I am interested in a 94 3.5L v6 pajero exceed. Does anyone know any problems with these major that is. I would also expect it to be pretty poor on fuel so I would cosider a LPG conversion. Does anyone know what the tank options are.
Thanks I will appreciate any information.

G'day,
Sorry rusty I don't know that particular pajero but I do have some observations on gas conversion/s. I own a '91' GQ with both Unleaded and LPG, the fuel economy on gas is pityful and not much better with Unleaded but with the price of gas expected to double(with the introduction of the new fuel tax) I'm getting rid of the gas. I expect with the removal of all the plumbing used in the gas conversion I will be able to tune my GQ to such a level I can expect not only better performance but much better fuel economy.

Double! Where the hell did you get that from?

Now the Facts: From July 2008, excise will be phased in over four years for alternative fuels such as LPG and ethanol, starting at 2.5 cents per litre.

The final rate will be 12.5 per litre in 2012.

Talk the talk, you know the 'facts' but just as LPG has more than doubled where I live in the space of 8 years, by the time 2012 comes around I will bet you $1 the price will be $1 at least.
Nothing I repeat Nothing (especially fuel) ever goes down

You may well be correct in which case I'd expect the price of ulp to be pushing $2 but I'll take you up on that bet :)

G'day Rusty,
I used to have a Paj with with gas (1999 3.5 lt). Sold it after having the motor rebuilt after only 40,000km. May not have have been the fault of the motor, but of the installer. I fitted a snorkel after which the same installer recalibrated the gas to run with gas (extra intake pressure), I had it regularly maintained and serviced by one of the biggest gas places in Melbourne but alas it bleep itself. From that day on I'm of the opinion that unless a motor is designed and "built" by the factory (not some seemingly hick that the dealership gets a good deal from) to run on an alternative fuel then I'm not stuffing with it. I now own a diesel car and couldn't be happier. You can get diesel anywhere, try that with gas. thre are also other advantages. On the Paj we had about 60 lt useable gas and 60 of petrol. F-all range once the gas has gone. Patrols of the type above are quite engines for gas conversion as far as I know, sure they don't get real good consumption but show me a Patrol that does (petrol that is) We used to get about 15lt/100km (petrol) or 17lt/100km (gas) on the open road. Cant remeber around town.

Rustyglen.
The pajero is a good vehicle with no major problems, but don't put it on gass. The cost of the conversion and the extra motor repiars will be more than the saving in fuel. The gas tank is to small and you will be constantly filling it. If you drive the paj at modest rates it will return very good economy. Eric.

I'd go along with that. The 94 DOHC the most powerfull Pajero ever is a superb engine that shouldn't be messed with. The handbook will tell you if it's the so called LPG compatible engine but don't do it. The head will cost you big bucks for any work. 14L/100k

I think it wasn't until 96 that Mits recommended gas.

Rusty

I would check with Mitsubishi. As I understand it no motor pre 1997, will handle a gas conversion. Head and valve problems. In any case why stuff up a perfectly good donk, with gas. Moreover, you achieve no greater fuel capaciy as they have to remove the fuel tank and replace it with a smaller one. Other option is to do what they do with land Rovers is to place it on the rear floor and hence you lose space.

Good luck, good motoring.
