The quickest Miatas are all rotary powered, and rotaries have won many championships in several different sanctioned motorsports.

Nice car man, I myself am From Auburn.

Glorious. I'm planning on converting my Miata into a Dorito-powered unicorn eventually, as well. It seems like a great swap because of the light weight (bare long block is over a hundred pounds lighter than a B6 bare block), power potential, and the fact that a swap is easy as an RX-8 bellhousing, welding a mounting tab to the front of a V8R subframe, and having a custom exhaust made. Wiring up the Megasquirt is the fun part.

Mostly I'm just making this post so that in six years' time when I'm three years and $15,000 into the swap I can come back to this thread and rage at what a clueless ******* retard I was.

Always nice to see other CNY folks on the interwebs.


Rx8 bellhousing won't swap over to the stock Miata trans. Would need to use an s4 na bellhousing on the Miata trans and slightly shorten the input shaft.

I have actually exceeded the 15k mark with my last iteration of parts I ordered. However my build included alot of bells and whistles (single turbo swap on a 13B-REW, Link G4 ECU, stainless piping / exhaust, stainless AN lines, etc.). It can be done alot cheaper if going na, starting with a turbo 2, using the Miata transmission, and using a Megasquirt for the ECU.

I also have a site I built at: www.rotarymiata.com with links to builds across the internet if your looking for more info on the swap.

NA FC gearbox has a Miata 5 speed inside, RX-8 gearbox has a Miata 6 speed inside. If I buy a complete RX-8 6MT and just swap my NB1 6MT tailshaft onto it, I should be left with a transmission all ready to swap a BP into an RX-whatever. There's got to be at least one person in the entire world that would want to buy that, right?

My plan was to use a stock TII long block with an FB front housing and get everything running, then change things from there. From what I understand, the single turbo fits in a Miata without cutting the chassis.

Thanks for the link, I'll check it out.

LOL that's awesome. I had that URL back in 1998-2006ish. Chronicled the many revisions of my rotary miata. At one time that URL was the number one result for rotary miata searches on Google. Prolly should have sold it at that point

Glad you have it and are putting some good content up. Carry on!

Nice edit, I was about to say.. how did rotarymiata> ****.
So rotary still = block?
Haha there is a guy on here with an insane BPrx7 build. But the Miata transmission wouldn't hold well.

That's awesome! I did a DNS Lookup one day and saw it wasn't taken and said hell with it, might as well build a small site. When I started my build I found bits and pieces here and there around the web but nothing as in depth as I wanted all in one place. So figured I'd make the site into a resource for those thinking about swapping in a 13b.

So If you ever want to start making motor mounts let me know. I'd be interested in a set. I been thinking of doing a rotary miata as a side project. Bridgeport is ******* sex.

Well yeah... because that's just hilarious on multiple levels, and probably cheaper than sticking a brotary back in it.

My oh my how times change but things stay the same ... Fresh Frankenstein motor, fresh fuel system, and bigger turbo and I'm back in action:
