Anyone here do this swap or have a write up or a good place to refer to. Definetly looking into doing this swap any info would be great!

I was really looking into this swap, and it's just not worth it. You'll get more power out of a BP swap (if you don't already have one) with a lot less money and hassle.

That being said, there's a guy in central Florida with a 13b swap in his NB and it took him a solid year of week-end tinkering.

So you want to do a 12a swap, not a 13b swap right?

I used to own a 1st gen RX-7 and I can say with full honesty the 12a can kiss my ass.

 

[snig]

the 12a is a pain in the ass, hope you like rebuilds.

 

[nwdrifter]

no s5 and convert to carb less wiring my friend has same setup except hes running turbo.

I say do it.. if you like messin with cars (which most of us should) then you should't mind some tinkering. Just make sure its not your daily driver. If your planning on having it any time soon and having it reliable on a daily basis, forget about it.

I'm looking into doing a s5 swap also. You'll get the usual "use a search under rotary" on miata.net. If you can do the work yourself it's fairly cost effective. Use a TII transmission and diff. if you plan to go high hp.
Use a s3 oil pan backwards and a s3 front cover. The big concern is getting the transmission level with the diff. You may have to notch the front k frame also but it will fit and line up without any firewall or tunnel cutting.
Turbo requires more work to fit in all the turbo goodies.
But an NA with a bridgeport, carb and headers will get close to 300hp and weigh about 60lbs. less than bp.

Here's an old article on one of the 13bt MX-5s in our club.

I'd like to know how you get in and out of the driver's seat with those high diagonal bars and OEM steering wheel.

Easy. Left hand on top of windshield, right hand on rollbar, jump! I do it all the time, don't even have to open the door

Not really correct, if it's the car I'm thinking of....

This NB from FL was used by a company (Rotary Miata - web site is dead) as the development mule for a 13b swap kit. I don't know if the kit was ever sold.
The car was under construction for about a year, but not really weekend tinkering.
It had evidently been finished right befor MATG in '04. The owner had put on a big fart-can muffler and it sounded amazing!!

I'd love to get a trashed 90 or 91, flare it and put in a 13b turbo. That would be fun!

The guy I know has a FMIC on his 13b. I fell out of touch with him though.
