There is only so much you can do without forced induction. The mods you are looking for are not going to give you substantial power increase. One thing to remember is that every time you modify the engine for more power you are sacrificing MPG and longevity. You cannot have both when boosting power:( Headers are great...if you are creating more exhaust. More exhaust means you are creating more power. Get the point? Economy and power do not go hand in hand <img src="/forums/images/graemlins/shame.gif" alt="" />
