Holley Intake Kit

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.

The carburetors and manifolds used in these Holley kits are also available separately in the "Holley Components" section. Also see the "Intake" section for other related intake components.

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