Well first problem is you've used the 1.6 Zetec which in silvertop form is utterly shite and not even half as good as the CVH you are replacing. You can get it running but to be brutal don't bother, get a 2 litre silvertop from a Mondeo and a DEEP, DESK or DEWY ECU to run it all. Ironically this will almost certainly be cheaper to insure.
