NOt sure if anythings been changed but they were factory euro 16v cams witha ported and polished 1.8l head. There was also some chamber work done to unshroud the exhaust valves which is good for 15hp on a NA motor. The motor was fully balanced and blueprinted by Ellsworth machine in Mountain View,ca. They are the machinist for Bruce Canepa. It was done right.
