^that being said, a small inline four has a smaller size maf because less air is flowing through compared to a v6 z32, correct? The more air that the engine consumes generally means the engine should be at a higher hp... Like when you boost a small sr20, you grab a bigger maf, because more air flows... If you can support the horsepower, the q45 should be better, if not... You will lose low end torque because it's too big? I'm wondering.... I'm not to keen on the subject, that's why I asked epstein.. He could deff justify his answers
