I will be purchasing a 2000 Dodge Avenger this monday(hopefully). It's got a 2.5L V6 in it. Just wondering what my first mod should be to it???? I'm not looking into putting thousands into this car. I already will have a nice stereo system for it. What should i do to the engine first??? not looking for a turbo....im 17 years old and dont have 3g's layin around.
