Thread: 2003 V8 & LPG

Our 2000 D2 was converted to run on LPG in June this year, its using an Italian made vapour sequential injection system made by Tartarini and fitted by Range-Rov Automotive in Vermont.

There are 2x tanks that replace the original 90 litre fuel tank and give a useable 80 litres of LPG and a smaller 50 litre petrol tank is installed in the RHS wheel arch. With this setup it should provide 350KMs on LPG and 250kms on Petrol

It was installed by Range-Rov Automotive which are Melbourne based

Cost was $5800, less the Government rebate of $2000, so $3.8K all up.
The rebate takes 10 days from start till you have the cash in our pockets, but they have now dropped the rebate to $1750 as of the 1st of July and it keeps dropping every year from now on.

You need to find an installer who does Landrover, don't go for a generic installer its just not worth the risk. The install is pretty full on with even things like the tow bracket needing to be modified which requires engineers cert etc.

There are lots of stories of catastrophic engine failures after LPG installs because it wasn't done properly and the motor runs to lean...

Does any one know how common this is?

These sorts of stories are what's holding me back at the moment

I've considered the tank set up you have but I'm leaning towards the manifold tanks in the back.

More range

Thanks for the info

This is my take on all of it..

Basically the "Thor" 4 litre V8 is susceptible to slipped liners, but it is pretty much unheard of in any of the older motors eg:3.9, 3.5 etc.

There's more than a few theories on why this is, poor quality control, blocks being turned out to fast to keep up with demand and not given time to rest before assembly.... etc

Personally i think its a combination of things-

1. The motor runs hotter than previous generations for emission reasons
2. The motor runs leaner also
3. The temperature gauge is useless and will show "normal" for everything and when it does show hot its to late.

It seems that slipped liners always occur after an overheating incident, even if the driver isn't aware that this has actually occurred (re:temp gauge)

Whilst i was having the LPG installed they checked the cooling system on my D2, they told me that almost half the radiators they check on D2's now are blocked (this gives rise to the OAT coolant debate once again)

So in my opinion does LPG cause slipped liners?....Nah

Can it contribute to slipped liners?...Yep...A poorly installed LPG system can run lean or lean out at higher revs.

Make sure you check the cooling and make sure your o2 and MAF sensors are all in good order. Spend the extra $ and get the install done by someone who knows what they are doing and you should be fine.

LPG vapour injection is definitely the best if you can afford it, the system I use (Zavoli) can be programmed to run a percentage of petrol under full load, and drops back to petrol if LPG pressure drops and is unable to supply enough fuel. So providing its properly set up it has no engine reliability issues. As for tanks, all locations are possible, including some ducky little sill tanks which hold 19 litres each. Brown Davis in Melbourne has a nice petrol tank to put in the right rear corner, if you use 2 underfloor tanks (70lt) in the rear. I posted a few pics of conversions I have done (in Adelaide) some weeks ago.

Thanks mate. That's some good info

Shame I'm in Brisbane or I'd get you to install it

Sounds like a perfect excuse for a road trip

I thought that myself

very tempting that's for sure.

I too am looking at getting a D2 and would like it on gas.

I have had 2 d's1 on lpg and recommend them. Though I see the d2 generally need the SVI. A lot of the post recommend a good landy LPG installer for their wisdom and relability.
I'm in the Illawarra (NSW), does anyone know of any LPG installers in this area or the southern sydney area, who have converted the d2?

I know i have seen recommendations for Bruce Davis Performance Landys at Annangrove and Diesel Gas Technologies, but thats a bit of hike, which I'd like to avoid if possible.

Any good advice welcomed. (as I dont want to be a test mule, for somebody who wants to have a crack at it)
