Lee-Anne Posted May 12, 2006 Share Posted May 12, 2006 Im sure you all know how much petrol Supras drink even N/A! Has anyone ever thought about it? I have had a few quotes and it would cost around £2000 but you would make your money back depending on mileage in a year or 2. Would save having 2 cars which means 2 mot 2 servicing 2 road taxes! Also seems a shame to have the Supra and only drive it at the weekend! Also im sure you get cheap road tax as well! Link to comment Share on other sites More sharing options...

Whitesupraboy2 Posted May 12, 2006 Share Posted May 12, 2006 mkivstore.com has definatly done one. Martin posted about it. PM lucifer (he will have a thread in his section for full screen name and see how much he will do it for ) Link to comment Share on other sites More sharing options...

michael Posted May 12, 2006 Share Posted May 12, 2006 I'd rather spend the £2000 on petrol and just enjoy myself TBH Link to comment Share on other sites More sharing options...
Gaz6002 Posted May 12, 2006 Share Posted May 12, 2006 am I right in thinking you can only do this to standard cars? Link to comment Share on other sites More sharing options...
Mike Posted May 12, 2006 Share Posted May 12, 2006 I'd rather spend the £2000 on petrol and just enjoy myself TBH so it does kill performance...? my sister just had her ML Merc thing done and she didn't notice any change..?! that said it weighs like 3 tonnes to start with so probs drives like a dog anyway....

michael Posted May 12, 2006 Share Posted May 12, 2006 I've only experienced it in a factory dual fuel Astra - that feels less responsive on gas but it doesn't feel amazing on petrol so it's hard to say It uses a lot of LPG compared with petrol so the savings aren't as magical as they first appear, yes the fuel is considerably cheaper but you use more of it... there is always the risk of the government hitting it with tax too...

Clarkey Posted May 12, 2006 Share Posted May 12, 2006 I can't see the point of converting to LPG. The performance of: Singles might well end up like TT's. TT's might end up like N/A's ... and N/A's might end up - like your Astra Michael. Link to comment Share on other sites More sharing options...
jamesmark Posted May 12, 2006 Share Posted May 12, 2006 i looked inot this and from some of the sites i looked at, all of them had the same conclusions and thats that there is very little difference in performance, but you get nearly the same mpg in some case's, when is half the price of petrol so there is a point but i never read anywhere about turbo cars Link to comment Share on other sites More sharing options...
Wez Posted May 12, 2006 Share Posted May 12, 2006 I think one of the BTCC cars is running LPG. If tuned properly I cannot see an issue, all you are doing is creating a controlled explosion, as long as its ignited to its maximum effeciency there should not be alot of difference.

Terminator Posted May 12, 2006 Share Posted May 12, 2006 Cheaper road tax I wish, I have a 4L Disco with a conversion makes no difference to tax. I can feel a difference in performance at the top end. But I do tend to drive the nuts off it. With a decat and a few other mods it is pretty quick for a 2+ ton box. You dont get the same miles per litre either, you get less but as it is lower cost it does save money on fuel.Alot of the advertisers for LPG conversions make claims that are based on ideal condition, bit like 0-60 times. On long runs where LPG is best, the 4L cost as much as 2L car on petrol if driven sensibly. Unfortunately I can press that gently on the throttle, I have a problem with my right foot. If you are looking for savings and are prepared to drive carefully you should see pay back in 2 to 3 years depending on anual mileage. Link to comment Share on other sites More sharing options...
RedM Posted May 12, 2006 Share Posted May 12, 2006 The cost will go up as more people convert or but cars already enabled. Look how cheap diesel used to be. Link to comment Share on other sites More sharing options...
dangerous brain Posted May 12, 2006 Share Posted May 12, 2006 Its also rated at a bit above 100 ron so theoretically its gonne be better against the det monster in tuned motors. The biggest problem you will have is finding somewhere to put a tank big enough to get you more than to the shops and back. Link to comment Share on other sites More sharing options...
sarjo Posted May 12, 2006 Share Posted May 12, 2006 The cost will go up as more people convert or but cars already enabled. Look how cheap diesel used to be. Actually RedM, the government cant control the tax it puts onto lpg, we have to stay in line with Europe on that one, so price will always be cheaper - or so I have been reliably informed I've got a 3.5 litre 4x4 which I had converted. To fill the tank with petrol cost me £70, to fill up with lpg costs me £26, and I get very, very similar mileage. Will get my £1800 outlay for the install back in less than two years Link to comment Share on other sites More sharing options...
Lee-Anne Posted May 13, 2006 Author Share Posted May 13, 2006 It makes no difference to performance its better for the engine and although you do use more of the autogas than petrol coz its so cheap it still saves you money. The tank goes were the spare wheel sits and Im sure will be big enough to get you to the shops! I dont think it can be done on turbos or not TT's anyway as the power is too much. The government has froze the price of autogas for the next few years I think but anyway if it goes up it wont be much compared to petrol as its not refined from oil, it will save money even if it goes up coz theres no way it can ever cost more than petrol spec the way petrol cost is increasing! Ive asked on a few other sites and they have nothing bad to say about it. We plan to keep the supra and will save money doing that even if we only drive it at the weekend considering a full tank gets about 250 miles!

