LPG and the 2.25 Diesel

[Tank]

Has anyone fitted LPG (fumigation) to their 2.25 Diesel? Can it be done? Does it work? Is there an Installer in Kalgoorlie WA that does this conversion.
Would appreciate any feedback at all on the Pro's and Con's, Thanks, Regards Frank.

Frank - it can be done to any diesel. Personally I wouldn't do it to an NA diesel though, turbocharging is cheaper to install and cheaper to run, for similar power gains.

While my 2.25D goes like a train and has never missed a beat, they don't have a reputation for being the world's strongest diesel. They already run 23:1 compression, only have a 3MB crank... I have been toying with the idea of a turbo on mine, but wouldn't do it to a daily driver.

From what I have heard, an LPG setup on a diesel costs about 4k over here, and you get 3k back from the rebates (while they last).

If it was my car, I would find a 200Tdi (ex defender, not disco), and swap that in. It is almost a straight swap, apart from the plumbing and a few other things.

Frank,
As Isuzurover says, it can be done to any diesel engine, but before you consider a significant increase in power of this engine (including a turbo), think for a moment what happened when Landrover did it themselves! (If you had not heard, the turbo engine was a bit of a disaster, leading to their getting outside help to redesign it into what became the 200Tdi.)

On the other hand, a modest amount of LPG, set up so as to increase power slightly, if at all, would probably improve economy significantly, and certainly clean up the exhaust. But whether it is worth the cost and worth having to deal with two fuels, may be another matter.

The same could be achieved with a small turbo giving 3-5psi boost. Say from a 1-1.5L petrol engine. At those boost pressures an IC has little effect, so is not needed.

However the above is a completely custom setup, and should only be considered by someone confident to do the work.

I have a small Turbo that I was considering fitting to my 2.25D, but wasn't confident that the 3MB crank would take it and still be reliable, I tried to find a 5MB motor, to no avail.,
My son is working in WA and he does fairly high milage in his 79 SeriesIII 2.25D and I figured as the Subsidy for LPG conversion is worth $3K over there, then he should have it done before the Subsidy is pulled, is there a downside to LPG on this motor, thanks to you both, Regards Frank.

As you found out - 3MB engines are near unobtanium here. Afaik we got none or very few (apart from personal imports).

Richard turner from turner engines in the UK built a 2.25D with a 2.5 head and a turbo, but it was just for fun. I have contemplated turboing mine, and may still do it after I finish fitting a turbo to the 4BD1.

The downside of LPG on a diesel is you will increase EGTs, and possibly induce detonation (pre-ignition). EGTs can be monitored easily though.

Tank there is a place in Kal that does it,a woman my Partener works with done her Disco and I want them to do my defender.If you want better mileage put 3.54 diffs in it.It won't be much good climbing out of gullies but it is a cheap option for better savings.Likewise you could fit larger tyres but diffs are cheaper and give a few more MPG.Where's you son working?.

Pat, PM sent, do you have any feedback from your Partner's workmate on the conversion, she happy with it, would you have the name and number of the LPG installer, thanks for your info, Regards Frank.

This mob has an excellent reputation & include an ECU to get around pre ignition issues.
I have been swotting up pretty heavily on Diesel gas installations for work and the company I work for did a heap of research/development from 1999 on substitution, which I've sifted through.
One thing that I've found that its been an evolution and basically only 20% of the data from 4 or more years ago is relevant today.
This has also led to a lot of "old wives tales" about the stuff and problems, which in reality have been eliminated from current ( if you use a good installer) installations.

Have you ever driven a 2.25 Landrover Diesel ??
It might have the power for higher diffs or bigger tyres with a 50% power increase
