I was thinking. That piece of crap is so light, and with a 13b (maybe even a 13b turbo) it would be pretty fast cause its a light bitch car.
Anyone know of any conversions. I searched yahoo a bit and didnt find too much. Would it fit? And what about the transmissions. I would think a miata would be FWD.

 

Just found http://www.realbig.com/miata/miata/1994-10/604.html
Are there any cars that 13B's or 20B's go into relatively easy.

You can drop a 20B into a 2nd gen RX-7 pretty easily. I've also seen it done in a 1st gen. I also saw somebody put a 20B in a 5 series BMW.

 

wow that's cool!..a 20B 5 series Bimmer. Do you think a 20B or 13B fit the 2002s????...

 

thanks plenty 13bace.
Any idea on the costs (besides engine) of plopping a 20b into a FC?

 

Mazda even put a rotary in a Miata. One testbed for the new Renisiss was a modified Miata. They let reporters drive it even! I hope Mazda builds a rotary Miata; Zoom Zoom Mmmmm

 

Node - I getting ready to put a 20b into my FD.
I image the costs are going to be about the same,
maybe a little less for hte FC. From what I understand, the 20b will fit easier into 1st or 2nd gens. 3rd gen will require more work. Pettit has developed a sub-frame for there 20b conversion in to FD. It can be bought for about $2k. They charge $40k complete job. I am expecting to spend about $20-$25K doing most of the labor myself. I think it also depends on if you rebuild the 20b and to what extent.

 

20bs are so sexy. Can I hump your leg?

 

A 13B should fit fine. A 20B may be tight, but if it can fit in a 1st gen it should fit a 2002. The 20B is about 7 inches longer than a 13B.

 

You can get a complete motor for $2500-4000. K2RD's mounts are $430. You'll also need an ECU and ignition parts, figure at least $2000 for that. If you use the stock turbos you'll have to make a custom exhaust. Otherwise you can just go single turbo with a custom manifold, etc. You'll also need a custom radiator and IC. You may want to get a coilover setup to help compensate for the added weight up front. I would say that if you're doing it yourself shoot for a minimum of $10,000; but expect it to cost more--say $15,000 to be safe. Everyone always talks about $30K+, but that's if a shop is reaming you, umm, I mean doing the job.

 

I'll be trying a 20B after my wallet recovers from my last project. That may take a while. I don't think it should cost me more than about $10K, but I'll be doing EVERYTHING by myself.

 

CHECKPOINT in sacramento has a rotary in a miata....13.1s SUPPOSEDLY on street or drag radials.....12s with slicks.....DONT know the WHOLE story behind it but ive seen it and the bov sounds super nice on it.....

 

thanks alot ace, and good luck on your swap

 

You're welcome. I don't really need luck, just money!

 

Go for something that is lighter than a Miata
RX-Midget, 1500 lbs ready to run with approx 200 hp on tap from a street-ported 13B N/A

 

The Miata is RWD. If you're using a 13B you could use the transmission as well. You'll just need to make your own driveshaft.

 

i personally think you fcan put almost any motor into any car as long as you got the "$$$$" i know easy swap's for t2 motors. don't know too much on the cosmo. i have put a 13b turbo into a 1st gen. and also a 13b turbo into a '72 datsun 510. those where pretty fun. and yes it is the driveshaft that makes the conversion a pain in the *** but in the end it is all worth it

 

Japanese mini car enthusiast told me people have put rotories in Subaru 360s over there! Thats a 800-1000lb rear engine car, if it could hook up it would wheelie like Eddi Bellows Porsche 911...
I would like to do that to a Subaru 360 or Fiat 500.

 

you wanna talk about crazy engine swaps? The hennesey shop in houston, you know, the one that turbocharges the Vipers? Well, they are putting a viper v10 in the back of a pt cruiser.

 

I will try and find the issue agian, but in the last few months turbo had an article on a miata with a 7 powerplant.

It was impressive, anyone else see it... had a couple super nice supra's... killer looks and obviously the power too.

 

Node, I seriously hope you are kidding. Most people that know **** about miatas can kick FC and sometimes FD ***. It isnt a peice of ****. Have you ever driven one. And second, why are you even thinking about it if it is just a light bitch car. Are you a bitch that wants a light car. Now if you are serious about making some HP in a miata go to www.miataforum.com Look in the power section. Dont act ignorant.

 

Actually a Miata is kinda fast , at stock.. But anyways, Mazdatrix did a conversion a while back, maybe 2 years or so?

 

One of the original prototypes for the Miata as well as a couple of M2 cars had rotaries in them, they had the RX5 name on them.
