Converting Land Rover Discovery to Diesel

We have a 2004 Discovery that we love, but the gas mileage is ridiculous. Our Suburban was a hybrid by comparison. I just got a promotion that came with a company car, and was contemplating selling the Rover. Then I started pondering the idea of converting it to diesel. I'm a weekend mechanic at best, in fact, that's giving me too much credit, but I've been maintaining our cars/trucks and my bikes successfully. Jesse James I am not. This would be by far the biggest project I've tackled.
Does this sound do-able? Is it going to be so expensive that it's just dumb? I have a lead on a very low mile diesel motor from a Toureg that got written off in Michigan, and I was thinking about using that. What do you guys think about time, cost, probability of success?

Only thing that would really put me off that toureg plant is the engine management and probably security system built into it. Old engines dont' have any b.s. I don't know the toureg has this or not, but I would consider it.

Also to go diesel you may need to rethink the transmission, and axle gearing.

Your best bet is to get a turbo diesel out of a defender 110. I don't recall seeing diesels in any other range rover products here in Germnany. Being in Canada, you should have more diesel powered vehicles than we do in America.

There is a conversion kit aval.. Can't recall of the top of my head the name of the company that offers it though. Uses a Brazilian made 2.8l strait six power stroke. Or try to get a TD5 out of the EU.

Edit; here you go

The Cummins 4BT motor is nice for conversions because it's all mechanical* - no electronics to deal with. However, doing a conversion like this requires a LOT of fabrication, scrounging, and money. I recently saw a delivery van for sale with a 4BT, and at around $3000.00, it was about the cheapest I've ever seen a 4BT with a transmission.
*it's also reported to be loud, rattly (well duh, it's a cummins) a bit high on vibration, and some versions don't make much power).
Google 'Diesel Conversions' and see if you can join a forum.
Cheers,

I think a 4BT weighs about 750 lbs., though.

No argument there! All the Cummins egines are HEAVY.

I wouldn't regard what you're proposing as a viable project: you'll have to change gearbox, wiring harness, trans crossmember, exhaust, radiator, fuel tank, fuel filler, springs, and more in addition to the engine. Run, don't walk, away from the idea.

Before you write off your DII, there are some simple things to look at on the fuel economy issue: O2 and Mass Airflow Sensors, mufflers, cats, fuel type.

I'd do a comparison first.

What kind of gas mileage do you get now?

What kind of mileage does a defender get with a diesel? Or, find a similar vehicle that weighs the same with a diesel for a comparison.

I'm guessing on the fly but, I would wager your conversion to probably cost at least $4-5K. Probably more for your local.

Figure out how much you would gain by the extra fuel mileage.

How long would it take to recoup your outlay? Is it worth it?

Diesel here in the US is more expensive than the least expensive gas at the pump.

$4-5K or more, is a lot of gas!

Me, I'd find an affordable used vehicle that got good/great fuel mileage and drive the Discovery less often.

D1 and 2 were available with the international / LR 2/300tdi 4 cylinder and later with the LR TD5 5 cylinder diesel.
But the conversion would be really expensive. Too expensive ...

Years ago - I forget how many - the 300tdi was offered as a common crate motor/replacement for the Buick engine. I think that applied to both D's and Discos.
I'm sure the newer Discos are more complex.
The only redeeming qualities of the new Rovers has gotta be true passion and love of the brand.
If you never look in a mirror, you can justify most anything...

Thanks Mully, you may have saved me from my own foolishness. Maybe a Honda Pilot is a better idea.

Sell it and buy a diesel rig if that's what you want. You'll be $$$$$$$$$$ ahead and have less grey hair. Unless you enjoy the hunt. It would be a job for a VERY ACCOMPLISHED MECHANIC, NOT a shadetree. Good luck!
