Re: Help with webber upgrades?
Set the float to 41 & 50mm . With the adapter plates on, cut out the entire area under the plates in the manifold . You will be removing an "X" . After that is cut out and blended in, remove the adapter plates, and flow the area from the top on into the plenum as smooth as possible. Don't worry about sanding it dead smooth, as it will help to atomize the fuel. If you don't have to worry about passing emissions, tap the two holes behind the egr valve with a 1/4" pipe tap, and cap the holes off with a pair of brass plugs. You can get a nice fuel pressure regulator from Napa , use one with 1/4" fittings. The output end of the stock fuel pump can be cut off to eliminate the restriction where the line output goes to 3/16", this helps a lot with high rpm flow probs. If you don't feel comfortable doing the carb mods and intake , I do set them up for people....
