HOLLEY 13B 6-PORT, 84-92 (uses 600cfm carb.)

We offer a Racing Beat-engineered and modified Holley Carburetor Intake Kit for all 1984-92 13B Stock Port (non-ported) 6-Port engines. Racing Beat-Modified High Performance Holley Intake Systems, manufactured for more than 30 years, have established themselves as an ideal way to increase the horsepower output of the 13B rotary engine at a very economical price. This is especially advantageous when compared to the alternative: expensive replacement fuel injection systems with their required software, hardware, and increased complexity.

These carburetor intake kits are a popular and economical alternative for a failed fuel injection system on a stock engine. The complete kit includes an extensively modified 600 CFM Holley “Double Pumper” carburetor (mechanical secondary & manual choke), a Racing Beat cast aluminum intake manifold, the popular Racing Beat Power Pulse Air Filter Canister with filter, basic throttle and metering oil pump linkages (1984-88 applications), gaskets, and detailed installation instructions.

Tuned By Racing Beat
The delivered-new, Holley 600 CFM carburetor included in this kit has been extensively disassembled and re-built at the Racing Beat facility in order to optimize the power output for the 13B 6-port application. One of most significant benefits of our complete ready-to-go kit is that is takes all the guesswork, trial-and-error, and frustration out of attempting to assemble, let alone tune, 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 kit has been thoroughly developed and tested using our in-house engine dyno to ensure maximum performance for each specific engine application.

Depending on your application, you may need to fabricate or purchase specific components to complete installation for your particular application. We suggest you review the 18045 Holley 6PI Kit Instructions to review the installation process. This kit does not make provisions for the operation of the Mazda-installed cruise control unit.

Fuel Pump
You will need to purchase and install a fuel pump that provides a 6 PSI delivery with a minimum 20 GPH rating – selection will depend largely on installation location. The stock fuel pump unit is designed to provide high pressure (40+ PSI) for a fuel injected intake and is not compatible with this carburetor application. It is NOT recommended that a fuel regulator be used to reduce the stock fuel pump pressure to 6 PSI – the stock pump will fail. We recommend the Mallory 4070M fuel pump for this application.

1984-85 GSL-SE – The stock fuel pump on this chassis is externally mounted (outside of the fuel tank) and must be replaced with a suitable unit and the appropriate fuel line fittings.

1986-92 (All models) – The fuel pump on this chassis is mounted internally in the fuel tank. The pump must be replaced with an appropriate internally mounted unit, or an external pump configuration must be designed and fabricated. (Moderate fabrication skills are required for this conversion.)

Exhaust
Optimum performance from the installation of this kit requires that a performance exhaust system be installed on the vehicle. The following exhaust configurations are ranked in order of performance potential:

1. Long primary header – dual-tube connecting pipe – rear muffler(s). (i.e. Road/Race Exhaust System)
2. Streetable Header/Presilencer – y-pipe – rear mufflers.
3. Downpipe/Presilencer – y-pipe – rear mufflers.

This intake kit is not intended for use on applications that retain the catalytic converters and stock exhaust system. If the stock exhaust system is retained, horsepower, throttle response, and performance will be compromised.

HOLLEY CARBURETOR ONLY, 13B TURBO 600CFM RACING BEAT MODIFIED
Racing Beat Modified Holley Carburetor Only, All Turbo II 13B Street Port engines 87-92 (uses 600cfm carb.) For normally aspirated use, not designed for use with a turbo charger.

We offer the extremely popular Racing Beat-modified High Performance Holley carburetor for the 1987-91 RX-7 TURBO II 13B rotary engine, configured without a turbocharger, and ported with our streetport intake/exhaust templates. This carburetor body is the same modified component that is included in our complete Racing Beat-modified High Performance Holley Intake System Kit for the 1987-91 RX-7 TURBO II 13B rotary engine. Additionally, this modified carburetor includes a cold start choke feature; a float bowl connection for a mechanical Metering Oil Pump; and great top end power! We recommend the Mallory 4070M internally regulated pump (6 psi) for use with this carburetor, or you may source an equivalent unit locally (the MAZDA OEM fuel injection fuel pump should not be used with this kit). The optional air cleaner assembly and manifold shown are not included, but are available with the complete kit, or as separate items.

The heart of every RX-7 Holley intake kit is a Racing Beat-modified, performance-proven Holley carburetor. We start with brand new Holley carburetor bodies that are disassembled by Racing Beat’s carburetor technicians and extensively modified in-house for use with a designated rotary engine application–stock port, street port, or bridgeport. This process is not a simple “re-jetting” project, but rather a complex series of steps requiring machining, drilling, and reconfiguring of the carburetor body itself as well as the primary and secondary metering bodies, adjustment of the float bowls, and complete replacement and/or re-drilling of all jets. These modifications are the result of countless hours of engine dyno testing and real-world testing.

For optimum performance, combine this Holley carburetor with a matched Racing Beat intake manifold.

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.

HOLLEY 13B STREET PORT, 86-92 TURBO
HOLLEY 13B STREET PORT, 86-92 TURBO

Performance Features
The engine prepared by Racing Beat, in developing this kit, included the 1989-91 Non-Turbo Rotors, with the higher 9.7:1 compression ratio; however, there is little difference in peak horsepower between the lower compression Turbo II rotors and the higher compression Non Turbo Rotors. The use of the TURBO II rotors, and 1 to 2 degrees more advance, would give nearly the same horsepower output. Furthermore, we installed the 1981-85 electronic distributor and coils to dramatically simplify the ignition operation. Because the development engine was assembled with the Mazda OEM apex seals, we deliberately limited the engine to 8800 rpm. With the installation of either carbon or ceramic apex seals, race-clearanced and snap-ringed rotors, and increased bearing clearances, the engine would be capable of running up to 9300 rpm safely and still making excellent power at this level.

One of most significant benefits of our complete ready-to-go kit is that is takes all the guesswork, trial-and-error, and frustration out of attempting to assemble, let alone tune, 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.
