This will fit earlier engines as well.

This bolts to the top two transmission bolts holes closest together on the intake side of the rear cast iron.

One side is fits the non-turbo teeth on the flywheel, flip it over to use the other teeth for the turbo flywheel.

This will not fit automatic Rx8 engines, unless maybe you used a huge stack of washers to line up the teeth, or got creative with the spacer; however this is not supported nor guaranteed to work.

Do not fit Rx8 Formula Mazda Flywheels.

    Very well made, nice protecting coating, works exactly as expected. Don't use the old "pressure plate bolt and a wrench" trick, the single 54 mm nut on rotary flywheels takes far too much torque. I broke a wrench and a bellhousing bolt before buying this.
