You been reading the same issue of Fast Ford as i have then.

The one with the Orange Fiesta on the cover?

It looks simple enough to do, the only thing that concerns me is the fuel tank and pump. I have 2 1800 zetec engines and looms at home and i am considering putting these into my 1.1 Mk3 track car project and my Mk3 Cabby.
Again, like you, just need to speak to someone who has done this conversion before.
