Weber Intake Manifold - 48/51 IDA Carburetor
1974-85 13B 4-Port Rotary Engines - All

The cast-aluminum Weber Intake Manifold is intended for use with a Weber 48 IDA or the Racing Beat-modified 51 IDA carburetor on a 1974-85 13B 4 Port intake engine. Although a 1984-85 13B 4-Port intake engine was never actually produced by Mazda, this engine configuration can be assembled using available parts. (1984-85 13B RX-7 engines were configured with 6-Port intakes.) Imported directly from Japan, these beautifully machined manifolds include the following:

Base gaskets - Qty 4
Phenolic Spacers - Qty 2
Carburetor mounting hardware - as shown

The Weber manifold is designed with three (3) vacuum source fittings. Two fittings on the intake runners are plugged with a metric pipe fitting, and can be easily tapped to American pipe sizes to accept various common fittings. If needed, an additional fitting (10mm X 1.25) can be used for power brakes.

If needed, these optional items are available separately:
Accelerator Cable Bell Crank
74-75 & 81-85 Manifold-to-Engine Gasket
76-80 Manifold to Engine Gasket
Intake Water O-Ring Gaskets
