Nice interior?

Nothing wrong with LPG, if it does not affect the performance and it will save money in the long run why not?

I am sure if LPG was fitted to a car like Gamers car (unknown if LPG can be done on a turbo car) then I am sure that his car would not be classed as a shed, would it? It is just that car in the ad does look like a mess.

Turbos don't like LPG for some reason. But it's a viable option on the NA.

Search "LPG" on here. There are a couple of previous threads on the subject, including comments from people who fit the equipment.

I think it's because the octane rating is so poo (you lose 5-10% power in an NA by going to LPG) that it dets it's nuts off at any real boost level.

there's a guy over on the aristo forum that's fitted lpg to his Aristo...we'll see how his turbos like it.

not sure how long he's had it in there for but doesn't seem to be any adverse effects from what i can see.

My god, what is going on with them lights

I remember reading about an old drag Nissan that had a 300zx engine in it which was converted to LPG, i'm sure that was still Turbo'd, and didn't hang about either.

i thought that LPG had a higher octane rating, but a lower calorific value (hence the power loss).

That sups been up for sale for along time i've seen it kicking round ebay a few times .

Looks like no one wants it ....... can you blame them ?

I know of someone who runs a fairly big power 200SX S14 and there is not much difference in performance using LPG.

Turbos have no problem with lpg, gsw on the aristo site has lpg on his tt and it runs fine, he does lpg conversions for a living, only problem on the supra is where to put the tank, which is not a prob with an aristo, he does 250 miles on £18!, also it makes more power on gas than petrol about 20bhp, how they are mapped the ecu does not know the difference between gas or petrol, £1800 to convert with best kit and lpga approved may have to consider it

It has actually crossed my mind to convert to.

LPG has an octane rating of approx 105 to 110 RON, possibly more when mixed as a different propane/butane ratio.

Modern port injection LPG systems have no problem with turbo cars. Previous venturi mixer types that mixed the LPg with air prior to the turbos were sometimes a problem as backfire (which some LPG systems do for one reason or another) would blow the turbos apart.

The only limit on port injection LPG systems is the maximum boost you can run. The LPG tank feeds the injectors and has a working pressure of about 3.8 bar at 0 deg C. Obviously it needs a positive pressure to inject, so boost would be limited to maybe 2.5 to 3 bar.

At 38 deg C it has a pressure of 12 Bar, so no problem there!!

I bow down to you fountains of knowledge but I would rather eat my own arm than spend £1800 on an LPG conversion when that could be spent getting a few extra ponies or on the aesthetics of the car inside and out. A lot you could do with that money that sure beats the living cr*p out of an LPG conversion I can kind of understand it on the Aristo due to the family dimensions of the car itself but this is a Supra.... It's supposed to polute the world and cost a fortune to run otherwise they would be driven by Chavs and "Green aware" politicians and lets face it neither of them should ever be aloud behind the wheel of a dream!

Rant over!

I was talking to an employee of a LPG conversion company. What I did not expect was the variable quality of the LPG at pumps in filling stations. Apparently most of the gas sold for use in petrol station is scavenged from gas in other tanks.The company that my friend works for, actually sells gas back to the gas supplier. Every vehicle they work that requires tank tests has its gas put into the scavenge tank. Very regular filter changes are essential to keep LPG cars on the road. When I saw the inside of the LPG filter on my landrover I could not believe how much crap had been filtered out in only six months from a substance that I thought was invisible.

Unlucky for me my gas ECU has given up the ghost. The company that supply this particular system do not acknowledge that any of their systems can fail, so forget any warranty, they just wont honour it. PM for maker as I don't want to get sued.

My Supra is LPG!!

Although I don't use it, there is a tank in the boot that is good for about 60 - 70 miles.

How much would it cost in gas to do the 60-70 miles?

Not that i'm planning on getting it done, just interested to know.
