The Racing Beat-designed and manufactured Peripheral Port Intake Manifold mates a Weber 48 IDA or 51 IDA downdraft carburetor, or equivalent throttle body, to the Racing Beat-manufactured 13B peripheral port housings. (This manifold cannot be used on the Mazda Factory Race MFR housings.) The steel tubing manifold is attached to the rotor housings with hoses that are included. A simple support bracket fabricated for your particular application, typically attached from the carburetor-manifold junction to the threaded bosses on top of the rotor housings, will complete the task.
