2L Mk3 Fiesta... the term dangerous comes to mind! Good luck with that.

Its possible to do it, you'll need the following:

Engine.. its a good start,
Ecu and wiring harness
Upgraded gearbox possibly 2l focus gearbox
Clutch to go with
Upgraded brakes
Rear axle drum to disc conversion
Possibly throttle body
creating new engine mounts, possibly bulging the bonnet slightly also

1600 zetec s engine should slot right in, but youll still need the ecu, gearbox, clutch and wiring harness

To start with, what's your budget? I mean not all 2 litre engine's are better than all 1.6 engines, but then again the 1.6 might end up more than the 2 litre; example - 2 litre ST engine vs 1.6 Ecoboost.

A 1 litre Ecoboost would be fun seeing I've heard of a 170ish bhp version somewhere.

I think the focus 1.0 eco boost is 162hp in a car weighing less than 900kgs! Id say top speed of 130 min. Acceleration wil be phenemonal too

You might want to concider a 1.7 Puma engine. Its probably a better swap for a KA though of which quite a few conversions have been done.

I don't see much of the point of swapping to the 1.7 I mean its only an extra 100cc's From the 1.6 Obviously. All that money you may aswell go for the chunky 2L and blow the fish out of the water rather than trawl them with a 1.7, okay i've lost track on what i'm talking about

If you can find a clean shell. Why not get an RS1800, still a few kicking about and a future classic for sure. More than likely a lot cheaper than converting. A mk1, I would of thought, would be harder because you'd need to fabricate mounts and stuff. If you fit an engine that Ford has already put in that car, the mounts will be already there plus you can get the wiring harness. As Blaine said fiesta ST 2.0 motor is your easiest option (puma motor would be my personal choice though).
