how much you want to spend?
either get the factory blower, put a turbo on it, or if you want a bit of power tune it.
check the performance section of www.customtacos.com for performance mods for your 2.7... people are runnign anywhere from 100-750hp on them! <img src="/forums/images/graemlins/zombie.gif" alt="" />
