convert Rangie SE to LPG can it be done?

Stellvadore · 12th November 2008, 09:02 AM

Okay so the new 2000 Rangie SE is a beautiful car but with it’s 4.0 ltr V8 engine is proving to be destroying my pocket with 17l/100kms around town.
I have been researching getting the car converted to LPG Gas. Keeping it on petrol is not really an option as I generally spend every weekend travelling at least 400kms with 3tone of
Horse flesh and trailer behind me – You do the math and see what my fuel bill is!
My question is, does anyone know of a Rangie being converted? I’d love to hear the failures and the success stories if they exist.

I have been quoted on donut tanks to replace the spare wheel and im looking at only having 52ltrs of usable gas and $4800!!
This seems pricey?
Also is there a difference between Vapour injection and a standard LPG System?

( You must keep in mind I am not terribly mechanically minded)

There are a few guys on here with vapor injection conversions, i think Ron (P38 ) has on his ?

Sequential Vapour Injection (SVI) is recommended for the Thor engine owing to the likelihood of backfire and consequent airbox and MAF sensor damage if the old venturi system is used. SVI is injected into the inlet manifold tracts, the venturi is between the MAF sensor and the plenum.

I had a number of expensive backfires on my old venturi system, none with the sequential. I destroyed two airboxes at a couple of hundred bucks each and damaged the MAF. The previous owner paid $3000 for the conversion 8 years ago. Backfires meant all the hoses were blown off the engine and had to be refitted (as the engine wouldn't run without them). My wife refused to drive the car on LPG even if I was with her. Having the car backfire and stop whilst in heavy traffic, etc, is no fun.

I ended up ripping it out and later converting to SVI when it became available.

There is no noticeable power loss with SVI, there was with venturi.

Around town, you'll get about 240 km range out of a 54 litre (usable) toroidal tank when not towing - a fair bit more on highway.

Hi
I had all my rangies converted.
Not a Vapour injection but lpg none the less.

Currently have 3 scuba tanks in back on floor and retained the petrol tank.
You will use more litres of gas than petrol given the same distance.

A mate has twin under floor and tank in back. More weight but more range.

Where do you live.
There is a whizz here in SA for those cars.

What kind of Rangies?

The reason for sequential on the Thor engine is that the engine shuts off the spark on over run - when you open the throttle, and spark returns, there is more chance you'll get a backfire. On a normal setup, the sparks are still firing so, hopefully, igniting any gas in the cylinders./

Is it true? Dunno.

I am in the Latrobe Valley Victoria.
This decision to put it on gas or not is killing me! I dont wanna stuff my baby!

What model Rangies have you converted over?

Hi

I converted a 82, 87 and 94.
The latter two both had recon 4.6L with Haltech or similar.
The high compression model does like it better and was just as quick on gas. Go figure.

The bottom line is, your running costs will be halved, try and keep your original fuel tank though for range and for when there is no gas available.

The P38 is different, I realise. Vapour injection takes care of that, seperation of HT leads, metal air cleaner box and advanced timing should go long way towards reducing the likely hood of backfires.
