2.0L into a Fiesta zetec S?

Is this an easy conversion?

Will the lump drop straight in on the original mounts,
which box should I use
Will the loom need splicing and dicing
Will fuel pump and injectors need replacing
would the standard brakes (upgraded discs and pads) cope

Looking to buy one now that the S1 and the daily runner are up for sale, but worry I will soon tire of the Fiesta's performance.

Also, would Mk3 Fiesta Recaro sets bolt in or would the bases have to be changed

Cheers

Matt
