Can't on that one Shawn. I have an Code 3 SC pulley. It adds a little grunt but not enough to make it worth the expense and hassle. If you really want a significant improvement go with a crank pulley. However, if you go with the really big one 185 , you might have to make other mods. Namely the idler pulley, and possibly the inter-cooler. The idler pulley is a must as the stock one's fail. The inte-rcooler depends on how hard you are going to push it. Some guys change the injectors too. There are people way more knowledgeable than me on this forum. My wife is from Poland, she has worked out very well.
