I have looked around but have been unable to answer these questions... I would much prefer to have a diesel P38, but is it possible to import them to the US? If not due to regulations, does anyone know if it is possible to replace the gas motor in an existing P38 with a diesel one? I know the latter would not be an easy task... as far as ECU's, etc. Thanks for any insight!

I can't claim to be an expert on US import law, but I doubt a diesel import would be possible. You also have to bear in mind that regulations vary from state to state (you might wish to put a location on your signature or in your profile).

In terms of converting, simply find an (very) good independent LR specialist, tell them you want a diesel p38 and write a blank cheque. You might get one in a year or two.

The factory diesel p38 had a 2.5litre BMW m51 engine, it produced 132bhp and 197 lb ft of torque. I don't know how common these engines are in the states (or what the parts situation is like) but on the plus side all the parts are available off the shelf (in the UK) to convert a petrol p38 to diesel. Driven carefully you can expect to nudge 30mpg. But as your gallons are the wrong size thats about 25mpg (less if you gun it) for you.

At least one, if not 3, p38s have been fitted with the 3litre BMW diesel engine (170bhp in a mark 3 Range Rover). Faster, more economical (maybe) but with the same disadvantages as the 2.5 engine.

There was a company who fitted Mitsubishi 2.5litre diesels into p38s here in the Uk. There were issues though, I believe the front axle hit the sump under articulation.

So, lets assume you can find a decent diesel engine (right size, weight, rpm range etc) in the US that has good spares back up all you need to do is make up some engine mounts and an exhaust system, install a new fuel tank, pump and lines, rewire the engine bay so that the new engines ancillaries can operate, connect the engine to the vacuum system, make up a gearbox adapter, install the engine ECU, reprogram the gearbox ECU, reprogram the Becm, alter the ignition wiring, install a bigger battery and some extra soundproofing. And breathe.

On the plus side, the EAS system will be unaffected.

Now assuming that was all available, I reckon it would cost you, say, $8-12,000.

Now if you look at your existing driving and fuel bills, calculate the saving gained by running on diesel (isn't it more expensive over there?) and work out how many years of that saving it would take to pay back the cost of the conversion. Only after that point will you start to save money.

Now would $8-12,000 buy a lot of petrol? Maybe some jerrycans and a roof rack if you plan to venture farther afield?
Or a rebuild for your v8 which could result in improvement in economy?

In FL we can put pretty much anything in there. It's "supposed" to be of the same year or later as the car, but we don't have any sort of checks, so I doubt anyone would know in a million years.

Polster.

The BMW 2.5ltr turbo diesel was fitted to many makes/models of vehicles in Europe and the colonies, though unfortunately not down-under and would be a better platform to mate to your P38 compared to the 3.0ltr donks ! (reliability and U.S. parts issues)
Forward Specialists in New Zealand offer the aftermarket 2.8Ltr 4 cylinder Brazilian made TD engine which is the forerunner to the earlier Disco' 2.5ltr turbo diesel engine, otherwise visit the www.marks4wd.com website that offer Rangie P38 bolt up kits ?

Re: Diesel rover in US / gas/diesel conversion?

I dont get it, you guys have gasoline at a national average of $2.64 /US gal (so says the AAA) We have diesel at $6.97 /US gal over here, Given half a chance and a bigger wallet I would run a tuned V8 and LPG it too.

Stick with the delightful V8 noise and acceleration as the diesel option is probably going to be too much P38 hassle in the long term. :(
