Bring your Mazda RX-8 back to life with a low-mileage JDM 13B-MSP RENESIS 6-Port rotary engine and automatic transmission package from J-Spec Auto Sports. Every engine and transmission assembly is imported directly from Japan, professionally inspected, and compression tested before shipment to help ensure dependable performance and long-term reliability.

Designed for the 2009–2011 Mazda RX-8 equipped with the 6-speed automatic transmission, this genuine OEM powertrain features Mazda’s advanced Series 2 RENESIS 13B-MSP rotary engine. The automatic version uses a 6-port intake design, Variable Induction System (VIS), and a 6-speed electronically controlled automatic transmission. It produces approximately 212 horsepower and 159 lb-ft of torque in factory configuration.

Whether your original engine has lost compression, experienced apex seal wear, flooded repeatedly, overheated, or suffered internal damage, this low-mileage JDM replacement offers an excellent OEM solution. Furthermore, purchasing the engine and transmission together helps simplify installation and ensures component compatibility.

Why Choose a Low-Mileage JDM RENESIS Engine?

Japan’s strict vehicle inspection program often results in vehicles being retired with relatively low mileage. Consequently, imported JDM rotary engines typically experience less wear than many comparable North American engines.

Additionally, choosing a genuine OEM Mazda engine preserves the smooth performance and responsiveness that made the RX-8 unique. Instead of rebuilding a severely worn rotary engine, many enthusiasts prefer a low-mileage JDM replacement because it delivers factory performance at a more affordable cost.

• Rotary compression test

• Side housing inspection
• Iron inspection
• Cooling passage inspection
• Oil metering system inspection

Important Compatibility Notice

This listing is for the Series 2 JDM 13B-MSP RENESIS 6-Port engine with matching automatic transmission. Mazda produced different rotary engine and transmission configurations based on production year, transmission type, emissions package, and market.

Therefore, we strongly recommend verifying your VIN before purchasing. Depending on your application, you may need to transfer your original wiring harness, ECU, sensors, emissions equipment, or accessories.

This package is designed for automatic transmission vehicles. It is not a direct replacement for manual-transmission RX-8 models without additional modifications. Community experience also indicates that Series 2 engines should be matched to Series 2 applications for the best compatibility.
