Direct Injection LPG

[sparkymac]

I am thinking of fitting direct injection LPG to my VT. Does anyone know about it and who to see in Melbourne to get it fitted.

[minux]

Its expensive and usually results ina straigt conversion, meaning no petrol again.

[Kever]

Parnell LP Gas Systems in Laverton fit the Direct GAS Injection Systems.
Quite pricy though, when i last researched the cost was around $3,000.
However, you do get much better performance and fuel economy when compared to normal gas equipment.

LMAO @ Parnell, i would not reccomend having your paddock basher put on gas there, christ, we had a work car put ont here, they put in the wrong injector's then charged us for the right one's, dead set wanker's that group.

Try Smithys in Bayswater. 03 9762 2333 or this link to find your nearest Gas Research Installers. http://www.gasresearch.com.au/fitters.html
Good luck.

Thank you all for your help.
I have had quotes from $3300 to $4000 for direct injection and $1980 to $2600
for a standard system. Now to decide if the direct injection is worth the extra money.

I think you'll find it's vapour injection that you're looking at. Don't bother as the gains aren't there, even if it was cheaper. Just stick with an Impco dual fuel setup. Cheaper and the best you'll get for your money. Or, wait until liquid injection is available. Should be this year I hope. Still wont be cheap but the best thing for LPG. I'm waiting.

and also sent off an email asking a few questions about
propane and automix
and yeh im very interested to getting this
price of fuel and what not.. might be a huge layout at first but in the long run it will be worth it !
then will have over 140lt of fuel to go on long drives !!

Hi Troy,

Thanks for your enquiry; unfortunately at the moment we do not have any
retail product available. We have largely completed the research and beta
testing, and are at the commercialisation stage. We are actively looking for
investors to fund the production of the injection system, if you have any
investment contacts I would appreciate the details.

Our early systems will be straight gas only. Because the system uses all the
self learn features designed into the Commodore's computer, it will adapt to
the different mixtures of Autogas and Propane and will run equally good on
both.

Best Regards

For anyone who is interested i have had the gas injection system fitted to my GEN3 since last November. The system is not and cannot be a gas only system as it still requires petrol to start the engine ,like all dual fuel systems. I would suggest to run either OPTIMAX or similar fuels to aid in preventing the fuel injectors from gumming up.
Since i've had it installed i have done Melbourne-Queensland-Melbourne and numerous country trips with the usual daily city grind to and from work. The system has performed faultlessly in that time. It's operation is seamless and changes over automatically without any noticible difference during the changeover period or during running.
I have calculated that i have saved about $900.00 since the install. I have always had gas cars (5 in total ranging from a Camira to a Prado),and this is the first one that i ran on petrol for the first 4 years that i owned it because the injection system wasn't available until recently. As far as fitting the standard system goes, my advice is [B]DON'T. The main issue with gas, and it's even worse with a vee configuration engine is backfire. Special attaention has to be paid to spark plug and lead condition and replacement. However sometimes the backfire may still occur. My VR and my Prado did it occaisionally. The problem with the GEN III is that is has a plastic inlet manifold that i have been told this tends to blow itsef to bits if the backfire is severe enough. if you have to purchase one of these as replacement then you can kiss any savings from the gas system goodbye...

Hey mate,

Im seriously considering putting that direct injection system on my GEN III, How big is the tank they have fitted to your car? and how many Ks would you get out of a tank? Mine is an A4 and my right foot is quite heavy, so do u still think I would save a considerable amount of money if i were to convert? ive been quoted about $4500 installed up here in Brissy, Does that sound about right?

Cheers.

The tank size is 90 litres with about 74 litres usuable as the tank is only allowed to be 80% full. My conversion cost $4200.00 and i had quotes from $3800.00 and up. The guy who did it for me had done all my other conversions and booked me in straight away, otherwise i was in for a minimum 2 month wait.
Distance per tank can vary depending on driving style and situation. I've varied from low 400's to as high as 600. My fuel economy has varied from as low as 11litres/100 to as high as 18.5 lit/100k. Figure on around 500k's around city if you drive normally. Drive it hard and this will reduce dramatically, as with petrol.
As far as saving money goes, you'll find you use a bit more gas than you would petrol but the price difference more than makes up for it and if you want to drive it hard you don't have to break out in sweat watching the fuel gauge. However the main thing with gas is doing lots of kilometres. The more k's you do the sooner you get your money back. If you do about 40,000km a year the you should get your money back in within 2 years. So before you make this sort of commitment make sure you want to keep the car to recieve the long term benefit.

Cheers..

[deserthead]

You'll get your money back quicker than that if your doin 40 000ks a year.
I've only had gas for 2 months and have already saved 350 bucks.
Averaging between 40 to 50 bucks a tank savings.

Was the direct injection gas conversion done in Melbourne, and if so who was it done by.

[GENIII 227]

The conversion was done in Geelong by Jepsons Automotive. He's directly opposite one of the Holden Dealers. He's a small workshop specialising in gas conversions as well as regular servicing and he's been there as long as i can remember. He's done most of my conversions except one i took to Parnells (DON'T) and one to LPGAS1 in Lillydale.
