thanks ted!

Those pictures are of a streetport

 

thnkx! How much does it run to get this done and by whom?

 

generally a street port cost like 300-500 dollars there are several companys, atkins rotary ?, pineapple racing?? , many more i cant think of any names off the top of my head...... however you have to totally tear downt he block to do it.....ie a rebuild, that iwll cost anywhere from 1000-2000, which if you have a very healthy or relitivly new motor it wouldnt be very cost effective...

but if your motor has like 150K on it or seems worn out getting a rebuild might not be a bad idea anyway, if you have the cash!, then get the porting done when your having it rebuilt

to tell how worn out your motor is, get your motor compression tested by a knowlegable mechanic who knows something about rotarys, or have mazda dealer do the offical test....
