Default LPG CONVERSION ?? ANYONE DONE THIS

Afternoon ppl

Just having a chat with my dads pal in pub other day and he`s had a LPG conversion done on his V70 T5 and swears you can`t tell a difference at all. Apart from more mpg and more money in his pocket with it been half the price of petrol.

Question I have is could a 2002 Bugeye WRX be converted if so how much do you recon you`d pay and does it damage the car in anyway at all ?? Plus can they still be mapped once converted ?

Not gona run out over weekend and get it done but my dads pal swore by lpg and I know he knows his cars as he`s had all types of motors over the years so just wanted ppls thoughts and thought I`d put it to you guys.

Cheers Rich

can be done. I think you need the valve lube add on as well. It will take a lot of miles to pay back though. Most places advertise about 2k to do it. Think it will also switch to petrol on higher boost. Have a look on scoobypedia think there is an article on there.

Thanks for the reply guys it was only a idea and I think it will stay exactley that lol but for that type of money I`d be having to drive to the end of the earth weekly to see any benefits to the pocket didnt realise it was that expensive at all. Thanks for input though. I`ll just have to stop been a tight **** and stop trying to save money at every given corner lol

I've recently had my WRX converted and I wish I'd done it sooner. My fuel costs have more than halved so I should break even 10 months after conversion. It cost me £1600 to get it done inc flash lube. I am now paying 57p per litre and I'm covering the same mileage as I was on petrol.

Most of the time there is absolutely no difference between the two fuels but if I take the engine above 5K revs then it will switch back to running petrol but thats not often so it doesn't bother me.

I understand if the car is remapped then thats not a problem as the LPG ecu can be tweaked independently if required.

Obviously there isn't as many LPG stations around as petrol ones but if you do run out then it will switch to petrol so it's not like you'll be stranded if you run out of fuel.

I've got some photos of my installation if anyone wants to see them.

Mine is a brc system and I'm definitely getting the same mpg. I think this might be down to the LPG kit being mapped on the road for my car whereas the petrol one is the generic subaru map. I was quite surprised anyway as everywhere says at least a 10% loss in mpg.

I will sort some photos out

I look forward to seeing pix, I only use my car for the odd a to b during the wk and on wkend so I dont do enough miles really to justify the outlay but very interested in seeing pix.

cheers Rich

Ok here;s the pics

You can see the new ecu to the left (with the purple bit on), flash lube bottom left, injectors are mounted on top of the manifold, vaporiser is top right but you can't really see it.



This is the only change to the interior, there is a small button next to the fog light switches. It has 5 lights, top one is red or green depending on if it is on gas (green) or petrol (red). The other four tell you the fuel level. When the tank is running on reserve the last one flashes, its quite a subtle flash and isn't distracting. Its not the best gauge to be honest the reserve lasts as long as the other four lights are on. It could do with being re calibrated really but I tend to use the odometer as a more accurate measure. I can do around 175 miles on the tank. There is also a button in the middle so that I can switch LPG off and run just on petrol if I want.



This a 55L tank but to allow expansion I can only get around 48L in. I could of had a larger tank fitted accross the back seat but I use the through load facility quite a bit so that wasn't an option for me. Likewise a tank in the wheel well would have restricted my access to this.



The filler cap, I could of had this in the metal work but I decided to have it in the bumper.



Any questions let me know.

I was thinking about this if I got a Hawkeye WRX or STI especially as there is the tax savings each year, over £200 a year I think on top of fuel savings...but after seeing how much boot space it takes up am a bit disappointed and put off.

you will not get more mpg on lpg its about 15-20 % less than petrol but as you say about half the price so still a good saving and i have had a ouple of rangerovers and you can not tell the difference just runs slightly more quiet but as said takes alot to get your money back

Cars taxed after 06 will drop to £220 a year wont they from £430? Is hat right? That will contribute a lot to the savings. Just that amount of space it takes up is a lot.

wait till the valves regress in to the head and it starts to miss, what you save on fuel will go on repair bills. even the genuine subaru gas conversion you could specify when ordering a new car could not stop the valve regression

Probably you are forgot,i have flash lube kit,which protect valves etc.,because LPG is dry.
Just use google and type it:Flash lube kit


My friend have EVO which happy run 400BHP for 2 years without one issue.And LPG will fit to any car

Hi!!

I have convert my WRX2.5T (black hawnk) of 2008 to LPG...

It appear one strange problem!!!
I don't know how complex is de WRX 2.5T, but I know that it adaptes very quick to the driver and conditions. However since I have my LPG kit installed my car lose power a gas while it works at LPG.

Then I make a reset (shuting off the batery) and the power become to normal!!!!!!

My kit is a PRINS, and bring an electrinic advice to lubrificate the valves!!!!

Do you notice any ill side affects with having such a large tank in the boot? I.e. more tail happy handling?

I think that tank capacibility don't interfeer with the car power. There is an advice in the tank that control the lpg pressure.

My tank is a 64litres one.


The problem of power loss remain.


I have an VSI installed too!!

I've been on LPG since June and I've covered about 9000 miles, things I've noticed about it:

1. I very rarely have to put petrol in any more, I get roughly 2000 miles to a full tank.
2. There is a very slight loss in efficiency, I get an average of 17mpg on LPG, 18 on petrol.
3. Power is lower on LPG, it's not massively lower but it is definately less.
4. LPG stations very rarely have covers on them, if it's raining you'll get wet.

I'm very glad I had mine converted, I wish I had done it sooner as I would have saved quite a bit of money on fuel.

Unfortunately this is not right, you will get a maximum of £15 reduction in VED
