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 may have it! We'll ship it to you or come by the shop and pick it up.
The Rotary Doctor is a family-owned and family-operated business. We started rebuilding rotary engines in 1971!
