Holley Intake Kit

Production Note:
Status - Manufacturing Hold
April 2020

After decades of supplying us with a special version of their 465 CFM carburetor Holley has recently discontinued production of this part. This carburetor was used in several of our stock (non-ported) and street-port 12A and 13B intake kits. Holley has supplied us was an alternative model to consider, we're currently reviewing this version as a potential replacement. Hopefully this will be a suitable alternative, we'll update this listing when we have further information.

We offer the extremely popular Racing Beat-modified High Performance Holley Intake System Kit for 1976-1985 12A Stock (non-ported) engines.

Racing Beat's High Performance Holley Intake System Kit has proven over the years to be an extremely reliable carburetor upgrade, with very "streetable" engine smoothness and drivability characteristics. Fuel economy is comparable to the stock carburetor under similar driving conditions.

Complete Ready-to-Install Kit
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.

Rotary-tuned By Racing Beat
The heart of each intake system is a performance-proven 4-barrel 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. Each application has been fully developed and tested on our in-house dyno facility to ensure maximum performance.

Each comprehensive package includes a Racing Beat cast-aluminum high-rise intake manifold with a vacuum source for power brakes, a Racing Beat-modified Holley carburetor (465 CFM), foam air cleaner and canister assembly, throttle and metering oil pump linkages, and appropriate gaskets. All emissions control fittings are eliminated. This carburetor includes a vacuum-operated choke.

When installed on a 1976-78 RX-3 or a 1979-85 RX-7 12A engine, this kit increases engine output by approximately 20 HP with the stock exhaust system. However, for increased performance gains we strongly recommend the installation of an exhaust header/presilencer/Power Pulse Muffler combo (10+ HP) or an open exhaust (15+ HP) - resulting in total performance gains of between 30-35 HP depending on your specific intake/exhaust configuration..

The carburetors and manifolds used in these Holley kits are also available separately in the "Holley Components" section.

Note: Installation of this kit requires use of a high performance fuel pump delivering 6 psi @ 20 gph.
