Lpg Conversion

[albi]

Has anyone ever done it?

[Gts25Tom]

Looks like no.

I think this topic has come up before, and no one had done it back then. Personally I don't think it would be worth while. You lose your boot space, your fuel consumption increases, your power levels decrease. For a custom system on a skyline, I'd guess the cost of install vs. the fuel savings would take 2-3 years to pay itself off, which in my mind isn't worth the loss of performance and practicality.

I think by and large, owners of skylines have resolved themselves to the trade off of premium fuel prices and amount of use, with the fact of owning the car itself.

^^ exactly..

Why would you want to convert your skyline to LPG?? What are your reasons to even think about it??

go buy a ex taxi car if fuel is your main concern!!

No one has even bothered to look into it.

You can convert your skyline to LPG and we'll just sit here and laugh..

It's just as bad as buying a Turbo vehicle and converting it to N/A...

Doesn't anybody listen to our politicians and in particular, little Johnny himself?

LPG is a panic attack idea when oil gets expensive, but as is the current situation, little Johnny is throwing $2000 at us to convert to LPG, but there is about a 9 month waiting list to get it fitted to anything, let alone a Skyline.

The biggest problem facing a conversion like this is it's compatability with the stock ECU and not all cars are compatible.

My 1UZ for example, is not compatible and anything fitted with any UZ engine, I know not Nissan, (Landcruisers etc with 2UZ & 3UZ) they have not yet designed a compatible system for this engine derivative.

Now! getting back to the man, little Johnny, he has been making noises for the past 3 years about placing the excise that's on petrol, onto LPG, so in time your going to be paying nearly the same for LPG as petrol, so WHY WOULD YOU BOTHER, when LPG burns so much hotter, as it's dryer and you use 20/30% more in quantity.

Just my 2 bobs worth.

its also like 103 ron fuel and if setup and tuned correctly can run better and hell of alot cleaner. also ghosterider there are several soarer v8's in the eastern states that have dedicated gas setups and a few cars with 1uz conversions running gas too. sure there all custom but nothing is impossible. it all comes down to who u know and how cheap u can get the install done

What boot space?

A guy in WA did it, to an rb anyway, you need a compatible aftermarket ECU and probably him to tune it.

You can do it, they're doing it to XR6 turbos in SA using pretty advanced LPG injection management system coming from Italy.

Get a hold of issue 101 of Zoom, its the June issue for 2006, theres an article about it. The place in Adelaide who can fit them is called Adelaide performance Engineers ph: 08 8277 5688

As has been said, Why would you bother???

The point I was trying to make, apart from compatability is this.

Conversion cost, no matter how or where is about $2000.00 and as LPG burns so much hotter, irrespective of octane rating, it uses more fuel by about 20% and therefore, for the average person it's going to take 2 or maybe 3 years to recover the cost of the conversion and by then, IF the libs are still in power then, you can bet your ass that the excise will be on it and the price will be much the same as petrol per litre.

In the article, they were able to make more power with LPG, and also overcome the increase of fuel consumption by running the LPG in a similar fashion to that of a normal fuel injection system. Apparently the current common design for LPG systems is based on a design founded in the 1950's and is similar by comparison to a carburettor type set up, so as you can gather - is quite inneficient by todays standards.

Having said that, im not an expert on the topic, and am only re-iterating what I can remember from the article

[Ghostrider]

Me niether, I'll get a copy of the article and read it.

But doesn't alter the fact that Johnny's trying to get more dollars out of LPG by applying excise.

yip. i agree

haha yeeepp

I remember something about a standard option in xr6t's where you could purchase an LPG only version from factory. Had different pistons, slightly worse k's per litre as with all gas machines and had slightly less power but lasted muuuuch longer than any conversion ever will... gas converted engines seem to always need rebuilds muuuuch sooner. but admitedly this is based of 2L conversions the old man an I did on some toyota's, read multile hiace vans a few ford taxi's 1 4.1L s pac and 3 * 4L a somethings and a izusu light truck. also had a few done by other mechs an they were pretty practised on half and full conversions which did last a few years.

personly id love to run a few experiments with a decent "gasresearch" setup.

id love to money permitting, be able to go twin 510cfm carbs.

last time i was looking the biggest gas injectors u could get were like 93cc which are equal to like 400cc petrol injectors. so unless u ran gas injection and richend it right up with say a 500cfm gas carb.

i dunno its all theory atm. im still trying to get my mate to set up an account with gas research and there suppliers, which would enable access to all the prinz gas injection parts.
