What engine does Mazda replace in an rx8?

The Mazda RX-8 is equipped with a unique rotary engine known as the Renesis engine, which is a variation of the Wankel rotary engine. If you're considering replacing the engine in an RX-8, you would typically look for another Renesis engine, as it is specifically designed for that model. However, some enthusiasts may opt for aftermarket rotary engines or even conversions to different engine types, but these modifications can significantly alter the vehicle's performance and characteristics.
