, the problem with the petrol is the variation in economy when it gets a hard time, I'd go a diesel route if regular travel is in mind, but if its only going to do a couple of trips, then I guess the petrol will suffice

Exactly! What sort of economy do the 101 owners get towing a double axle vehicle trailer???

DaveS, my wife and I drove an oz-built 3.9D 110 from Guatemala-Vancouver. In Wyoming, we had the head winds from hell - about 100km/h. The best we could manage was 80-90km/h on the flat, foot flat to the floor in 3rd (had roof rack with steel boxes), wouldn't pull 4th or 5th. This is about the worst possible situation you could imagine, yet over that leg we only used 16.5L/100km. In a v8 it would probably have been 30+.

I have regularly managed to use only 11.5 l/100km while sand/beach driving. Diesel all the way for me.

A 4BD1T isn't as expensive as a toyo donk.

I cannot speak for the Series 2 FCs but these heavy diesels are really too heavy for the front suspension of 101s as they are designed to carry heavy weights in the rear not the front and tow heavy stuff.

LPG is a better option when all factors are considered.

Yep, lots of LPG bowsers, through the simpson, Canning stock route, Kimberelys........

Yes, lots of outback small towns are absolutely infested with them also.

It isn't a big deal to add an extra leaf to the front if necessary (and yes I know they are parabolics).

But the SIIFCs run normal series semi-elliptics, so they are even easier to stiffen up.

But there is petrol to fill the gaps.

My 101, in the hands of the previous owner, has done all that and more, including Cape York, Arnham Land and anywhere else in tropical and ouback Aust you care to name - all on Petrol and LPG - from 1992 - to 2000 when LPG and Petrol was even scarcer than it is now.

Drop in a old perkins and Five speed gearbox from a older english truck or aussie one.
Reco one from the truck wreakers........problem solved.
Tk befords used a four speed gearbox and heavy duty transfer case in there FWD model and it ran a large petrol torquey motor.
Better still would be a drive train out of a Mazda Or Mitsubishi light 4WD truck,they ran diesels of the correct size as the trucks were rated for 4 tonnes,but they will be harder and more expesive to find in the wreakers.
International also made a light 4WD truck,as did Dodge alot earlier on.
All the above has engines and running gear to take the loads in question and do it without long term trouble with the correct torque spread.

OR

Just leave it original and drive it to its built in design limits and the problem will be solved too.

Thanks for that - yes I have one S2B that is going to remain basically original barring the 3 litre engine which was reconditioned and at a price I couldn't refuse ($600.00).

This other one is for a tow vehicle and can't imagine doing long weekend trips to Victoria, South Australia and Queensland with a vehicle in tow behind a standard S2B. Maybe I should forget my Land Rover and have a Winebago but that's not the point.

What about using a Leyland 698NV and Turner M5A 5 speed? - I have one of those matings on the farm. (Still has the BX851 truck around it though.) Very heavy engine me thinks.

dont know the engine.
Most turner five speeds the gear cluster for 4th and 5th gears can be swapped around so it is a straight five speed or five speed over drive and as old pommie gearboxes go they are not to bad.

The Isuzu 4wd light truck was the NPS. It uses the 4BD1T engine which Isuzurover and others have been talking about.
I believe mazda used a perkins engine in their similarly sized trucks.

The toyota 1HZ is an indirect injection engine which can't compete for fuel economy with direct injection engines. Being a 6 cyl they are ludicrously long.
The 1HD-T is direct injection but the same length and some of them eat big end bearings (cranks too).
The 1HD-FT is the four valve version but still mechanically controlled.
The 1HD-FTE is full electronic control and would be an electronic nightmare to get working. That's once you've managed to make it physically fit.

I own the 4BD1T which is fitted with the Isuzu gearbox (MSA-5G) and LT230. It's a bulletproof drivetrain that's currently taking around 500Nm without complaint. I highly recommend it.
