ill help you install it since you live in vb, descently close to my house, and id stick with the stock b16 cams if your trying to spend as little as possible and spend the money on descent turbo parts.......your gonna need a new clutch also , your stock shit will fry in a hearbeat......and im not really sure if the gsr cams are gonna be better, since first off the b16 head flows better than a gsr head so you would think that the b16 cams would be matched to the head in terms of power making capability.......
