ENGINES THAT WORK:

2001-2002 3.0L DOHC Duratec Engines that work:

-Ford Taurus
-Mercury Sable
-Ford Escape
-Mazda Tribute

2003-2005 3.0L DOHC Duratec Engines that work: (preferred over above years)
*Changes from above years: oil separator/PCV system removed from between heads and integrated into valve covers, larger cooling passages for better cooling, different intake manifold, COP added, cam profile change slightly, etc.
-Ford Taurus
-Mercury Sable
-Ford Escape/ Mercury Mariner
-Mazda Tribute

-Mazda MPV 02-05 3L motors will also work. A few over on CEG have worked through this swap. It appears that the motor has quite a few benifits including, 2001 Cougar timing cover, 2001 alternator bracket, engine mount between heads is installed, SVT oil cooler, and DMD crank pulley. However, the intake on the MPV may not fit under the Cougar's hood. There are clearance issues with the Contour and the Contour has slightly more room. Cost for this motor does seem to be slightly more than the Taurus/Sable motor. Compare costs and weigh the benefits to determine if this motor is worth it for you. A cheaper Taurus/Sable motor might still be a better option if you don't mind doing a little work.

ENGINES TO AVOID:

-Pre 2001 3.0L DOHC Duratec motors: The 3L's previous to 2001 had lots of variations. The water pump was not driven off the cam and the intakes were aluminum split port intakes like the 2.5L intakes. You could install one of these motors but you would need to run an electric water pump. Your 2.5L intakes would bolt directly up to these motors without any modifications (no porting needed as they were split port 3Ls). 2000 was a mixed year so some were split and some were oval port.

-Ford Escape 06-08, Ford Freestyle 05+, and Ford 500 04+ 3L motors run the water pump off of the front exhaust cam creating issues with the Cougar/Contour crossover tube and prevents the use of the 2.5L valve cover on the front head. The heads also have extra valve cover bolt holes in them even though a rear 2.5L cover does fit and bolt down to the rear 3L head it won't seal because of the other bolt hole that the 3L cover/head has. On the 06-08 Escape 3L's the oil cap on the front valve cover sits too high for the Cougar/Contour hoods and would need to be modified if used. The valve covers sit too high for the 2.5L intakes (ported 3L build) but can be cut down and welded back. I'd suggest skipping these motors because it is a big pain (I've done it and it isn't fun). For a full 3L build using a 3L intake it wouldn't be as much of a pain but the other years would still be easier to use.

-Lincoln LS 00-02 did have a 3L motor without VVT. In 2000-2001 the engine was rated at 210hp and 205ftlbs. In 2002 it was bumped up to 220hp and 215ftlbs. The reason for the increase in hp in these motors is due to the direct-acting mechanical bucket (DAMB) tappets vs the roller finger followers (RFF) used in the 200hp 3L motors. Unfortunately being a Lincoln the used motors prices are very high and nobody to my knowledge has tried one but supposedly the heads are different enough where they will not work in the Cougar/Contour. You will pay nearly double the cost for a LS motor vs a Taurus/Sable motor and in the end you only get 10-20hp so I don't think it's worth the time and money for the little gain you get.

-For those looking at the higher hp 3L motors, these engines will NOT work: (Ford Fusion, Jaguar X type, Jaguar S Type, Mazda 6, Lincoln LS 03+ , Ford Escape/Mercury Mariner 09+) These motors use some form of VVT to boost power and this is why they are not compatible with the Cougar/Contour. They could probably work with some custom wiring and ECU from the donor engine but generally this is thought of as a huge waste of time. I'd suggest you steer clear of them.

*Note 1: While Ford did produce the Ford Taurus in 2006 it was only in Canada or as a fleet vehicle in the US so there won't be many of those 3L motors floating around. I suspect they are the same as the 2003-2005 3L's so they would work perfectly fine.

*Note 2: Everything above remains true unless you choose a hybrid 3l motor which uses a 3L block and 2.5L heads. I don't believe the 3L blocks are different enough to prevent you from using your 2.5L heads and installing it into your Cougar/Contour. Some passages need to be plugged on the 3L block, depending on if the block or heads have the extra oil drain backs, when going with a hybrid build.

Any other motor which isn't listed above (3.5L Duratec, 3.7 Duratec, Ecoboost engine, SHO motor, any V8) will NOT fit so don't ask! The entire reason for the 3L swap above is to get more power without having to do a ton of work or spend a ton of money. The motors above would need a lot of custom work. Most are too large to fit in the engine bay.

3.0L and 3.2L SHO Yamaha Engines WILL NOT FIT!
:mad:

More info on types of 3L builds can be found here.

Re:read this first - what engines will fit my car?

Escape/Tribute engine comes with:
Usable oil pan. Minimum YL8E revision but even the prefered 3M4Z if you get a new enough engine.
New YL8Z pickup tube needed for 01+ main studs.
Same or newer Crank Damper.
Newer P/S Pump and lighter pulley.
Usable pre-cats with a better log design. (If not using headers)
et cetera...

BTW the engine itself is the exact same as any other 3L oval port Duratec.

Re: READ THIS FIRST - WHAT ENGINES WILL FIT MY CAR?

I HIGHLY prefer Escape engines. They don't have crazy balancer spacer/pullies and you avoid the 2000MY "Frankenengine"- A bastardized mix of injector sizes, intakes, water pumps, etc. Stay away!

