It depends on the engine size You know 3.8L, 5.0L it really matters......Are you going with the same size or not ? (REPOST WITH THE DETAILS)
It's a 2.5L, and want something BIGGER ...?
the only sizes that fit are the 2.0 zetec, 2.5 duratec, 3.0 duratec on the sable, taurus, and some escapes depends on the years.. go to newcougar.org for information they have a how to for that and the engines that fit.
you should be able to.the only thing that might be different is the wiring harness
Bascially they are the same engine.
It should with minimal problems fit. There were some slight changes to the Duratec engine in the cougar between the '00 and '01 model years, including a better, and easier to replace alternator. but a straight swap shouldn't be too hard. Another thing you can do is a swap from a Ford Contour or Mercury Mystique. or if you want some more power and are willing to go through some trouble to get it working right, the 3.0 liter duratec out of the sable, taurus, and escape vehicles of similar years provides a nearly drop in fit with substantially increased power.

nono
If you are swapping the Vulcan OHV engine, it will work without issue. If you are attempting to swap the Duratec DOHC engine, it will bolt in, but the computer will not be capable of running the engine.
The answer is no. Not same engine either. 91 couger has a 5.0 (if its a v8) and a 3.8 (if its v6). a mark viii will only bolt up to a 4R70W transmission. A 91 couger does not come with a 4.6 ( The 4.6 Was not released until 1994)
The Ford Contour and Mercury Mystique here in the USA used the same spec motors, and in europe, the Mondeo used the same motors from the early '90s till around 2002. You can also mount a 3.0L duratec from a Taurus, Sable, or Escape, though the swap process is a little daunting for most people.
automatic or manual doesnt matter because that's talking about the tranny. ONLY swap a camshaft if its the EXACTsame engine.
yes you can swap a 2.5 in to 2.7 but u will loose some power from
I can't find the documentation, but the basic law is that the engine you swap in must be from a vehicle that is the same year or newer as the vehicle that you are installing the engine. So if you car is a 2000, you can swap in any engine from any car that is a 2000+ model, but any engine from 1999 or earlier is off limits. It's a good idea to have legit paperwork to prove the origin of the engine as well.
There Several Swaps that can be done to the ZX3 Focus . Kugel Komponets offers a V-8 Swap to put a 5.0 or a 351 Windsor. To do so it must be converted to Rear Wheel Drive. I have also Seen a 2.3 Turbo Swap from a mustang.also Rear Wheel Drive Some Swaps to do and Keep it Front Wheel Drive would be: A SVT engine swap which can be done with little modification,A V-6 Cougar Swap, A Duratec Swap, a Sho Taurus Swap. Others can be done if u wanna pioneer a design.