i-macca Posted May 13, 2006 Share Posted May 13, 2006 The government had frozen tax hikes on Autogas but that bad has been taken off now, so it's just a matter of time. As soon as they realise it's getting more popular and that they are losing out on money to it, the tax will very soon rise to be inline with petrol and diesel.

Thorin Posted May 13, 2006 Share Posted May 13, 2006 It makes no difference to performance Must have been something wrong with all the car's I've driven with LPG conversions then. There is a difference, it's not major but it's there. Not too sure it's "better" for the engine either, the engines were designed to run on petrol. We used to have a lot of problems with the LPG cars (cutting out going round sharp bends was a fun one). I would never do it on a performance car.

Lee-Anne Posted May 13, 2006 Author Share Posted May 13, 2006 Here is were I have got my information from, I dont think autogas will ever be the same or more expensive than petrol. http://www.greenfuel.org.uk/ How will it affect my car's performance Modern LPG conversions suffer no noticeable loss of performance. Engines will run smoother and be slightly quieter. For more details, see What is LPG? Will it damage my engine? On the contrary, the LPG conversion will reduce engine wear. LPG burns cleaner than petrol. This means less emissions out of the exhaust and less carbon deposits in the engine. These deposits are very abrasive and can contribute to engine breakdowns. The oil and spark plugs will also last longer. For more details, see What is LPG? What is going to happen to LPG prices? The Government has committed itself to reducing pollution. The environmental credentials of LPG are proven. Therefore it is extremely unlikely that the duty differential between LPG and petrol and diesel will be reduced. For more details, see What Is LPG. There would be no point in converting a non performance car, depends what you say is a performance car, as they are what uses most petrol so would be more worth while converting? I dont think it would be worth converting a smaller engine car considering the amount of petrol they use anyway. There is 2 systems you can get single point is the older which would not be recommended as its prone to backfiring the multi point is the way to go from the garages I have spoke to.

Lucifer Posted May 16, 2006 Share Posted May 16, 2006 Yes we do do them, the cost is £1800 and NA only. Link to comment Share on other sites More sharing options...
andrew7 Posted May 16, 2006 Share Posted May 16, 2006 We have just had long conversations about this on the LSOC (Lexus Soarer Owners Club) One guy does have a TT with it. Another has his V8 converted. He reckons he is getting the equivalent of 38 mpg (in £ terms) with a slight loss in performance, which he can nullify if he wants by switching to petrol when he needs to (switch on dash). Lots of discussion about engine wear etc.... Link to comment Share on other sites More sharing options...

cashpoint Posted July 22, 2006 Share Posted July 22, 2006 Thought i'd bring this back as it can be done on a turbo as I just found this on ebay. http://cgi.ebay.co.uk/Nissan-200sx-S14a-Duel-Fuel-Petrol-LPG_W0QQitemZ220008179121QQihZ012QQcategoryZ18238QQssPageNameZWDVWQQrdZ1QQcmdZViewItem So it appears it can be run on a turbo.

Guest B4ATY Posted July 22, 2006 Share Posted July 22, 2006 Have been a couple of reputed very successful conversions done on vr4's and documented on the vr4 website, - and they are developing 286hp as standard. Link to comment Share on other sites More sharing options...
