Thinking of converting my P38 to LPG??

[RickP38]

Hi all, as the title states, with petrol prices souring, I am very seriously considering converting. This is a big step for me as I have always been against LPG, however times are changing and if I wish to keep my much loved Rangie so must I! My knowledge of LPG is very limited so I am asking is if anyone else has made the switch, is it worth it, experiences, long term effects etc....

My cars details are as follows:
2001 P38 HSE 120,000K 4.6l

I am looking at spending the extra money and going with the injected gas system.

Thank you in advance.

Hi Rick
There's alot of info been posted on this subject
Try this link ... http://www.aulro.com/afvb/technical-chatter/29439-lpg-coversion-discovery-puzzle.html?highlight=gas+setup
about the 8th comment down is the story on a P38 ...

Do you want to set it up for actual 4WD or just keep on the tarmak .. cause there totally different setup's to consider :)

Gday Rick,
I have just booked my P38 4.6HSE in for a gas conversion, after a bit of researching it seems that all the installers that I rang would only do Gas injection for the P38. If you are in WA I can give you the name of a company who was recommended to me by several other gas installers. Its a bugger that I have to wait until mid September to get it done as they are that busy!!

I believe gas injection may be the only option for a 2001 (Bosch based) motor.

I have a blend system on my 97 GEMS motor.

It works very well, and saves a lot of $$$.

If you're planning to keep the car for a few more years, I'd say go ahead and do it.

The main consideration is what size tank you get and where you put it. If you get a traditional tank and have it in the cargo area, obviously you lose about half of your load space. If you get a donut tank fitted in the spare tyre well, you lose the spare tyre.

Mine is a traditional tank mounted on 2 rails at the back of the cargo area. I still have full access to the spare tyre well, and I have built a cover out of MDF to surround the tank and finished it with matching fabric trim.

I also have the dog barrier, which means I can load soft stuff up on top of the tank.

Good luck

Dave

Where are you located Rick?

My P38A is running and injected LPG system. I can't pick the difference in power when it changes over.

[RickP38]

Thank you everyone for your replies and advice.

mike 90 RR, I followed the link and that was full of useful information thank you. I do a lot of heavy towing with it (tow a race car) and we also like to get away in it, we are planning a trip up the Birdsville Track. Will this type of work make a difference to the setup?

strange_rover1, I'm in SA. Can't believe you have to wait till sept!! I've got a bloke here ready to do it basically straight away..

adm333, I think you are right, injected is the only option. In regards to the tank, I have to do some research into the volumes but I think I will go with the donut style and put a rear tyre carrier on the back. (I saw someone arranging a group buy on here a while ago..)

p38arover, I'm in SA. What you are saying about not being able to tell the difference appears to be a common theme.

Once again, thank you all for the advice so far :)

Rick I beleive the doughnut tank that I will be getting has a useable amount of 72 lt, which is pretty decent. I am also going to be doing a new rear bar with spare wheel carrier.

If you live in SA, there is really only one option for LPG here.
His name is Jilden Reichart and lives in crafers West in the hills.
Works from home and is in the phone book.

An absolute whizz. he is an engineer an does the job in absolute perfect manner. Uses copper pipes and a great install.

He has done two of my 4.6 RRC and is doing my disco in 3 weeks.
Mainly does Land Rovers and is well known.

Can forward you his no when I find it.

Tell him I send you (Frank).

Best of luck.

Thanks Big Guy, i'll look him up.

Let us know how you get on.

[p38arover]

I've still got the venturi system I took off my P38A. I have the converter (Landi Renzo), the venturi ring, the tuning thing that adjusts the LPG flow, and a vacuum-operated economy device, and the LPG/petrol switch gauge. All for sale. I've also got the mounting frame for a 90 litre tank for the rear of a P38A.

The tank has been reused.

The govt. will still pay the $2000 rebate even if second hand LPG parts are fitted.

All the above (except the frame) could be used in any RR up to the GEMS.

Just to throw some petrol on the fire,

This Probably won't suit your needs, but myself and some guys on the Rangerovers forum are looking into the new Liquid Injection and Flat Gas Tanks.

The LPi system does away with the conventional Converter, and a pump in the tank, pressurises the system to 5bar above tank pressure. The Liquid is then fed into a fuel rail and is injected directly onto the back of the Valve Stem. Apparently its a massive step forward compared to conventional gas systems. It also has a side benefit of cooling the air as the liquid changes to a gas inside the head. Considerable benefits in fuel consumption and power. Prices are expected to be only slightly more than Gas Injection. There have been a few falcons getting around for a couple of years now as test cars, and no problems reported. From what I understand is that it will start to become more widely available towards the end of the year, when an OZ designed injector is being released.

The other thing is the flat tanks by PPI which are made of Alluminium.

I too am looking at LPG but will wait until hopefully this new system is proven, as I have bigger things to do to the car first, like a block rebuild.

Apprarently, there is a really good vapour injection system for the BOSCH motors, which actually increases power etc... but is more pricey. Deacon Auto told me when I was looking.

Good Luck

[r.over]

They originally had liquid injection before vapour injection. But they found the cold gas cracked the pistons. I wonder how they got around this issue or are there modifications that have to be made to the motor.

[81stubee]

Not Sure about cracking pistons, this gives me something else to chase up. I would guess its due to the advancement in the injectors, being able to meter a smaller amount.

The amazing trick i've found is that apparently the one injector can run both fuels through it, they replace the OEM injector with a new one and just switch the supply to the fuel rail. I'm still skeptical about this.

hi mate, i just got my 96 model rangieee converted, got a 90L donut tank under my spare wheel. i didnt go with the injecter because its cost to much for me but the system i got work fine and only cost me $3350. the guy that did it know alot about it plus he got a rangiee tooo. :D

im happy with mine so far....:)
