if you read my posts then you would know, replacing the carb with a weber is the only way to get rid of the vacuum lines. Its not emissions equipment, its the feedback system for different load and driving conditions, and removing that stuff from the stock carb will make it rich and generally RLS.
The weber 32/36 is the general replacement. You can do a holley 5200 but it doesnt save much money if you value your time at all, because you have to piece together all the mounting and make a throttle bracket. There is a smaller version made now. Dont get a 38dges, you will be wasting your money becase a) mazdas arent fast to begin with and b) replacing the carb will not make a mazda fast.
anyway. if you have more pointed questions, just ask!
