hey how are you doing? I just bought 1987 300zx v6 non turbo. I already put a k&n intake in it borla exhaust, bigger throttle body, racing clutch. I was curious to see if you had any more suggestions for my z. I would love to make it a posi rear and swap the gears. What rearend would you need for that? And are there any performance cams that are made for my z? Also any other nissan 300zx tricks to get my ride moving would be great! Thanks for your time. Justin
