Hey Guys,
I am lucky enough to pick up my new SS this week and I am contemplating putting it on to LPG. After reading a few replys to my previous post on LPG, I am curious as to how much I should be lookig at to get it converted and where would be the best place to take it to........
Cheers in advance

Am curious as to why you'd buy a great car like an SS (VE I assume given you said new) and potentially spoil it by putting it on LPG??? :confused: If you can't afford to run it buy something else......
If you really have to go LPG it seems sequential direct injection (I think it's called) is the only way to go, but apparently about $4,000??? I think one of the Vic sponsors does it - APS??? :confused:

Sequential Vapour Injection is the way to go. You don't lose any power or smoothness when running on LPG with this type of system. Consumption figures are only slightly higher than petrol consumption figures. The conversion cost is about $4500-$5000.

$4200 for conversion and $2000 rebate on LPG.
I made a spreadsheet to work it out, and based on spending about $60 a week on petrol, you'll save about $20 a week off your fuel bill, $1000 per year. It will take just over two years to make your money back from the conversion.

yeah defo get it done, i had mu vu ss ute switched over about 4 month ago and after a fine tune on the system (sequential injection) it runs precise as per gas, plus i do 500k's a week n my fuel bill is $40, i get 420k's from a 62l tank, do the math and my gen 3 beats most jap shit for fuel economy :)

Dont forget to factor in the loss of boot space/convenience with either a tank or spare wheel taking space - that may or may not be a problem depending what you use your car for.
Does anyone know of Commodore LPG conversions that put the tank(s) underfloor?

Where did you have yours done Kustomd?
I'm thinking about doing it for my VX, which I'm currently doing about 25,000km a year in. We have that and a Pulsar of the same age, one of them will be traded for a wagon in a couple of years as the family expands and the other kept as the 2nd car (which I'll probably be driving to work as the missus and kids will need the wagon). If the SS is about the same cost to run as the Pulsar, and the SGI conversion has paid for itself in the meantime, it's a no brainer.

I have heard of gas tanks for under the boot in commodores but they replace the petrol tank and are really gay. As if you want to take your car OFF petrol anyway, it is after all what the thing was made to run on.
Since the gas tank won't hold as much as the petrol tank, and as you get less mileage out of gas than you do petrol the gas isn't going to be able to drive as far between fill ups.
Also, you have to do head work if you want to run the engine on straight gas, with duel fuel cars you should flick it onto petrol overnight to prevent the valve seals from drying out.
I'm still thinking about putting mine on the barbecue juice, but i really like having that space in the back seats that i can stick my fishing rods through!

The LPG storage cylinder for the Commodore sedan holds approximately 75L of gas - roughly the same amount as your standard petrol tank (73L). With a well-tuned Sequential Vapour Injection (SVI) system, expect a 10-15% increase in fuel consumption when compared to your existing petrol consumption figures. Also factor in that you will need to run petrol through the engine for at least one long trip per week (to keep your fuel pump from malfunctioning and to stop the petrol injectors from clogging) as well as when the coolant temperature is below 40C (for engine protection). On the upside, if you do choose to install an SVI system, your engine will run as smoothly and as powerfully on gas as it would on petrol, with unperceivable, seamless fuel changeover and retention of all functions such as traction control if fitted. In addition, there is no backfire risk as associated with traditional LPG systems because the gas is injected into the intake manifold adjacent to where petrol would normally be injected instead of at the throttle body.

Gday Everyone,
I am new to the forum but have been reading alot of your comments about several things, as i am in the same boat with my new VY SS and the fuel expenses can anyone give me some advise/costing on the new LPG systems (beside dont get it) and figures on how this will affect my car. Does anyone know of a good dual fuel system than works on the 5.7 or is striaght gas the only answer?
I know its sacralidge but i do long journeys and something gotta give and it wont be my VY SS ive wanted for so long.

I am interested in the LPG Liquid Injection as a dual fuel conversion on my VX wagon. I would go for the donut tank - I think it has around 60l useable.
Can someone advise me of pros and cons of this setup? (I aim to get it done with my 07/08 tax return
Owen ):)

are there any reputable places in melbourne that do this conversion? also any idea how much extra weight the equipment puts in the car when its empty?

Forum Sponsor APS in Frnakston do LPG conversion.

They sure do & do a very good job of it to. They have done My Lx8 Adventra & My VY SS wgn & My brother inlaws BA Xr8
