hey, i'm new to this forum thing, but a couple of my buddies told me that they are extreamly helpful with different peoples knowledge on volswagens. i have a 2000 12V VR6 jetta auto tranny, with a custom cold air, and a borla cat back exhaust. i want to keep moding my car and hopefully boost it with either a SC or a turbo. i want to do some things before that though like bigger cams, and a new head. any advise on these things pos or neg would be very helpful, also any type of advise on maybe something else that would help my preformance. thanks
