I have finally managed to get a V6 Mondeo to act as donor to fit the engine into a Mk1 Fiesta, it should fit as I have previously measured.

Engine mounts shouldn't be a problem, nor the exhaust or wiring,

I will need to remove the power steering pump though and maybe move the alternator to the front to clear the driveshaft

Has anyone else ever attempted this? or know anyone that has put the engine in another car in FWD format?

Cheers,

Paul

you running it as a front engines, front drive setup? or swinging the thing around to drive the rear wheels?
or being really mad and sticking the unit in the back?

anyways good luck. oh yeah, is it the 2.5 or the 3.0ltr?

thanks Chris.

Putting it in the front, couldn't cut up the car I've had it for 13 years and it was my mum's from new!

It's a 2.5, got hold of a whole car as a donor! I'll junk the Cats and put proper tubular manifolds on and an induction kit of some description. I think 170+bhp in a car weighing about 700KG's should be enough (I make that 240bhp/tonne in standard tune, 285bhp/tonne @200 bhp), plus it will be very reliable.

I've got an RS Turbo box with LSD if it will mate up or will see if the diff will go in the MTX75??

May have a problem with the radiator being a tight squeeze.

cool. a solution for the rad is to stick it in the back. i read a acticle on a Mini with a rover V8 up front and the guy just mounted the rad in the boot. may mean cutting a bit though!

post when done

I'm interrested how it will steer - lotta weight on the front wheels. You'll change the wheels / suspension set-up won't you!!!

The aluminium V6 mondeo engine won't be much heavier than the cast iron, kent engine, I already have fully adjustable suspension on the car and will be bracing the front end for extra stiffness. I'll be weighing the engines to compare the difference as well as stripping off parts that aren't required such as power steering, the battery will go in the boot as will the extra large washer bottle I have. Back seats will probably go back in to balance things out a little.

Back seats go back in??? Better keep the extra weight low . . .

And why not add a bigger fueltank. Have fun with the Fiesta and keep us informed with pics 'n specs.

I have learnt from my Chimaera that extra weight on the rear end sometimes helps the handling, I have just removed about 50 Kg of stereo from it and it is really different now.

I have already fitted the bigger tank from the Mk 11 XR2 but will try to fit the Mondeo one in if poss. I'll try and get some pics up of how it is now and of progress.

Paul, xcse my french but what I mean is: keep the weight in a low position: closer to the tarmac.

Oh I see what you mean, point taken. Although the car is less than 3" from the ground at the front!!


Engine bay as it is at the moment with Kent engine....

Well I have now stripped the V6 engine down ready to try in the engine bay, I have had to remove the alternator from the rear mounting position as it will foul the steering rack, but everything else seems OK. Have compared the driveshafts and will need to make hybrids with the inner half of the mondeo and outer half of the fiesta shafts. I've removed the power steering pump as well. The alternator will have to be mounted where the air conditioning compressor would normally go and the belt tensioner repositioned to suit.

I'll take some photo's when I get the engine in place.

How would you do this? angle grinder plus welder or is there a more realistic solution - wont they be severely weakened, and what about them being balanced or do you think it will be such a small difference that it wont be noticed?

Ive (well ok, my dad) extended and shortened solid propshafts by making a sleeve to join them, tig welded and finally drilled and pinned for a little extra strength.

Its held 300BHP/350ftlb but I'm wary of putting much more through it without fitting a safey hoop.

Neat job, did your dad do it in a lathe? what car is it in?

As Eliot has done, I will probably set it up on centres on a lathe, that way I should get accuracies greater than 0.01mm. Then weld the two shafts together where they butt up and turn down the weld and then weld a sleeve over the top, giving 3 points to the join. As long as I don't get too much heat into the shaft it shouldn't warp during welding. Balancing shouldn't be a problem as the diameters of the shaft are quite small.

It a front prop on a range rover based kit car with a 350 chevy in it (See my profile for web site), So in theory its taking half of the current available power because its permanent 4 wheel drive.

It was all done on a lathe to ensure accuracy. It has several layers of Tig welding also.
Dont bodge such an item, if it breaks - immagine that shaft flailing around under your engine and feet!

I also have a coupler shaft that connects the autobox to the transfer box that's welded together - we expect that to break first once the turbos are fitted as we will be looking over 500ft/lb torque.

I would be interested to know how such propshafts are "professionally" extended/shortened/Joined

Can anybody advise on whether the LSD from a series 2 Escort RS Turbo will bolt straight into a mondeo V6 MTX75 gearbox?

very good question eliot. i would be interested to find out to.

asked my dad a while ago and he said that they used to cut the shaft to the required length and then spin them and "forge" them together like they do drill bits! dont know how strong that would be, and cant see it being stronger than the one you have done.

thanks Chris.
