hi guys,
just sold my discovery this week and in the market for a cruiser.
friend of mine has an 80 series turbo diesel its great cos it gives me everything i want in a 4x4 besides the age. and as you all may be aware the 100 series turbo diesels are IFS which i just dont want to go down that path so could you please let me know what you get out of your petrols and also a heads up on gas. and your general over view of the car advantages/disadvantages.
thanks :D

I have a 2002 FZJ105R GXL auto with injected LPG, unichip, 2.5" mandrel exhaust + pacemaker extractors, and I've added an O2 sensor for the LPG.

With 305/70/16 AT tyres, 3" lift and barwork etc I get 22-24L/100 of LPG and between 18-20L/100 on ULP.

I dyno tuned it with 110kw @ all wheels on LPG, 109kw @ wheels on ULP (few runs within 5 minutes of each other, but fairly consistent).

Overall I like the petrol/LPG combo, it's got lots of power and is happy to do anything I tell it to - but there are a few things you gotta be aware of:

- No O2 sensor means it can run rich as hell most of the time, and you can't adjust it unless you put a sensor and controller in - expensive proposition...
- the solid axle is great, but basically no matter what you do with it, the 6 cyl petrol is THIRSTY compared to the diesel or V8 variants.


Other than that, it's a brilliant 4WD for my needs (3 growing kids plus two dogs) and takes us everywhere reliably.


Next vehicle will definitely be turbo diesel though, even at the cost of RFS.

psst Boris80....wanna buy a well sorted 100 series? :)

the oldman had the 4.5 petrol on gas. Got LPGAS1 to fit a gas system and it was costing them a $100 a week compared now to bout $150 with the turbo desiel IFS. The got it done from new so the expense of the gas system paid it self off in the first two years. But if you flick it over to petrol :shock: :shock: Make sure you put it on gas case they love the juice. If you do get a car, get a straight petrol then get a reputable mob to put it on gas with the valve saver kit for the head. Strong motor but the auto is shit house, clunky compared to the new 5spd auto on the ifs. The oldies had a 90l petrol and 85usable gas. You can get also a 115l gas tank which is 105usable and it hangs a tad lower. They only hit when they standard suspension. They put in 3inch springs and never hit. I dont know why you are complaining about getting an IFS, it will go further then the disco anyway :finger: :finger:
Goodluck, Julian

I have a 7/2000 FZJ105R GXL Auto with 50mm suspension lift, all steel barwork, winch, twin spares, 180 litre sub tank and bog standard motor at 95,000 kms running 265/75/R16 Cooper STs.
Fully loaded but no roof rack, aircon on, I average between 18-19 litres per 100 kms on highway at 110 kph using cruise control. At 100 kph I average between 17-18 litres per 100 kms.
Towing a fully loaded trailer packed to same height as vehicle, same conditions as above (100 kph), average between 20 and 22 litres per 100 kms.
Vic High Country trip (no trailer but empty roof rack) and aircon off used 30 litres per 100 kms.
Under all the above conditions, plenty of power and great off-road cabability.
Hope this helps.
Regards

Yeah no probs bud
I've got the twin belly tanks of 36L usable each - total 72L of LPG.

It leaves the factory tanks untouched, so I've still got 145L of ULP.

I can also replace the factory sub with a 180L tank and end up with 275L of ULP + 72L LPG.

I drive LPG around town, flick to petrol when I'm bored or for about 50km between LPG fillups - I also have the Flashlube installed.

I do 400+km a week so it ends up filling LPG every week, and ULP every month or so.

With the 3" lift and the standard LPG bash plates (they're 3mm steel plate curved to the shape of the tanks), I've only hit them and rested on them twice in nearly 12 months of offroading.

A mate's FZJ105 with the same setup he slipped sideways off a rock ledge and smashed his factory side step to pieces - and only ended up with a couple scratches on the LPG bash plate.

They're strong, and with 3" lift it's only about 15mm lower than the rest of the under-belly anyway.

Very very good vehicle, just at 20+ L/100 it's pretty thirsty.
