Hi Davel - I spoke to Mogsport and all they seemed to be offering (after an air filter swap which I did myself) for the black top 1.8 zetec was a full-on 4x throttle body conversion with piggybacked ECU, at an eyewatering cost. Or a turbo, even more £££. At these prices, it would be better to just change the car, both in terms of value for money and because a heavily reworked 4/4 could well be less saleable.
I went for the Librands full exhaust (4-2-1 and sport cat) and this has improved driveability considerably, without affecting the essential character of the car, or (I hope) it's saleability (Librands exhausts are seen as a desirable option), and has not affected the insurance premium.
I think if I really want more power (and I'm not actually sure about that any more), I would be better buying a +4 or a roadster. Maybe in a couple of years.

PS just looked back at earlier posts. Don't change the throttle body - it's the same on both the 1.8 and 2.0 black top zetec!
