What's a relatively cheap and quick way to make my '98 V-6 go faster? Let me know.

 

sell it and get a z28 lol j/p but that would help umm..forced induction

 

There are no cheap ways to get signficant and reliable power increases with any engine. The less power you have to start with, the more work you need to do. A supercharger, done properly will do a good job in you engine, but it is expensive. Nitrous will be a cheap way of doing things, but only works until the tank is empty. Bolt ons, such as headers, cold air intakes, etc.., will allow to make more more power, but work much better when combined with internal mods. Basically, you get what you pay for.
