I own a 95 landcruiser 80 4.5lt series with 118,ooo kms on the clock and have had it convert to gass less than 8 months ago! it is the old type mixer converstion but i am increasingly more temped to get the new squentual LPG injected type fitted
-dose anyone know if it can be done on the 1hz engine ( 4.5 80series)
-what is the cost SGI if the rest of the LPG system is already on the car!
-what are the fuel consumtion figuers like compared to the 350 odd kms on the 90 liter gass tank presntly
-where in WA this work can be done
i tow a jet ski loaded with camping gear on my months off and woundering if it will improve the overtaking power and fuel eco
tanks scotty

4.2L 1Hz Diesel, or 4.5L Petrol?? - I have the SequentII version on my 80 1HZ diesel and it hasnt made a whole lot of difference to pre-gas... Not sure of the cost to convert to sequential though... Remember - even though they claim a 20% increase in power - 20% of bugger all (what the 1HZ produces) is still bugger all!!!!!! I cant notice much increase in power or economy at all....

Na it a 4.5 petrol! sorry my misstake!
with the 4.5 petrol the oringal mixer type gass converstion is great for the wallet at fuel stops! but with the new sequentual injection its ment to be even better and get more kms out of the tank!
should of got a diesel but couldnt find one with as little kms on it:)

I think you will find that not much of the 'original' gas hardware will be of any use for an SVI system. Maybe the tank and converter but I cant say for sure; there might be different operating pressures involved.
SVI obviously is heaps better than the mixer ring system for efficiency and power, but it still relies on the basic converting principle of using a heater to convert the gas from a liquid to a vapour. The new generation Sequential Liquid Injection systems are the shiz and you can actually gain power over petrol but those systems are still new and cost a pretty penny.

anyones correct me if im wrong but the gass sytem tanks and plumbing is quite simple in terms of persures e.c.t with a reulator fitted to exterinal of the tank i would expect the the difficult ($$$$$) part of the convertion from your "old" versions to the new would be the injectors manifold and the computerised side of it!
im not sure if the new SVI would use the old mixer!
anyone knows of a company that speciallises in SVI in WA i can in contact with!

I have a pajero that had the old
fork lift conversion done ( mixer ring).
I changed it to the injected style and was much better.
The converter had to be changed and every thing from the firewall forward.
The thing some people do not relise with the mixer style is that it restricts the air flow the the motor thru reducing the diametre so the gas can be sucked in .
I do have more power on gas low down on gas but there was not a lot of difference in power .
With the injected type the computer switches the gass over for you automaticaly and off if you run out of gas and so
forth.

The tank requirements may be different as some have different internal pumps that suit the fuel pressure an injector type system needs as opposed to mixer ring. This is something really only a gas fitter can advise you on.
I had a Romano SVI system fitted by Gaspower Australia but in hindsight I would go somewhere else and get a different system fitted. The quality of the install was ordinary and its an ordinary system - nothing special about it.
It depends on whether your vehicle is a keeper - do you intend keeping it for years and years? If so it might pay you to spend the extra and get liquid injection as SVI systems wont be offered in the future as the prices of liquid injection systems get more competitive.

we are talking just gas injection not liquid gas injection ?
if it is just vapour there is no internal pump it is pressure fed from the gas itself .
PUMP WHAT PUMP!

i didnt think there is just thing as a liquid gass injection kit avaliable!???
i thought there was vapor gass injection! gass in jection straight into the manifold???
zacc did u find that it was more fuel efficent that the ring mixer type? the vapor gass injection!

Only slightly not a great difference but performance was better.
Also with the mixer ring you will loose a bit of power at top end on petrol because the mixer ring reduces the air intake .

I have read some were that you need an oxygen sensor for injected LPG.
If your 95 model cruiser is like
mine they are the series 2 update engine with a new design air flow meter, and NO oxygen sensor.
The LPG installer should have the info on that.
And i have heard reports from taxi operators that the injectors don't last long.
Rob.

anyway did some investagation and i was quoted 4000 for the VAPOUR gasse injection (4750 with a bew tank or 4000 with the tank already fitted) and thay wouldnt even tell
home much the GASS vapour inject would set
us back o
well i think the mixer ring is going to stay with the price tag! thanks all ofr ya input!
