After reading a number of forums, when it comes to adding more power, diesel conversions are an option. But these conversions are usually done with 6.2L and 6.5L Chev V8s which are around 20 and 10 years old respectively.
Im wondering if (or is it feasible for) the mechanics(who do the conversions) offer conversions to newer diesels such as the Duramax, which is the successor to the 6.5L chev (and has phenomenal specs), or to other diesels.

other big diesel conversions

A Duramax diesel engine, 6 speed manual transmission, no loom, no computer etc will cost you a tad over $20k.
Add on to this the cost of other miscelanious parts, you do the math its expensive.
Having driven many duramax diesel powered pickups they are truely amazing to drive but that engine is big. GM had to raise the chassis 2" to fit the gearbox under the body and raise the hood 2" to fit in the donk.
Probably would suggest a mechanically injected 6.5TD, smaller engine, plenty-o-power compared to Australian stuff and less than 1/2 the price.

No question that the 6B series Cummins is great, but they are pretty heavy - I believe that the complete engine weighs about 450kg. there's alot of steel in them.

This is an intersting point. Techinically, you still have to comply with the front axle maximum weight, and your payload will be reduced by the added weight of the motor.
My guess is that front axle permissable weght for a GQ or Landcruiser would be exceeded with a 6BXXX Cummins, let alone the bar/winch batteries etc already on the car.
Cooling (and intercooling) this motor will be a challenge too. Size of the radiator on a dodge ram is quite intimidating - it would hve to nearly double the size of an 80 series radiator.
Then, if you do fit one and "enhance" its output, the torque produced will be far in excess of what can be dealt with with the rest of the driveline, hence the reason that when fitted to Dodge Rams, they have a D60/D70 combination, and are renowned for killing their automatics.
Oncve the rest of the driveline was "optimised" to suit, you would be trundling down the road in a 3.5 tonne Patrol/cruiser, with stuff all ground clearance becuse of the diameter of the diffs, and find out that you might have been better of putting the same money into a Dodge Ram, and not having all the heartache.
I would love a 6BXXX engined car, but I really think t hat the best way of owning that motor might be in a Dodge Ram.
How about the 4BTA version? A 3.9 litre 4 cylinder? easier to fit and still very very torquey,
Or a late model Dyna motor? (14BT) I think these were available up to 4.7 litre, direct injection, multivalve and exhaust braked. Toyota used a 4.1 version of one of these on the MegaCruiser and claimed 140kw and about 500nm.

btw I have no intention to play with diesel conversion etc in the foreseeable future. This just makes for some interesting reading. Also I will know what to do if I score a nice job.
btw how do you know the cost of the duramax engine anyway?
There are rumors of the new Duramax diesels being installed into Cruisers in Australia (I’m told Marks might be making an adapter) but I think this engine has way too much power for any Cruiser using stock axles, and probably so even with upgraded axles.

Check out the Banks site for details on what this motor is capable of.
Inline six and super strong. Would love one of these. Prolly suit a cruiser too cause the inlet is on the drivers side (australia)

that fitting a large 6 cyl cummins is extremely difficult and impractical in a LC.

The 4TBA Cummins is unfortunately extremely slow
Surely with the same tuning it will be 66% as fast as a 5.9? If we are talking 500rwhp from a tuned 5.9, then 300rwhp from a 4BTA should be possible, no?
