Or you could install the Magnuson nose like the one below and switch of pullies when you want to creat more boost (ie you put higher octane fuel and you could change out your pulley in about 5 minutes) I have the nose and 2 other pullies for sale if interested. It comes with the 3.4" pulley (good upgrade) 3.25" pulley (recommend higher octane fuel or cai, pcm reprogram, exhuast) and a 3.0" pulley (recommend cam and/or heads) PM me if interested!