2001-2004 Escape engines, though some recommend against '03 and '04 engines due to possible zircon contamination left over from the casting of the block.

2005+ Duratecs have cast cranks, not forged.

I always use '01 and '02 motors. Lower mileage the better, but you can always have the cylinders honed and install new rings. Clevite rod bearings are a MUST, Clevite main bearings are a really good idea.

ATX- You have a '99, so you need a '99 ATX. It's specific to your build date, which is stamped on your driver's side door. Make sure you have this handy when calling junkyards.

All CD4Es will bolt to the 3L block. Don't worry.

Install a trans cooler regardless of the engine you're hooking it to. These slushboxes are iffy as it is- Make it run cool!

How about a ST220 226hp from 2004. At the moment I have the opportunity to purchase one of these with gearbox, axles and wiring. So haven't been able to find a lot of info on one of these swaps into a 1999 cougar pre facelift. Can it be done or is it one of the difficult swaps?
Excuse me if the Mondeo is equal to one of the earlier mentioned cars but I'm from Denmark, and not too familier with some of the models, sold outside Europe :-/ ..

Also is it possible to make the 3.0 look like the 2.5? The reason why I'm asking is because the rules regarding engine swaps are very strict in Denmark, so I'm trying to better my chances of the car passing mot.

I would think so. Your best bet might be the UK Cougar forum though, as far as I know, no one on this side of the pond has done anything with the ST220 engine.

I told a friend of mine about my recent swap and he said "oh, the engine out of the Freestyle, right?" I was a bit confused and said, "Possibly, I'm not sure if it's the exact same."

It looks like it would work. It has no VVT and looks similar to the Five Hundred. The possible issue I see is that it was mated only to a ZF CVT transmission. Would the bell housing match up at all?

I'm just curious because I hadn't thought about the Freestyle engine at all.

Technically the Freestyle was a station wagon version of the Ford 500 and then the Taurus in 2007 when the name changed. It should work but since it was introduced in 2005 it looks like it has the same issues as the 2006 Escape motor with the water pump being on the front cam. See engine picture below:



Found this article mentioning some differences:

Tech Feature: Servicing Ford's 3.0L Engine

One being direct-acting mechanical bucket tappets to increase power, however the 232hp rating is partially incorrect and the Ford 500/Freestyle did not use this technology (only had 203hp). The LS engine did use this technology but it only had 210hp in 2000-2001 and then bumped up to 220hp in 2002. The 2003+ LS was 232hp but also used variable valve timing which will not work with our setup.

I updated the first post.

AAhhhhh i NOW do know what engine i actually have:)
minde look completely identicall to this on the pic above..same valve covers and SAME fu***ng WATERPUMP (on front cam)
**** hehe.
hey Blackcoog maybe u have a idea what to do with this waterpump. will i have to get the original waterpump?
What do i explain which engine and date i have? (2003 DEZ written on timing cover).
Which HP ranking does it have...hope it's not less than stock 2,5:-D

Hello from ukcougar.com :wave:, I have just started getting the dreaded death rattle from my 2.5 st24 engine, it is just as cheap to swap my engine for a st220 or st200 as it is to repair. The st220 will require modification of the bonet to fit as it sits proud of the engine bay by about an inch, think the Kaminari bonnet has enough space available if you cut out the blanking plate from the scoop but not certain, I am looking at using a st200 engine as i have after market headers and y-pipe and have been unable to find out if they will fit an st220, also purchased a lightened flywheel for my st24 engine and am not sure if that will mount to an st220 either.

Hope that makes sense and is helpful :shrug:

As far as I'm aware except for a tab which might need to be sawn off for your alternator bracket, all 3.0L block mounting points are the same as the 2.5L points, it's just the heads themselves with little extra bits on them that make them harder to use, as such your headers and flywheel should bolt right on. Now, take this advice fully understanding it's from some guy who hasn't done a 3.0L swap himself, nor has any research hours into the european 3.0L blocks.

Hello from the other side of the ocean. Your headers should fit just fine. The flywheel should also work.

Lately the CEG guys have started using 01+ Mazda MPV 3L's.

The reasons are good.

Cougar Engine mount already installed
Dual Mass Damper installed
2001 Alternator bracket installed
NO pilot bushing
SVT Oil cooler installed
Mondeo 3.0L Fuel Rail installed
Metal oval port UIM & LIM
Contour/Cougar/Escape timing cover.
Baffled Escape oil pan

Of course they're a bit more expensive than a Taurus engine, but they're still cheaper than an Escape engine, although you can't find any with really low miles like you can a Taurus.

so if I havent gone to 3 liter yet, would this be the route to go??

It would certainly be the simplest way to go, pull the alternator and bracket, cut the tab, put on your alternator bracket and alternator, then either port the heads with bugzuki plates or make the adaptations required to use the UIM. The EGR is actual not that far from the stock position, be this a good thing or bad I don't know, you won't have much room to work up a adapter, but then you won't have to move it very far either.

http://i1118.photobucket.com/albums/k605/Pblack003/PreMazdaMPV3L002.jpg

And it looks like the EGR valve is directly electronically controlled, so you would have to use the stock EGR system from the Cougar and somehow adapt the vacuum lines needed to run to the EGR vacuum solenoid. Or just do an EGR delete for half the cost of adapting the EGR.
