I have a buddy who drives a 1990 Nissan 300zx N/A. Its a 5spd, and he has CAI and exhaust. And i have a 98' v6 stang 5spd..w/ just a CAI. I keep up with him pretty well off the line but he just takes me in top speed. What kind of mods would it take to take him down? Gears, a tune, exhaust, UD pulleys? Think that could do it? He's just really obsessed with his car and thinks its god or something so it'd be really sick to beat him so he would shut up about his amazing Z!!!!!!!
