HOLLEY 13B STREET PORT, 4 PORT
We offer the popular Racing Beat-modified High Performance Holley Intake System Kit for the 1974-1985 13B 4 Port Street Port engine.
Racing Beat’s Holley Intake Kit for the 13B 4 Port Street Port engine has proven over the years to be an extremely reliable carburetor upgrade, with very “streetable” engine smoothness and drivability characteristics. The Street Port Holley Kit includes the same basic components as our non-ported engine Holley Kits; however, the specific modifications to the carburetors are significantly different. The carburetor used for the 13B 4 Port Street Port applications features a larger 600 CFM model utilizing a mechanical choke and mechanical secondaries.
One of most significant benefits of this complete ready-to-go kit is that is takes all the guesswork, trial-and-error, and frustration out of attempting to assembly your own intake kit! We’ve taken over 40 years of our rotary engine experience and know-how and combined it for you in this complete, ready-to-install kit. Our intake kits has been thoroughly developed and tested using our in-house engine dyno to ensure maximum performance for each specific engine application.
The heart of each intake system is a performance-proven Holley carburetor. Depending on the requirements of each specific application, the carburetor is disassembled by Racing Beat’s carburetor technicians then reworked, retuned, and reconfigured specifically for use with a designated rotary engine application. This process is not a simple “re-jetting” project, but a complex series of steps requiring machining, drilling and reconfiguring of the main and metering bodies, adjustment of the float bowls, and complete replacement of all jets.
Headers must be used with these street port intake systems to achieve maximum horsepower gains.
Note: Installation of this kit requires use of a high performance fuel pump delivering 6 psi @ 20 gph.

AIR FILTER HOUSING, RACING BEAT HOLLEY WITHOUT FILTER
Racing Beat Air Filter Housing Without Filter for Racing Beat Holley Carburetor
Racing Beat’s dyno-proven Power Pulse Air Filter Assembly, for the Holley Carburetor, is designed specifically for performance. While the assembly uses the same Racing Beat foam air filter element that fits the stock canister, the design of the Power Pulse canister both improves air flow into the carburetor and limits the introduction of dirt particles into the filter element. The spun aluminum canister pieces are powder-coated white for added durability.
The Power Pulse Air Filter Assembly fits most Holley 465, 550, 600, and 650 CFM carburetors (specifically, all Racing Beat Holley Intake System Kits). There is no provision for emission control valve hose/air pump hose connections on this assembly; however, there is a position available to connect a crankcase breather tube if needed.

MANIFOLD HOLLEY, 84-92 6-PORT ALL
Holley Manifold, 84-92 13B 6-Port All
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 when using this manifold with the 1984-5 13B 6-Port engine configuration.
All of Racing Beat’s 13B intake manifolds for Holley carburetor applications are sand-cast by a local foundries and delivered to our in-house production shop for all machining and surface finishing processes. Select manifolds are then hand-ported to match a specific intake port configuration for an intended 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 then surface finished using a ball-burnishing process that enhances the final appearance of the aluminum material. Once these labor-intensive processes have been completed these manifolds look as good as they perform!
If needed, an engine-to-manifold gasket (1984-85), (1986-88), or (1989-92), and/or Holley base gasket are available separately.
