http://cgi.ebay.co.uk/ws/eBayISAPI.d...MEWA%3AIT&rd=1
just won those on fleabay and just wonderd if anyone had set any vernier pulleys up on a ZT before so i can set them up first time (ish)
i think i read some where zetec turbo's like the exhaust cam advancing a bit but not shure about the inlet cam (im probably talking bollocks here)
im running 130ps blacktop cams and omex so the map can be tweaked but i dont think changing the pulleys is going to efect the map that much i hope

The same way you set any vernier up. 
Get true TDC, Stick the belt on, then rotate the engine crank the number of degrees the cam manufacturer state. Using a gauge. Then adjust the vernier so you have maximum lift on the cam using a DTI.
"Generally" cars feel better with the inlet cam slightly advanced than retarted, they feel "perkier" But don't go doing it by eye. Get a the gauges out.

Set it all up accurately, and you'll get the maximum benefit from the cams. I have no idea how good those cams are though. TBH I'd not go for any unknown makes, only Piper/Kent or similar.
But like I say, go for what the manufacturers state, and it'll be as good as you can get it.
As for retarding the exhaust cam for emiisions. I couldnt say either way.

Are you talking about the possible use of other specification standard equipment cams in a turbo zetec?
I am currently mapping all the profiles and timings of the standard zetec cams available to come up with a decent solution for turbo cams. I may have newman grind or re-grind some to my spec.
I will let you know how i get on and what i find.
