I live 10 minutes away from probably the best rotary tune shop on the east coast. They also do LS v8 swaps. Why would somebody ditch the rotary for a LS v8? Better fuel economy, reliability, larger aftermarket avaibility, more torque, the list goes on.

Seriously, anyone who goes rotary and still wants plenty of RELIABLE power is a big idiot.

I personally detest the way the 13b sounds. The 3 rotor sounds pretty awesome.

I've seen a white Miata drag car, I think it was on Vimeo...it was faster than the rotary one I just posted. It was a 2.0 4 cylinder if I remember with some huge turbo and an unheard of amount of boost. I don't care enough to find it, cause those cars are clearly for drag use only. Take a poll of every person that ditched the rotary and LS v8 swapped...I'm sure they have no regrets.

Ironically, the drag Miata you are referring to is about a mile from my house as the crow flies. If you go to dragtimes.com. there is a rotary Miata that holds the #1 spot. It is faster than the BP powered car you are referring to.
I talked to the owner of the white car about bringing it out sometime. He is just not ready to do so.

Australia/ New Zealand v the WORLD!! 
Oh Yeah.
Although I'm gonna pull the New Zealand wins v the world in this case... (just like the rugby
)
That 6 rotor was built only about 8.5 hours from my house (as the crow flys).

Since there's already LOTS of sr20 swapped Miatas too I guess we can count that out.
Nobody has swapped the 1L ecoboost turbo I3, I'm still waiting to see someone do that. With enough boost they can make the same 200hp as the sr20 so I'd go for that one OP. 200hp + 50mpg = winning

hey guys i have been thinking about this for quite a while and have been seriously thinking or doing the sr20 swap , does anyone know what mods are needed to make the sr20 fit into the miata, just take into consideration i am a qualified welder and mechanic so normal engine swaps and metal fabrication is like a walk in the park for me, but putting a SR into a miata is uncharted waters for me, this would be my 3rd different manufacture engine into a separate automobile company chassis, any help and guidelines would be awesome,

However, they're questions that CLEARLY have never been asked before! I can't believe nobody has ever thought of an SR20 swap before!

This is the best one. Much glorious noises. 6 rotor, P port. I want one in an RX3 with flares and massive tires.

That motor lives in an RX4. There's videos of it driving, as well as on the dyno.
Power. It makes it.

Yeah only like 815hp or something though... with like 40ftlbs of torque. I didnt post the dyno video because it sounds like crap with the exhaust pointed directly at a wall. And the track video is laughably bad.

On an easy break-in tune.
Not one person on this entire forum has any room to laugh at the torque that thing is making.
