When you mention the 13B engine, you’re not just referring to a powerplant—you’re invoking a legacy. Born from Mazda’s proud rotary lineage, the 13B is one of the most iconic Wankel engines ever built. It powered generations of Mazda RX‑7s, proving that compact displacement combined with clever engineering could deliver jaw-dropping performance. Over the years, the 13B engine earned a reputation for its high‑revving nature, smooth power delivery, and exceptional potential for modification.

At All American Motors Hub, we embrace that heritage. Whether you’re restoring a classic RX‑7 to factory spec or building a modern street or track monster, our inventory of 13B engine parts and complete units is tailored to meet your needs. From rotor housings and apex seals to turbo kits and ECU systems, every component is carefully sourced and quality‑checked. We understand that with a 13B engine build, precision matters—clearances, tolerances, and balance are everything.

The beauty of the 13B is its compact packaging and power density. Twin-rotor design gives you an engine that can spin to high RPMs with relatively few moving parts. Enthusiasts love how easy it is to bolt on forced induction, whether turbo or supercharged, and still retain the responsive, free-revving character that defines a rotary. Many builders report that a properly tuned 13B engine can punch above its weight in horsepower-per-liter compared to conventional piston engines.
