The Skunk2 Pro Series Camshafts are great. They cost around $750, and made about 35 horsepower and about 20 lbs of torque on my B16 '94 Honda Civic. Takes about two hours to install with the right tools. You do need a timing gun. These cams are highly recommended. You can definitely see a difference throughout mid-range rpm's, but the stock head really has to push itself to get to eight thousand. My next purchase is the Skunk2 cnc ported head, which I read a review on saying it doesnt labor itself to reach redline.
