Choosing the right used Mazda RX-8 timing chain
Used timing chains vary between vehicles - and whether you call it used, second hand or a replacement, matching the right one matters. These are the details breakers need to match the right part to your car - our request form asks them so you only hear from suppliers with the correct part:
- State whether it's petrol or diesel
- State the engine code if known

Fitment questions
Does the Mazda RX-8 actually have a timing chain?
No — the RX-8 uses a rotary Wankel engine (the Renesis 13B-MSP), which has no camshaft, valves, or timing chain; instead it uses an eccentric shaft and apex seals to control the combustion cycle. If you are searching for a timing chain for an RX-8, this part simply does not exist on this vehicle. You may be thinking of the eccentric shaft, the oil metering pump drive, or perhaps confusing it with a piston-engined Mazda such as the 6 or 3.
What is the equivalent of a timing chain on the RX-8 — what part controls engine timing?
On the RX-8's rotary engine the eccentric shaft (sometimes called the e-shaft) performs the role that a crankshaft and timing chain assembly would in a conventional piston engine, transferring the rotational force produced by the rotors. There is no chain, belt, or sprocket set to replace in the conventional sense. If you are chasing an oil metering pump, eccentric shaft, or rotor assembly, search for those specific parts and quote your engine code (13B-MSP) to the breaker.
I've been told my RX-8 needs a 'timing' repair — could it be something other than a timing chain?
Almost certainly yes — because there is no timing chain on the RX-8, a workshop referring to 'timing' work is most likely talking about the ignition timing, the eccentric shaft position sensor, the oil metering pump, or a full engine rebuild due to apex seal wear. Rotary engines are sensitive to compression and oil supply, so these are far more common failure points than anything chain-related. Describe the exact fault or part number to a rotary-specialist breaker so they can identify the correct component.
Does it matter which year RX-8 the eccentric shaft or engine parts come from — are early and late cars the same?
The RX-8 was produced from 2003 to 2012, with a facelift in 2008 that introduced the Series 2 (also known as the Type S in some markets); some internal engine tolerances and ancillary components were revised between Series 1 and Series 2 cars. The engine code (13B-MSP) remained consistent across the full run, but you should always confirm the exact build date and any part numbers with the breaker against your registration before buying engine internals. Rotary-specialist breakers will often know which sub-variants interchange and which do not.
Does the RX-8 trim level — such as PZ, Kuro, or R3 — affect which engine parts I need?
No — trim levels on the RX-8 (including PZ, Kuro, and the R3) are cosmetic or suspension/brake-spec distinctions and do not change the engine; all UK RX-8 models share the naturally aspirated 13B-MSP rotary engine. Engine internals and ancillary drive components are determined by the engine code and build year, not by the trim badge. Simply supply your registration or engine code to the breaker and they will identify the correct parts regardless of which trim your car is.
Could a timing chain from another Mazda model fit the RX-8?
No — the RX-8's rotary engine is architecturally incompatible with conventional piston-engine components from other Mazda models such as the 6 or 626, which do use timing chains or belts. There are no shared internal drive components between the rotary Renesis engine and Mazda's piston engines. If you need rotary engine components, source them specifically from an RX-8 or RX-7 specialist breaker who understands the eccentric shaft, rotor, and apex seal architecture.
