I WANT TO FIT THE DIESEL GAS SYSTEM TO MY 1999 GU NISSAN PATROL DX THIS IS A NATURALLY ASPIRATED DIESEL 4.2

HAS ANYONE HAD THIS DONE TO THEIR WAGON ?

CHEERS

I've actually been warned about doing this, was going to do it to the cruiser...

From what a few people have told me, its not much different to tossing some ULP in the tank regularly.

The results on a N/A 4.2 are not really worth the money,only difference you will find is marginal power increase and better fuel economy at best.

Results on turbo 4.2's is good.

Saw it for the first time on the weekend. If i ever get a GQ it'll be one of the first things i'll do!

I was very impressed! Wasn't too much from wat the dude was saying and he can't see why it's not more popluar!

His was a N/A 4.2D GQ DualCab

still a very unknown quantity I think, not enough people know ALL about it, and long term effects on engines etc.

Gooday, i have a 4.2 turbo wagon on Diesel/ gas , fitted last year,i am cheezed off i did not do it a long time ago. Without a doubt, more power, quieter motor noise, better economy, cleaner oil. No complaints at all.

How much did it cost to get set up? Did you use the government rebate?

Cheers

weve done a few 4.2 patrols, both n/a and turboed. id definately recommend getting a turbo first as the results of diesel gas without turbo are marginal on that engine.
roughly you'd be lookin at $4500 and if privately owned you can get the $2000 government rebate

i am a diesel gas australia fitter. we have had grate results with the 4.2 n/a and the turbos. actually if its a diesel we have had grate results. there are no bad points only good. you get more power more torque better econnomy quieter running engine less oil changes cleaner engine oil longer life of the engine and cleaner emissions. it costs $4300 on a gq if you dont have a second diesel tank if it does you would be looking at $4500 which includes moding the exhaust around th tank. i have it on my 2.8 GQ at its the best thing i have done. if you want any more info you can phone 07 3375 6377

strangely enough, a guy on another forum was looking into this for a while, got all his facts and figures straight, cost was $2500. he thought about it and the next week the government introduced a $2000 rebate!!!! he thought sweet, the govt pays $2000 and im only out $500. rang up to book it in,(remember, only 1 week since he was quoted $2500) and he is now told $4500. sounds strange that the parts/labour increased over night by $2000 JUST when the rebate came in..........

I see a couple of gas fitters have replied here, can any of them shed some light on the subject?

mate i wouldnt say thats too funny, at the time the rebate first came out, i was driving a 1974 LWB F100 with a worked 351, i was slowly going broke due to fuel bills lol, but anyways i had been enquiring about getting it changed to gas and was i had got 3 qoutes ranging from about $2400 - $3000

2 weeks later the rebate came through, i went in to book it in and all 3 shops had now added $1000 or more onto the price..

That's exactly what happened. Even the fuel companies are cashing in on the popularity of LPG.
Same thing happened to cause the housing boom. Government gave a first home owners grant and the prices skyrocketed. People thought, if the government are saving someone $x then I can ask $x more so the persone doesn't actually spend more but I get more.

I had a quote of $3000 for our work ute (Rodeo V6), and its now $4500.

I spoke to a feller from Diesel Gas at the farming expo on the weekend, and he said for a GQ N/A wagon it costs $4200inc GST. Apparently this price includes re-routing the exhaust in the rear half. A dyno sheet showed and improvement from stock 82-83HP to around 100HP with the gas on. The turbo diesel dyno's were just bloody rediculous, a actually had trouble working it out cause the "before" and "after" curves were almost on the next page.

The Diesel Gas systems are controlled by a microprocessor, and the demo car at expo was a N/A 4.2 diesel Cruiser trayback. The bloke said he's got three different injection maps programmed into the microprocessor, and that the gas was injected at 7psi(not too sure how big boost systems are setup though...). Looked like a pretty simple, neat setup. The multiple gas injection mapping was pretty impressive too!!

a word of advice, do some research on LPG and excise tax, I read somewhere a while ago the gov was planning to reintroduce the tax or increasing it on LPG in the first half of 2008. Shows govs TRUE support for moving towards cleaner fuels.

True. I remember reading up on that a while back. Apparently the price of LPG has no bearing on the actual manufacturing costs at all, but they actually set the price of LPG by setting it at a certain percentage of the price of standard 92RON unleaded. Greedy pricks.

wouldn't supries me, since LPG is by product of producing petrol, for years they were just burning it off as they had no major use for it.

the only real cost is capturing and storging it.

Can the SD33T from the MK series be put onto gas?
It is tuned/ic'd/boosted atm and looking for more grunt...fuel economy is good atm with 550/600ks to 67l but wanting a bit better!

cheers!

mate they have been doin this on trucks in NZ for about 20 years and have proven motors last longer run cleaner use less fuel. now for the but and it is a big but i am in touch with people in gov dep and know for a fact that the gov are going to bring in tax that will bring lpg prices up near the price of petrol by 2010 nice ha . u would think that they would wont to promote the only fuel that makes both diesel and petrol motors run clean that we have but all they wont is money

Thats bloody disgusting isn't it?! But really, what more would you expect?? Has anybody tried to organise a national fuel purchase strike? Imagine that for a whole day...... i bet that'd make them sit up and listen.

Coxy

yes was one getting around it was today mate gess u did not hear of it

Nope. Must've missed it. Doesn't matter though - i have one every two weeks, usually the day before payday.

gas is for cooking

Yep gas is for cooking on down the road just like oil is for frying tyres and hair dryers are for girls
