Diesel Conversion ??

[Invictus]

Would it be feasible to convert a 1999 Expedition to a Diesel Engine ?? Finding a donor would be no problem..

I doubt it but then again...deep pockets can do just about anything automotive.

What engine were you thinking of swapping in?

 

[Invictus]

I was thinking about a Cummins Turbo Diesel..

Too heavy and a tad bit too long, I would assume.

A new front end would be in order. Not the body but the subframe and suspension.

Would a compatible tranny even fit in the hump?

I would say it would be easier to convert a Dodge QC into an SUV. Especially since in Mexico they have a Ramcharger that is based off the Ram reg cab, short bed.

Hell, even stretching one of those would be easier! If you could get it...

i have been toying with this idea for a few months now and i called an engine supply company to get an idea of weights. the 4.6 weighs 400lbs, the powerstroke 7.3 weighs in at 870! for transmissions options though i would prefer a stick and then swap in a dana 60/70 rear out of a superduty to get the speed sensor. i would think that a heavier front spring will definately be required for stock applications however since we are installing suspension systems in our Trophy Truck conversions the new longer/heavier coil would most likely work.

has anyone else given this serious thought?

what about the 6 liter? with some good head studs they can make alot of power bone stock and hold up. i think it is a bit smaller and lighter.

anyone know the size/weight difference? what trans goes behind it? what year was it offered?

2005 diesel trucks for sure

I'm probably wrong about this but I'll give it a shot. My buddy was looking to get a 1997 f250 diesel. I never saw it, just read the add.

Correct me if I'm wrong but wouldn't that front end/clip be the same as a 1997 f150? wich is the front end of an EXP?

I'm not sure but that would end up being a 7.3 and thats a big old engine which I don't doubt is quite heavy.

yup, 870LBS. the 5.4 only weighs 60 lbs more than the 4.6 so there are two different rate springs for the front but if you were going to install an engine (and trans) weighing roughly double the OEM weight tht only way to do it is to build some shock hoops and add a set of coilovers with dual rate springs to keep the porky bastid from porpoising down the freeway.

once my shop is finished i'll be looking into this. in the meantime anyone with good info, constructive criticism or a good **** story feel free to chime in.
