I have a B18C GSR engine in my civic and I live in California. I got the the setup BAR'd a while back but now interested in getting a little more power while staying BAR'd. I know I can't do much but what options are available if any? I'm thinking of getting CARB legal parts; intake manifold, intake, cams, adjustable cam gears. I know they won't make any power gains without a proper tune. Is a tune possible while allowing me to stay California legal or will I be wasting my time and money?
