I just got a 300ZX 3 days ago, and i want to make it faster, but i dont know quite what to do. It's a 88 two seater, with the nissan 3000 engin. i have exaust, intake, and tires. It is an automatic, but i have a friend that can do a switch for me for 300$. But if anybody has any ideas as of what to do with it to get it to go faster i would love your advice.
