HOLLEY CARBURETOR ONLY, 13B TURBO 600CFM RACING BEAT MODIFIED

SKU: 16629

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.
