I have a 97 Discovery with the usual gas hog 4.0 liter V-8. It has 135,000 miles on it and I am thinking about converting it to a diesel engine. What makes the best conversion and what is the easiest. (They may not be the same.) Also what kind of fuel economy can one expect??? If it is only 2-3 mpg it's not worth it. If we are talking 30 mpg, then lets get at it!! Thanks.

 

Are you willing to spend $10,000 to do the conversion, you'll need and engine dive shafts, tranny and t/case plus all the little stuff.

 

About 6 mo ago someone on this forum did change to a diesel.

I looked for it but didn't find it.
AsI remember it was about $17K USD.

After you change you can always sell the old motor and other
parts.

But $17K will buy a lot of gas so unless you are going to travel
where gas is hard to get and diesel is easier to get I would pass.

 

£17k to swap an engine? Holy cow! Does that come with free umpalumpas or something?

 

I think that everything has to be imported as we never got
diesels here so the cost is high.

If Land Rover (Ford) will not import the Defender diesel
I may look into finding a 25 year old one in England myself.

A friend has a Camel Disco he keeps in England as the U.S.
will notlet it in, "97diesel" .

I guess they though that with the low top speed and what GM did
to the diesels in the 80's no one would buy them.

Jeep has started putting diesels in but...........we still wait.

The Dollar to Pound is 2.02 to 1.00 so 8415 Pounds gas to diesel.
