You engine bay looks identical to our U.S. version of the Zetec(except the U.S. one is a 2.0) Only difference that I spot is your throttle cable is going the wrong way lol, I know yours is RHD & mine is LHD. You've kept that bay looking real clean, props!
I would get different wheels ASAP, lots of OEM wheels look so much better than those. Then a drop, header/exhaust, tune, intake, black out the headlight housings, tint, color-match all the trim, debadge, etc. Start modding!
Can't wait to see what you do
People have done V8 swaps in Foci, have you checked out this forum?
