LPG Conversion on my WRX
Discussion
Don't they start from about £1200-£1500. I don't see a problem with doing the conversion but wouldn't you have been better off just having an economical car for everyday use in the first place.
I know there are a few examples of LPG'd WRX's but not many. They are quite rare and i think there are reasons why
My issue with that is you're carrying a big heavy LPG tank and they are pretty heavy when filled, plus a petrol tank, again heavy when filled. IMHO you don't buy a WRX or STi to have an economical car. Not a bad way to extend the range of your scoob a bit but that's it really. Still a lot of weight to carry around and i'm sure it has to affect the handling as well as overall economy somewhere along the line.
IMHO i wouldn't bother. Buy a diesel instead. I've got two as well as my sportwagon

In the world of cheap landies and rangies a new conversion on an old car just isn't worth it even though it doubles the range of the same amount of fuel (cost wise) and you get to keep a V8.
On an older Impreza it certainly wouldn't make financial sense unless you were to do mega miles.
You could probably engineer a tank in the place of the existing petrol tank but unless you can diy then more money. You'd still need a petrol tank but you colujld get away with a much smaller one. My rangie has a 40 litre petrol tank now - doesn't go very far on petrol!
Buy a turbodiesel something - probably a better idea.

Mapped a few cars with them installed, the main issue I see with them is the flash lube is not injected. Just sucked into the inlet manifold, therefore all the time the manifold is in positive pressure you have no flash lube entering the engine. Not ideal on a turbo engine.
Couple of traders I have done work for have had cars in for rebuilds with resessed valve seats running on lpg.
Usually foresters and legacys.
I think if you have it do so it switches off at very low boost say over 0.2 bar its off and manual switch to turn it on then you can turn it on when cruising on the motorway it should be fine but see other posts for other negatives.
Just buy a diesel golf for daily and make the impreza weekend/evening toy.
I did look into it a little more and found no local stations selling lpg.

This. Or just drive it carefully, I've managed 34 mpg over a week so its not impossible to get decent figures from them.I did look into it a little more and found no local stations selling lpg.
