The zx2 vct is basically a replacement for the EGR valve they didn't put in our cars.
Hah interesting. I've never heard of VCT being used for emissions control. That sucks. And FYI the SVT system is a little complicated too since it has the dual runner intake and the VCT gear... most people who run high numbers or boost end up deleting it all anyway. lol
I have no intentions to swap, really... until my Zetec blows up. If I have the time and money I might try to get my hands on a Duratec and MTX-75. Otherwise I'll just track down another old beat up Zetec, since they are pretty much everywhere.
ssc I have no idea what you're talking about. english?
