5% is a bit more than significant if you are quoting 1000 mile line haul express jobs or pulling six decks of Tobermoreys or stores in the Top End dirt. The first Cat 3406 in road trains was pre-chamber & was pulling cattle out of Cloncurry and the Gulf to Kidman's in the corners and the Cummins (Big Cam 400) engined gear was carrying extra fuel for the Cat engined Road Boss.

I know that my inquiry was Isuzu 4bd2t; but what about the Cummins 4bt engine and the RRC. Does anyone have experience with this engine? It is the the other variation that I am considering.

CAT do an engine similar size to the 4BD1T, that uses almost 25% more fuel.:D

It's really interesting that most of the newest commonrail diesels have only got about 2% better fuel economy than the 20+ year old 4BD1T. Sure they burn cleaner, meet emissions, have a wider power band and better power/weight ratio. But it's still only 2%.

those things NEVER stop. not real big tho but excelent un attended engines so long as theve got good oil good fuel and the ambient temps is below 85 degrees theyre good to go.

dont quite make 17 HP from the 2 cylinder ones tho.

the 4stroke 4 pots are good for up to about 85 tho.

Sorry no experience with the 4BT.

Isuzu trucks are very popular in Australia, and Land Rover Australia fitted the Isuzu 4BD1 for a few years when Land Rovers were assembled in Australia (following the Aus military requirement for a direct injection diesel). These are the reasons the 4BD1 have a following in Aus Land Rover circles.

There may be problems fitting a 4BD1-T or 4BD2-T to a left hand drive vehicle.

Look at this site Overview for an auto gearbox option. The ZF auto as fitted to Range Rovers will not last behind a 4BD1 - has been tried here and the torsional vibrations kill them.

The Cummins 4BT will be easier to fit into a lh drive rangie. The other engine option is a Toyota 14BT or 15BT - they will be better suited to use in a LH drive vehicle (and are better engines than the 4BD1-T IMHO). But these (Cummins 4BT and toy 14BT, 15BT) are all direct injection.

I just remembered reading some posts about a Cummins 4BT being fitted to a Land Rover in the USA.

Edit: Sorry my memory let me down. Should have been http://www.roverhybrids.com/

Hope this helps.
