the guys at ground zero are really cool but they're not exactly synonomous with high quality. granted, i do most of my shopping there but when it comes to something like a swap i would look into drag-tec. im not saying drag-tec is all that great, cuz i dont know for sure, ive just heard. but i would at least check it out. my friend got a b16 in his integra via gz and they screwed him on the price...but as far as i know they did a pretty good job.
basically you can ignore all i said, as long as you do your research.
