true...however the point of topic is that he wants VCT...what saleen says is tru about the worked head but the ability to have the cam adjustment on your car ZX3 is a good thought but in reality its a handfull...if you got the cash you can do anything.
if you care to know...you would need to aquire the SVT head, the SVT exhaust header, the SVT ECU and wiring harness, a Ford Racing Intake Manifold and i believe it uses a 4.6l throttle body (ask CRTZX3) you would need to remove the corresponding zetec parts and replace (that includes running the entire wiring harness...which may or may not work with everything verify with others)keep in mind there is an issue with the location of the SVT header and some wires that may cause an issue.
