Sidedraft Carburetor

(Weber 40mm)

The Weber 40mm, sidedraft intake system, is an excellent performance upgrade for your 20R and 22R. The venerable DCOE is Weber's premier carburetor and is the standard by which all other carburetors are measured. It is unprecedented for full-race use, yet its infinite tuneability by way of interchangeable calibrated parts allows it to be tailored to suit any engine and application. Hardly enough can be said about the DCOE. A low-pressure fuel pump is required (not supplied) if the Weber system is being installed in a formerly fuel injected car. We recommend the 40mm carbs for engines up to 160hp. For engines from 160-220hp, use the 45mm carbs, and for anything more than 220hp use the 48mm carbs. This is one carb only, air filters, manifold, and linkage sold separately.
