what is the difference between the 98-00 zetec and the 95-97 zetec?
and whats the difference between a fouse zetec and a contour zetec?

98-00 Zetec are equipped with VCT (Variable Cam Timing)

95-97 Zetecs are not, They have EGR (Exhaust Gas Recirculation).

Focus zetecs are basically the same, Just more horsepower stock.

99-00's also had returnless fuel.

is there a way to change over a 96 to a VCT? i

...why?

just wondering. if there is plz tell me.

It's probably possible.

But why? When the VCT Solenoid goes that a 600 dollar fix. If you think it will make you faster, No. It will give you a whopping 5 more HP, and practically no torque.

Basically... EGR > VCT

but if its vct, then i could probly use svt focus cams. that is what i was thinking

different head.

Plus, If you want a set of cams here:
