How do you drive these things!

It doesn't affect low range, as it's only the high range gears that get changed.

Downside is on steeper hills you do need to ride the clutch more to take off due to the higher gearing.

Upside is it will do 100km/h comforably in fourth gear, and fifth cruises very easy at the same speed. It pretty much sits perfectly for the turbo.


However I am running maxi-drive reduction gears which make a huge difference as well.





Edit - I wouldn't run anything but standard size tyres on it though, as you'd be putting too much pressure on the clutch, especially towing.

Sorry I forgot about the gears.

Without breaking out the calculator they'd probably give you much the same gearing in high range as a set of 33's so we're probably pulling much the same revs everywhere.

I actually like the gearing on the highway and in the hills around here with the 255/85's, even when the engine was stock I reckon it suited it better. (excepting first and towing or hill starts)

As you say 100km/h in fourth is great for hills or overtaking, although a B-Double passed me the other day going over the range here as the speed slipped to just under 100km/h :o

Third is more useful too, I can pull 90 in third when needed, and I have seen 100 once or twice but I reckon that would be close to the governor and the engine will pull just as well if you change gear at 80-85.
Before the 3" exhaust it hit the wall at 75-80km/h in third gear, just too much back pressure at high flow/revs with the standard 130 system.

I'm not kidding though when i say I was less than impressed with the performance when i first got the 130 back in '02.
There's a stretch of Highway between Scone and here that is just a gentle but definite incline of about 5km long, and i used to struggle to maintain 100km/h on it.
If there was a headwind the speed would drop to 95, then 90 and I'd have semi's up my clacker :eek:

Paul the director of DLS when he stayed at my place a while back said that going for the disco transfer gearing was a good idea for long runs i.e: Most of Australia lol.
And as Mr Wilson indicates, It makes no difference to the low down torque I am considering this for the 130 soon

I got used to mine now and love it! I find it sits on 100-110 comfortably and fairly smoothly too. I got my rev range happening now and I just find it's best to make quick smooth shifts between gears so the revs don't drop. I was in third before I got to the other side of an intersection at the start of the week :-) Now I can moderately keep up with the traffic from the lights. Love my Landy!

wait till ya get the pump massaged.

I'm still not convinced that it 'doesn't' affect longevity of the engine though. It's always been a concern of mine and yes I understand EGT's etc.


I just figure that they got it right in the first place and I'm never in that big of a rush driving the old girl.....

Thats part of the charm for me. It makes you slow down and take your time. I don't flog it or rev it hard, just a nice even smooth change up through the gears.

What is pump massaged mean? (nearly afraid to ask!)

Chris, the 200 is a stronger engine than the 300 in that department IMHO. They are under fuelled and under boosted from the factory. You can easily and safely up them to 15 Psi from 11, with a bit more fuel at the right time, which CAN make them slightly more economical as they can spend more time in the higher gears.

A great and underrated engine.

Re-adjusting the fuel injector pump.

all pumps leave factory A (which isnt a rover factory) in a standard configuration +/- a tolerance

all engines leave factory B in a certain trim which will be +/- a tolerance with a pump from factory A bolted on. so long as the engine makes spec power when run up they dont touch it, some go over some just make it. Add to that the fact that every driver and vehicle configuration is different and there is scope for tweaking the motor to perform differently. People who drive like me and drive them like its a truck prefer an engine that pulls harder down low which is great for towing and low speed 4x4 work, people like the stig who wring the neck out of things prefer an engine that makes it all up the top end for maximum speed and acceleration.

With a compensated Turbo diesel like the tdi's the power output of the engine can be "massaged" to suit the driver and as with all turbo diesels if you drive it nicely you could set the engine up to produce several hundred horses and mutiple wheelbarrow loads of torque so long as you dont have the engine deliver it (as in you dont bury the boot) then it wont be detrimental to either your engine life or fuel consumption.

I think I'm happy with my old girl the way she is :)
