Ford mondeo st24 2.5 v6 engine
Discussion
Anything will fit anything if you try hard enough 
. Its a fairly wide motor mind. There is an engine mount up high on the pulley side (front) of the lump so that could cause a problem. And as far as the gearbox is concerned it may be easier to fit it to an MT75 gearbox as the Mondeo's MTX75 is a FWD version of that.

There are 2 versions, one which was in all the V6 mondeos including ST24, that being 165bhp with 220nm torque. And also an uprated version which was fitted to the ST200, this being 200bhp with a slight increase in torque.
Both units are all alloy, chain driven cams, 2.5l with variable inlet tracts.

The Dutch Westfield importer has developed a Westie version with the Duractec V6. Reputedly, it's lighter than most 4 cil. car engine options (well, it should darn well be lighter than that Pinto boat anchor, for starters) and it's a bolt on to the MT75 Sierra 'box.
After a short discussion with the Dutch Westie folks, my plan is to use a SDV (Single Donor Vehicle) starter kit, a £100 Sierra and a 2.5V6 Duratec from the breakers' yard for some good old fashioned low(ish) budget fun. That, or I'll be refurbishing a cheap Chimaera when the time comes...

The lump from the Granada Cosworth is also worth a look.
It'll use the same mounts as the old 2.8 and 2.9 V6 cologne engine, will mate up perfectly into the MT75 gearbox, and has stock 195bhp and 190 odd lbft.
2.9 V6 24v.
Lots of people are getting 200bhp from these with no cats on and new engine mapping.
People are putting them in the 2.9 XR4x4 Sierra anyway, and it's just a few small mods to make them fit. Good strong engine.
I find the 2.5 Duratec a bit lazy low-down, wheras the 2.9 is much more agressive in it's torque delivery from idle!

Yes, but isn't that a fairly heavy iron block lump, and therefore maybe not that well suited to a Sevenesque lightweight thingy?
That, and early 2.5 Duratec V6 engines seem to be going for peanuts (especially for such a modern engine) as the Mondeos they're in are around in comparatively big numbers, and lots of them end up getting knocked...
I'm sure the low-down laziness won't be much of a problem when it's only got 500 kgs worth of car to punt around (I was thinking aeroscreen, no heater, carbon wings and seats...)!

Yeah, the block is iron I believe, but the heads are ally.
Overall size is quite big, as big as the 2.5 Duratec. Not as compact as the old 2.9 12v Cologne, but that had heavy iron heads.
Not sure on actual engine weight, sorry.
Your right about grunt and 500kg though. Tis just very nice to have almost all the torque your gonna get from idle! Waiting for the lunge in the 2.5 Duratec is weird when your used to instant push. Still, thats in my girlfriends v6 Cougar. I'm sure with only 500kg to push around it'll be adequate and probably more controllable!
Also, like you say, tons about now...

Theres actualy a third version of the 2.5 litre Duratec that you've all forgotten.
That which was fitted in the original Noble M12 GTO. We can get 360bhp from this with fairly minor modifications. Its very strong, has another 750rpm on the rev limit compared to the standard version and of course a pair of T25's.
I just happen to know where theres a good one which we could supply complete with turbo's, management and ancils, upgraded to 360bhp, checked and run up on a dyno with power plot etc. for around £5k. Now that would go well in a Tiger!!!
Best Regards

Actually then, there are four versions 
My girlfriends Cougar(2) v6 has another 5cc I believe over the same engine in the Cougar(1) v6.
Some kinda weird mid-life facelift that was not seen on all Cougars. Seemed to be not many made, and only from 2000-2001 ish, and they still produced the old shape one with the other engine.
Weird but true.
Wonder what other engine changes they made, seems weird to alter pistons or crank for no reason whatsoever!

I briefly thought about that one, too. Would probably have a turbo sticking out on either side of the bonnet of a Westie - at least the exhaust routing would be fairly simple!
't Would be even madder than the souped up SEights Westfield did in the '90s - and those were pretty, er, hardcore... I wouldn't even try to drive it in the wet.
That, and somehow I doubt that like Mondeo V6 lumps, M12 engines will be available on Ebay for £50-100 anytime soon...

The Mk.2 Mondeo uses a slightly modified version to get 170 rather than 168bhp. The Ford 2.5 V6 inlet manifold isn't "variable" as such. For each cylinder, 1 inlet valve is fed from the throttle via a relatively long inlet, and the 2nd valve is fed down a short inlet. Under 3500 rpm a butterfly valve closes the short path inlet, making it act like an "8 valve" (ok, 12 valve) engine with good low rev torque. I dunno about this supposed lack of torque at the low end, it seems to pull like a train virtually from tickover.
Anyway, to get to the point, the old engine uses vacuum hoses to open/close the secondary throttles, the newer engine uses electrical activation. Either way the valves can stick due to a general build up of dirt. The ST200 versions use a different exhaust, different cams, different flywheel, different engine management setup, polished inlets (technically "extrusion honed" and a fatter throttle/butterfly. The inlets and throttle are commonly used to uprate standard 170bhp units.
If you are transplanting it, it's worthwhile replacing the water pump. The original impeller is plastic and can fatigue, leading to overheating and block-warping. Equally, make sure it hasn't been scrapped for that reason!
Thinking about it though, wouldn't an X-Type (4wd, V6) make a great donor car? Pretty rare at the moment but bound to become more common. *Slurp*

Only difference between the 168 vs 170 is the 5cc and the actuation of the variable inlet tracts then.
Makes sense.
The ST200 2.5 v6 engine with 200bhp is the one with all the mods Apache!
The old Peugeot 306 S16 engine uses pressure actuated butterflys for high end breathing, yet Peugeot dumped that technique as it was unreliable as it got older.
Thats probably why the later 170bhp models used electronic actuation.
I found that for a v6, the Cougar one wasn't that great until 3000rpm. My XR4x4 pulled like a train from idle, almost violent. The 2.5 Duratec is quite smooth and doesn't begin to really grab hold till 3000rpm.

why not push the boat out a bit and stick a LS1 in there? you should beable to find on in the UK for around 4.5K (see boosted LS1 on here) or similar (in $) from the states. these things are smaller than a rover V8 and give around 350bhp standard (from a vette). bolt a top mounted supercharger on there and 500bhp is easy. also there is a huge range of tuning goodies for these units (inc. a rear munted turbo kit! hurmmmm that could be interesting in a westy!!!!). you would pay a little weight penalty, but then you would also get 5.7 ltr!!!!
thanks Chris.
PS. whatever you choice is, keep us updated. always nie to see peole looking at things a little difrently.

That'll be a French build quality issue rather than an inherent flaw with the concept. Other manufacturuers have used it with no reliability problems, Honda on their B18C4 VTEC lump for one, and Toyota on the 3SGE/3SGTE for another.
