Adapter Plates

Racing Beat offers the RX-8 Renesis Engine Carburetor/Manifold Adapter Plate for the 2004-2010 RX-8 Renesis (Six Port - High Power) Engine.

The Carburetor/Manifold Adapter Plate is intended to adapt the Racing Beat-manufactured 1986-1991 Six Port Holley and Weber Downdraft Manifolds (Part Numbers 16476 and 16493 respectively) to the 2004 through 2010 RX-8 Renesis Engine.

As delivered, the adapter plate has been ported to match the Renesis engine with the Six Port sleeves removed. The Mazda Factory RX-8 Renesis engine-to-intake multi-layer manifold gasket is utilized with the adapter plate; however, the gasket is modified by drilling out the rivets that secure the multi-layer gasket. The two (2) gasket layers that are normally nearest the engine block are then used between the adapter and the engine block. The Mazda Factory 1986-88 or 1989-92 multi-layer gasket is utilized between the adapter plate depending upon your choice of Racing Beat Downdraft manifolds.
