Jeez! When you "talk to" (or are looking at the website) of whatever company is selling these adjustable cam sprockets, is it understood that you require sprockets for (I presume).......a 2003 Ford Focus, built for the American market, that has the PZEV 2.3 litre Duratec engine? It has chain driven camshafts only. To be honest I'm not sure if exhaust adjustable sprockets are used/available or if it's just the intake sprocket.
i posted up the website, well i thought i did. damn must have not went threw. i book marked the website and now it wont let me back in and i cant find it, but i guess it was some bull website since no one has ever heard of this. ill research the CFM ones you guys were talking about... thanx
