Comtemplating turning my wife's old clunker '87 GT into a street fighter. Does any know if it's smog legal to convert a Speed Density car to Mass Air in th California? I don't have the slightest idea of where to look or who to ask.
go ahead and do it.itll be fine, epa mandates that the same year or newer engine has to replace the old one.your not replacing just adding upon the old one with a well know upgrade, you would be helping your emissions.and like he said before cali wa the first state to have maf on mustangs.youll be fine.
