ok,well i remmebr in one of my sport compact cars a while ago ,PJ boifacio had a miata with a rx7 engine in it...does anyone know what is needed to do this,like does anyone know anyone who did it..obviously thares gunna be needed motor mounts,but besides that i need help and stuff,thanx!

 

racing beat did it and said it wasnt worth the effort considering how much power can come from a miata with a big single turbo. Heck one single turbo here on a stock miata engine is supposed to run 11's. Anyway here is some info for you:

that should be enough to get started

 

hey thanx,well apparently if i wanna buy a kit,is gunna cost me 15k...ill stick with an rx7..i could get a much better car for 15k invested into it.well that was worthless

 

I saw one at the Rspeed (performance shop for miatas and minis) open house yester day. It was so cool, so loud, and did I mention that it had 300 bhp.
It was an 89 Turbo II engine transmission and diff. just bolted in with alittle cutting. Which I think he said that the mazsport kit comes with one that is precut.
He also said that the miata drivetrain is strong enough and it can just bolt to a 13b engine (NA of course). His car had about $15k in it and took 1 yr to do, it was mazsports first wankel miata. It acually lightened the miata by 35 Lbs (which is acually alot for a 2100 Lb car). If the stupid boinger (reciprocating engine) in my miata right know dies I will put a 13b in the car.
