  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. Our intake kit has been thoroughly developed and tested using our in-house engine dyno to ensure maximum performance for each specific engine application.

  Complete Kit
  The heart of every RX-7 Holley intake kit is a Racing Beat-modified, performance-proven Holley 600 CFM Double-Pumper 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. 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.

  Every RX-7 Holley intake kit includes a Racing Beat cast-aluminum high-rise intake manifold with a vacuum source for power brakes, a Racing Beat-modified Holley carburetor, foam air cleaner, and canister assembly, throttle and metering oil pump linkages, and appropriate gaskets. All emissions control fittings are eliminated.

  MANIFOLD HOLLEY, 13B 87-92 TURBO

  Holley Manifold, 13B 87-92 Turbo II

  The Racing Beat-designed intake manifold for the 1987-91 TURBO II 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 street and race applications.

  All of Racing Beat’s 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!

The optional air cleaner assembly and manifold shown are not included, but are available with the complete kit, or as separate items.

  Each carburetor is modified by Racing Beat to maximize the performance of a specific engine application. Every carburetor is disassembled, modified and reworked by a Racing Beat carburetor technician. These modifications are the results of countless hours of engine dyno testing and real-world testing. These extensive modifications are undertaken to increase the airflow to meet the demands of the rotary engine. Each finished carburetor is bench checked by chief engineer/engine builder Jim Mederer.

  This carburetor requires the use of a high performance fuel pump delivering 6 psi @ 20 gph, we suggest the use of the Mallory 4070M unit.

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