' guys seriously when most of them have never done one on an RX8, or are in a perpetual state of 'R&D'.
They can say how great they are, and how they have all the answers and graphs but no real proof is ever offered other than they know a guy, or saw a car, or read about it somewhere.
Meanwhile all of us who are driving our 8s problem free are somehow clueless to how terrible our rotaries are.

Jesus that's a huge rotary, better have tons of torque with that volume. im trying to fill the thread up with lots of asshat comments bc I have so many pertaining to the rotary. I'm not trying to convince anyone in here about the superiority of the almighty piston. That's common knowledge. So how about them straight six swaps? I love a motor that nearly sticks out of my bumper.

I'm aware of the charts and yes that's impressive data. But it would only interest me if I were needing to run large generators, pumps or ships. But in, I don't know, a car? The concept of a power plant that only works well at high rpm doesn't work in street cars. If it did there would be many more cars produced with them. Not just concept cars

Define "high RPM"?
Most Honda engines are more 7,000rpm rev limits, several more than 8,000rpm
Quite a few sports cars are over 7,000rpm rev limits, including all of Mazda's sports cars since the 70s.
I believe all Subarus are over 7,000 rev limits as well. Plus all flat 6 Porsches, all Ferraris, all Lamborghini's, most Aston Martins, the new 2015 Mustang.
And that is before we get into bikes, which usually have rev limits FAR higher than even a rotary's, 11,000-15,000, or more, and it works really well for them and is popular.
You can get more power out of an engine the higher you rev it, so car manufacturers can downsize the engine and rev it more to get similar power numbers with lower cruising fuel mileage. It's the direction all car manufactures are already going.
I'd say that there is plenty of evidence that high reving works rather well...

tôrk/noun1. a twisting force that tends to cause rotation.
Kinda the definiton of rotary, too...
ro·ta·ryˈrōdərē/adjective (of motion) revolving around a center or axis; rotational.
Just saying. Torque is all my 8 has- low top speed, but it gets there very quickly.

I love rpm. I've owned dozens of bikes engine from a WR250X to a godawful Duc 1098. I'm also aware of higher rpm usually equalling more power. However the bikes 14k rpm revving bike is 500ish lbs with rider. A CBR1000RR makes far more relative torque than the RX8. However when the only place a motor works is high rpm then it kinda takes street duty off th table. Sure it will work but that's like the crazy people saying five point harnesses and door bars are what street cars have.

Wtf
Holy wow...
I wanted to punch my brain out of my head after like 8 comments.... I then proceeded to skip 5 pages of complete crap.
Swaps are not reliable? Anyone that says that is severely out of date on their beliefs.
A Ls swap done correctly will last way over 100k miles.
You have engine
You have transmission
You have drive shaft
You have wiring
You have mounts
You have modification to steering and pedals
You have exhaust and intake
If you make all proper welds. Don't hack job the wiring. Tighten every bolt correctly. Use anti sieze and loctite in their correct place. There shouldn't be any question to reliability.
In college the teachers called the rotary engine the "rockstar" it's high revving and fast to the grave.
No matter how much you do to that engine it will never be as reliable as a pushrod Ls engine.
My rotary isn't blown but it's close enough. Its apex seals went to **** right under 100k miles. It's been driven 5 miles in two years. It also had the bracket for the clutch pedal snap in half twice.
Botched swaps are unreliable.
