You would be best off going down to a 2.5" pulley. I believe you have a 2.8" stock. You will need a good flowing intake, at least a 180* t-stat, and some colder spark plugs to support the extra boost.

Ya I was looking at that when I got the car it looks very restrictive I tryed to remove the MAF screen in the throttle body but had to put it back in because of very poor idle I was think if I got a better flowing intake that it would help with idle when driving at low speeds because that is when i noticed the poor idle when driving at low speeds
