Second Hand Mazda RX-8 Engine Mount

Yes, engine mounts are a genuine part on the RX-8 — the rotary 13B-MSP Renesis engine is held in the engine bay by multiple rubber mounts, typically a nearside mount, an offside mount, and a rear torque mount or transmission mount. When ordering, identify which mount has failed, as each position is a different part number and not interchangeable with the others. Tell the breaker which position you need and confirm against your registration to be sure you get the right one.

The RX-8 ran as a single generation from 2003 to 2012, but received a significant facelift in 2009 that brought changes to various components, so a pre-facelift (2003–2008) mount and a post-facelift (2009–2012) mount may not be the same part. The engine code — 13B-MSP — remained consistent across both phases, which is a good sign for compatibility, but mounting and ancillary details can change at a facelift even when the engine does not. Confirm directly with the breaker whether the specific mount position you need crosses that 2009 boundary safely before buying.

It can do, particularly for the rear torque mount or transmission mount, which interfaces with the gearbox casing — the RX-8 was available with a six-speed manual or a four-speed automatic, and those units are physically different. The side engine mounts that attach to the block are less likely to vary by gearbox type, but it is still worth telling the breaker whether your car is manual or automatic when you request a quote. Supply your engine code and gearbox type together to avoid any mismatch.

Both the 189 PS (single-leading-plug, automatic-only) and 231 PS (twin-leading-plug, manual) versions of the RX-8 use the 13B-MSP engine code, so the core engine architecture is the same. However, the two states of tune were linked to different gearboxes and had some different ancillary configurations, so mount specifications could differ subtly between them. Confirm with the breaker by giving your exact registration or engine code so they can pull the right part for your specific variant.

No — trim level has no effect on engine mount fitment whatsoever. Trim variants like Standard, Evolve, R3, and Kuro differ in interior specification, alloy wheel style, and cosmetic features, not in how the engine is mounted. Any RX-8 with the same engine code, gearbox type, and production phase should use the same mounts regardless of which trim badge is on the car.

The single most useful thing you can supply is your engine code, which you can find on your V5C or via a VIN check — for almost all RX-8s this will be 13B-MSP, but having it confirmed removes any doubt. Also tell the breaker which mount position you need (nearside, offside, or rear/transmission) and whether your car has the manual or automatic gearbox. With that information, a good breaker can cross-reference the part accurately; never rely on year alone when ordering mechanical mounts.
