Zetec-E 1.6 is ALWAYS waste of money. Zetec-S 1.6 is better for N/A use.

MK4 Facelift? This one? http://en.wikipedia.org/wiki/File:Fo...t_20090227.jpg

Severnvalley put a 2.0 16V turbo in such a car ten years ago. 300+ bhp. As mentioned before: custom engine mounts and "small" modifications.

For this car a blacktop Zetec might be the better choice because of engine mount position. Just be sure to use a IB5 gearbox with the Zetec. The MTX box fitted to Mondeos, Focus' etc. with this engine won't really fit into your engine bay.
