As Above, has anyone ever known of an impreza that runs on lpg?

 

Never heard of one but I would think its a no no.
Engines running on LPG tend to run hotter than those that don't hence why you get valve seat erosion.

The problem with Turbos in general and Imprezas in particular is that generally they are over fuelled. The idea being that the excess fuel has a coolling effect on the engine. If you introduce LPG into the equation and thus make the engine run hotter you would probably run into problems.

Hope this helps.

 

i do know of someone on sxoc.com running a stage 1 (280 odd bhp) 200sx s14 running gas with no problems

 

i saw a Scoob (classic WRX) advertised a while back, said it was run on LPG. Looked into it, and it would cost £2k, and apparently if you drive 15K miles, it would take less than 2 years to recover the cost (not including new engine when old one goes pop!).

 

I have a leggy turbo running lpg and it has done for 2 years no problems occasional misfire 200 miles for £20 used daily oil always clean change plugs more often i do 500 miles a week

I don't understand all the people saying it will kill engines etc it can if not set up well but SO WILL PETROL

My car had 150k miles on it when i converted it it is at 178k now it could go pop tomorrow but then so could yours lol

 

Bear in mind too; that LPG has a RON of way over 100..........
