I haven't got any first hand experience but...
yes, carbs can be done (there's a post in the gen discussion section (maybe) from three or so months ago. Problem lies in the camshaft position sensor, as you have to get an ignition system to run off that, or just disable the injection system and run the ECU and E-DIS system.
But then, if you're gonna do that you might as well go for the whole lot.
There's almost no extra hard work to convert from carb or EFi to SEFi - there are only 5 wires connectiong most engine looms to the car (a few more if it has PATS I think - ask Mr Stewart); ignition live, permanent (keep alive memory) live, earth, fuel pump, and rev counter.

There is a way to do the ignition, it is so easy, if you can't see it then don't do the conversion, if you still want to do the conversion though e-mail me and secrets never know before or told by "tuning companies" can't be done will be shown!

lol I reckon they're all the same person under different sign in names - multiple personalities anyone??
Using the non-mappable ignition system from a DIS equipped car will restrict the ignition timing and make it hard to adapt the curve for the car.
The majority of tuning companies you're slating make a fair wage out of setting the ignition and fuelling systems up on customised and kit cars using very high quality, very accurate kit.
Just my tuppence worth. I just think they know a bit more about making odd kit run together than I do, that's all.

al my thoughts were as a budget option? i would imagine the ecu from the dis carbed cvh's would be mappable somehow? obviously this would save huge ammounts of wad on equipment cost compared to aftermarket systems. i know ava have grafted a dizzy onto a zetec but iyt looked pooe and there would be costly machining to get the dizzy fitted and the pulleys made to drive it.

The cam phase sensor works much like the CPS as far as I know, so there's no reason why you couldn't use that to trigger a coil pack is there??

OK. Engage brain. You want it to be cheap:
1: Take one rsturbo distributor.
2: Take one zetec rocker cover.
3: Take one variable angle hacksaw.
4: Cut off the rear blanking plate on the rocker cover.
5: Re-fit rocker cover.
6: Drill and tap head with 6mm holes (I think its 6mm)
7: Fit distributor and coil as you would a cvh.

REAR BLANKING PLATE.......
TAP HEAD......
Mate theres nothing like that on the zetec! I think your probably getting cunfuzzled with an injection CVH.
Then theres the cams you'd have to have a cam grund with some kind of drive, and another one amde to balance that....

I think you aren't looking at a zetec rocker cover there. The blanking plates are definitly on there. What do you think I cut? My hand off? Nope, there are definitly blanking plates there, and the cams are already keyed at the same end. If yours aren't then you must be gutted basically.

I don't like your tone of voice excursion. You offer advice all over the site but yet when I put up factual information you think it is rubbish. Now anyone with a zetec engine will go and see the blanking plates and cams keyed at the usual distributor end and realise my method is correct. I mean, the guy asked for a cheap way to do the ignition on his zetec engine. Thankyou for your time but you are the weakest link, goodbye (sorry for that outburst I just had to say it).

Can't see any on mine! oh sorry any of the 3 of mine also what did you do for an oil seal?? i cant't see a way of fitting a dizzy to the zetec 'easily' because of the shape of the rocker can't you gat some pics to help explain how you have done it?

Like Fras said, have you got a picture???

LOL fankyoo chaps
but no m8 seriously the "keys" you refer to are for aligning the camshafts during timing. There are no blanking plates either.

Excursion is 100% correct, there are no blanking plates, and there are no distributer keys in the camshafts..
You wouldn`t be able to map it either so its pretty much pointless if u want power..
