i heard the rev hard kit is better for bigger engines or a built d-series, because of the bigger turbo, but for the price yes i would go with it.My suggestion is go to ebay they usually will have 1 or 2 greddy kits there a month that are used and come with a fmic and bov for right around a grand or less.save some money and buy it used. just make sure all the parts look good and the person you are buying from is reputable
