Modern Mk1 Escort
Discussion
Hi
I'm new on here so bear with me, I've been busy over the last 3 years creating this, I started out to make a classic car a reasonable modern car with a little bit difference, the original condition of the Escort was well gone so I decided to graft on a floor pan from a Sierra, the power plant had to be powerful however power doesn't come cheap unless it's a V6 Duratec from a Mondeo so that's what happened, mated to a MT75 gearbox, I ran the car for a year to shows and stuff, goes very well, however the gearing is very high as is all Sierra Cosworth but a wheel and tyre size up so it has a theoretical top speed of 167mph, however I like the way the car just cruises along at 70mph effortlessly on motorways on little fuel, but the price to pay for that is the lack of acieration, now the easy option would be to drop the gearing a size or two, but I don't do easy so decided over the winter months to Supercharge the V6, now I have the best of both worlds, this is a really comfy fun car to drive as I fitted the leather interior from the Mondeo and it sounds the nuts

The car has a wheel track of 6ft & a wheel base of 8ft which keeps it very stable, also with the Sierra Cosworth rear drive and axle set up all helps, the arches are all steel hand made (took me flipin ages to make and get right)this is truly a dream to drive you just can't stop driving it, there is no other like it as a road car.
This is not a Cosworth engine, It's a 2.5 V6 from a Mondeo and they are a very misunderstood in the petrol head world hence there is almost nothing available other some add on induction kits available, it's also what makes this power plant undesirable and cheap as chips, that was the single reason I went for this engine, I knew I could make it fly for next to nothing.

Presumably, being a modern engine, it's not to heavy for what it is and not too nose heavy?
You seem to be a very talented man, well done.
That was the plan, but it was more luck than anything for balance as there was only one position where the engine could go, it ended up a bit further forward than I hoped, it was a gamble but worked out really well in the endYou seem to be a very talented man, well done.
It is a M45 from a Merc SLK230 and I also thought it might be on the small side, however that said once you do the calculations it works out just fine, there are other parameters as well e.g. the charger is geared 2.3:1 that means for every revolution the charger develops around 1400cc of air, then there is the very short feed pipe to the plenum chamber, no intercooler, instead I have water/methanol rigged up to keep the charge temp down, also what I think makes this work is this engine type is renowned for being lazy in the lower rpm the reason for this I think is low air flow below 3500rpm so the engine is crying out for some sort of forced induction help below this rpm, by using a by-pass valve set up from a Mini by just flipping the throttle it closes the valve and glides into boost which makes it very drivable.
I've looked at all that but it's always a question of money, the 30L lump still a bit pricey but getting cheaper all the time, the other combinations of heads, upper & lower manifolds also cams, at the end of the day your only trying to improve the induction side but your really just flogging a dead horse, all the above combinations are splitting hairs, force induction is the only way to release the potential this engine has.
When researching this engine, I found that Ford did build 3 Mondeo's with the Vortex supercharger fitted to the 2.5 with some stunning results, however this was binned due to the company car tax laws where the majority of that size of car is sold and that's when they favoured the 30L lump, as said before there is only one way to go with this lump whatever combo you have.

I'v got at the moment is some crappy footage taken last summer without supercharger

Are you taking this to any ford shows this year?
Looks great by the way...
Not many I can go to due to work commitment's during the summer months, will be at some local shows to me.Looks great by the way...
It took me by surprise at the last show I done because it won best in show at the Selkirk vintage car rally

It was always going to be a bit of unknown how the car was going to handle, but could it be that wrong using tried and tested Cosworth set up front and rear lowered, the only fly in the ointment was the car is lighter than a Sierra also 9" shorter so it was an exciting first test drive, but I need not worry the car handles well.
Cheers mate, I have a tracker fitted. The process involved in making the adaptor plate was very simple the secret is accuracy, the following pics hopefully show how it's done.
First I made a plywood template to get the rough shape of the MT box, then from a chunk of 6mm plate milled out the centre hole to fit over the crankshaft exactly, then to get the exact centre of the dowels you can see I made up a couple of dummy dowels with threaded in centre punches to mark the hole in the correct place, at this point it would have been easy just to offer up the box into the spigot bearing and mark off the retaining bolt holes to the plate, however there is to much play on the input shaft to make that happen, what I done was make up a disc to fit the hole for the crank, then make up a piece of tube that fitted over the bearing carrier snout on the box snuggly, weld that onto the disc, then tack weld the disc into the hole using all the engineering practices to keep all straight and square, now slip the plate onto the box and mark off the bolt holes, only then can you cut all the centre out, The starter on Duratec V6 can only fit in the one place because of it's shape into the block, I made up a mounting plate to weld on to the adaptor plate, to make things a bit stronger to compensate the loss of some top end retaining bolts because of the starter motor mounting, I welded on a block of alloy and threaded to fit the adaptor plate, (almost done) two other mods were made, first it was found the bearing carrier snout was a bit short, however I found much longer one from a Transit MT box which was machined to the correct length, the other mod involved the ball pivot for the clutch release lever which I made longer which I made adjustable just in case it needed to be on final build, It's worth mentioning that if you are using the V6 flywheel it just skiffs the inside of the bell housing, this is cured by a just taking a small amount from the inside of the bell housing with a flap disc.![](http://thumbsnap.com/sc/Eu8rWvCu.jpg[/img]</a> <a href="http://thumbsnap.com/N62pybdq" Target="_blank">[img]http://thumbsnap.com/sc/N62pybdq.jpg)

Cool car! A V6 in a small 2 door old car... me likey... :-) I like the fact you have kept the interior comfortable- stripped out interiors wear thin after a few months!
How heavy are these ford V6s? They are very strong motors I know that. Good choice.
First never liked a car without interior, you say small car who would have thought that the Mondeo interior would fit inside a Mk1 Escort? secondly I weighed the engine fully dressed and weighed 63kg, there was a guy interested in fitting one into his hovercraft but decided it was just a few kilos over his limit.

Very lovely thing. Is there a hole there at the top of the gearbox below the starter though?
Id be way too paranoid about things falling into or flying out of there.
You needn't worry my friend nothing is going to fly out or get in for that matter, when the engine gearbox is installed you can't see anything Id be way too paranoid about things falling into or flying out of there.
Correct, remember there are no cats, no power steering pump, no air con pump, no secondary valve system and electronics to control it, no EGR equipment, and so on, when you see this engine stripped down you would be surprised at how small it is after all the planet saving stuff is removed.
