Racing Beat Holley Manifold
1984-92 13B 6-Port Engines


Production Status Update: Due to a COVID outbreak at the local foundry these 6-port manifold castings have been on an extended backorder since September 2020. Apparently the local shop was hard hit by the virus and they subsequently lost several employees to attrition. We're pressing for updates, when we finally receive the manifold castings we'll start immediately on the machining process and should have them ready within just a few days. If you have an order already with Racing Beat you'll receive priority status in the allocation. Thanks for your patience!

The Racing Beat-designed intake manifold for the 1984-92 13B 6-Port rotary engine is ideally suited to meet the performance requirements of the Holley carburetor. Designed by Chief Engineer/Engine Builder Jim Mederer, these cast aluminum intake manifolds have proven themselves in a variety of RX-7 street or custom race applications.

Please note:  it is highly recommended that the intermediate housing be port-matched to the manifold (P/N 16476) when using this manifold with the 1984-5 13B 6-Port engine configuration.

All of Racing Beat's 13B aluminum intake manifolds for Holley carburetor applications are sand-cast by a local foundry and delivered to our in-house production shop for all machining and surface finishing processes. Each manifold is then hand-ported to match a specific intake port configuration for each specific engine application. Further machining is then undertaken to match the base-plate surface to the Holley carburetor base. These critical machining steps ensure a positive fitment between both the engine surface and the carburetor base. Every manifold is surface finished using a ball-burnishing process that enhances the final appearance of the aluminum material. 

If needed, an engine-to-manifold gasket (1984-85), (1986-88), or (1989-92), and/or Holley base gasket are available separately.
