I am dropping a remanufactured B20A3 replacement engine in my '90 Prelude 2.0S but I am sick and tired of the dual Keihin carburetors this engine came with. Does anybody know how I can install two weber carbs in place of these old Keihins? Weber contacts? Part numbers? Cost? Any help would be greatly appreciated! works4us1@yahoo.com aka realdeals
