HKS also makes cams for both the 1.6 and the 1.8.... I suggest that if you have a 1.8L.. you go buy a 99-00 head... you'll get more power then ANY cam swap. You can also modify a 94-97 1.8 head for fit the 99-00 valvetrain/cams. The benefit to the 99-00 is bigger cams, solid lifters, bigger intake/exhaust ports, smoother intake runners and the VICS intake manifold.
