Welcome to the official web site for The Rotary Doctor located in beautiful southwest Missouri! 

We specialize in engine rebuilds with or without modifications, maintenance, diagnostics, parts and service for the Mazda RX-7 and RX-8. If you need a clutch replacement, brake work, a ported engine, or an A/C recharge, WE CAN DO IT! 

With more than a hundred RX-7 and RX-8 parts cars in stock, there is a good chance if you need a part, we will have it! We can ship it to you or come by the shop and pick it up. We also have Mazda OEM literature, owner's manuals, repair manuals and more. 
The Rotary Doctor is a family-owned and family-operated business. We started rebuilding rotary engines in 1971! 

Your satisfaction is our NUMBER ONE goal.  


Rotary Doctor now has an eBay shop with many parts ranging from 1979 interior door trim to RX-8's Owner's Manuals to RX-2 Emblems. New pieces are being listed daily and we're excited to share our rare collection of Rotary Powered parts with you.

Many parts are still on the several parts cars here at the shop so calling or emailing to find what we have is still a great way to get what you need.
