i have a 2000 gt and was wondering how much pulleys would help, all i have is the k&n air filter. march performance is a few blocks down the street from me and was gonna try to get a guy from there to install it on the side for me. which ones would you get from this paige marchperf.com

 

Personally I would look at the Steeda Pulleys, they make a one piece crank and dampener pulley. There may be some other companies that make it as well. The piggyback design of the stock pulleys and those aftermarket ones just seems like it would be extra weight. The lower wieght the rotating mass is, the more efficient the engine. Now how big of a difference it makes in real world numbers may be insignificant.
