About the RX-8 6-Speed Manual Transmission

The RX-8’s high-revving RENESIS rotary engine needs a gearbox with close ratios, and Mazda paired the six-port version with a six-speed manual derived from the Aisin-built units used in other Mazda models. The RX-8 6-speed manual transmission offers precise shifts and suits both street and track driving. It is also used by enthusiasts in Miata and rotary swap projects.

What to Confirm

• Your RX-8 model year and engine (six-port 13B-MSP).
• Clutch and flywheel compatibility.
• Shifter and driveshaft fitment.

Installation Tips

Use the recommended gear oil, inspect the clutch and pilot bearing, and check the shifter bushings. Early RX-8 six-speeds can wear synchros, so smooth shifting while cold helps longevity.

Who It Suits

RX-8 owners and Mazda enthusiasts building rotary or Miata swaps.

FAQ
