Has anyone ever done a 13b-T swap on a miata? Any shops that can do it? How much would it cost? And last question what would I need?!?!

 

I don't know, try searching.

Of course.

A lot.

A Miata. A 13bt. Lots of money. And little sense :P

I know at least you aren't the only one who's ever considered this, so there's a good chance there's some research if not actual work done on this very thing. Best of luck to you.

 

IIRC, the firewall has to be modified to fir the bell housing and rear of the motor.

Maybe this will help

why build one when there is one for sale... im sure you could get this one for atleast 50 cents on the dollar for what it would cost to build your own

p.s. you might try searching, I am sure you will find a plethora of information... also try the miata forum

 

does that look like a 13bt to you!? yes I did search and yes I saw that car before...maybe you should learn how to read

 

Mazda Sport magazine had an article awhile back about someone with a 13bt in a Miata. Was a very nice and clean build. I believe the owner and builder for the car works for NASA. It's been awhile since I've read the article, though.
