Thread: Do up my Rangie classic or get a D2 TD5?

Id happily do a 3.5 v8 to TDi conversion

Mounts need to be welded in. The Tdi mount is quite a simple design so it's easily copied but (in NSW at least) it will require engineering approval.

And so the costs start to add up. You have to factor in such things as exhaust , fuel tank etc etc, and most 300Tdis will have maybe 200-300KK on them. If buying a written off car I recall a fellow club member rolled his 300Tdi on the Oodnadatta track. Dragged it upright tried to start it, whoops bent conrod which he then shut up about. So there is a risk.


Just to compare a standard TD5 auto has a range of at least 800KM not towing.

If you are concerned about range as I am it is the way to go.

My range with 2 jerrys on my camper trailer is around 1100Km or maybe more if I am game.

I tell you it is great and the 40% difference in fuel cost is also great.

Last week I had the honour of driving a mildly chipped D2/td5 over some very interesting (ok, scared the life out of me...) terrain. I really don't think my 95 Classic 3.9 would have handled it with as little fuss. If you could get a 300 to perform as well, I'd say go that route and trash the all-aluminium boat anchor.
(I'm un-impressed with my gutless, thirsty and potentially unreliable & delicate 3.9 V8....)

Personally I have had good life from 3.5's but they are aging badly with far higher mileages than when I first played with them so they are beginning to be a less desirable and thirstier option.

The TD5 I have been learning about while doing groundwork for a Disco purchase and I am familiar with the Siemens injection system which although great as a factory fit I suspect will present issues if used in a swap.
The 300TDi although less refined regarding balance and electric jiggerypokery seems to be the sensible choice if you were going to do a conversion and I suspect that setting up the intercooler properly to cope with a bar or so more boost and some pump tweaking and I reckon youd make up the power ok too

Something that is on my to-do list is to drop the centre muffler off the D1,and to in-large the intercooler it has already been breathed on by MR at Redcliffe in Brisbane and 110 comes up a little under and for an auto I can live with that.

Hmmm, that sounds interesting. This would obviously only help with injected gas setups? Tell me more ...

Nothing to do with injected gas. Standalone LPG processors are fitted to the vast percentage of passenger cars made between around 1988 and 2004 and converted to mixer type LPG systems. For some peculiar reason, many commercials and 4WDs sold in Australia between these years weren't seen as polluting so didn't require O2 sensors and catalytic converters, whereas passengers cars did. All passenger cars fitted with O2 sensors (and cats) are supposed to have LPG processors fitted with their conversions.

All you need to do with a LR V8 is retrofit a suitable oxygen sensor, purchase a new or second hand LPG processor suitable for your LPG system, and put it on. Any gas fitter should be able to do this. You can even fit a microswitch to the throttle travel to disable the processor (giving it a false lean signal by shorting the O2 input) at full throttle, giving maximum power when you need it. You only want to increase economy at part throttle, not limit your power at full noise.

Very interesting, I had no idea.

Thanks for that!
