Holley Intake Kit for 1984-92 13B 6-Port Engines
Racing Beat’s Holley Intake Systems, offered for more than 25 years, have established themselves as an ideal way to increase the horsepower output of a 12A or 13B rotary engine at a very economical price, this is especially advantageous when compared to the alternative: expensive fuel injection systems with their required software, hardware and increased complexity.
We offer a Racing Beat-engineered and modified Holley Carburetor Intake Kit for all 1984-92 13B 6-Port engines. These 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 carburetor (manual choke), a Racing Beat cast aluminum 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.
The Holley-supplied 600 CFM carburetor that is included in this kit has been disassembled and re-tuned at the Racing Beat facility to our specifications to optimize the power output for the 13B 6-port application. This carburetor features mechanical secondaries and a manual choke.
Depending on your application, you may need to fabricate or purchase specific components to complete installation for your particular application.
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.)
Manual Choke Mechanism - Installation of a manual choke can be accomplished using the Holley Choke Control Cable and In-car Mounting Bracket.
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. This kit does not make provisions for the operation of the Mazda-installed cruise control unit.
