double cabs

as stated befor i have a nissan pathfinder i have just returned from my dealer ..
the catalist has been changed by nissan so reducing the mpg
the resisters ect on each fuel injector have a differant value if these are not entered seperatly into the computer it makes a considerable differance to the mpg

still getting just about 40MPG out of my landrover at 56-60mph
2.8 isuzu engine, Free wheeling hubs, and 1.222 transfer case.

averaging 34 overall commuting 60 miles a day (dont go over 60)

Managed under 20 MPG recently when in a bit of a rush on a 200 mile round trip.

speed is the secret, or rather lack of it

Why such tiny engines in all of those 4x4s? I realize that a well tuned 2 1/2 liter turbodiesel (esp. if intercooled) will put out at least as much, if not more grunt than the average 4 liter NA diesel, and it may be a little more fuel efficient than the larger NA diesel. However that smaller turbodiesel needs to be tweaked to the nuts to do that and is pushed to it's design limits leaving little room for error.

I'm not sure about the record on LR's smaller TDs, but Toyota's 2.4 liter TDs, & Nissan's 2.8 liter TDs are notorious for cracking heads (it's almost a certainty that they will within 130,000 km), whereas both Toyota's & especially Nissan's 4.2 liter I6 diesels (whether NA or turbo'd) are considered to be virtually bombproof. In fact there are a number of Nissan Patrols in Australia that have over 3 million Km on their original (and unrebuilt) TD42 engines.

Having said all that, Isuzu's 2.8 sounds like it might be great IF it proves itself to be highly durable. In other words if it is capable of doing millions of Kms without needing a rebuild.

The Isuzu has a lot of anecdotal evidence to support it as an engine that is hard to kill, hence my interest and choice of it to re-engine my LR.

The 4Jb1 already has a track record of being one of the most durable diesels. they are fitted in everything from gensets, boats, to slew diggers. They are even copied in india and china wherever that size engine is needed.
