I WOULD like to convert my 2004 Subaru Outback 2.5-litre four-cylinder to LPG. I've been advised to go for a conventional system or an injection system, but the latter costs relatively more than a conventional system. Does my vehicle need to have the direct injection system? What are the differences?
THERE is no functional reason your car must have the injection system, though it is much better for performance and general driveability. Systems for cars built after 2003 must pass an emissions test, which adds to the development cost of the system, and LPG system manufacturers haven't necessarily invested in the development of the older system. You might simply not be able to find an older system for your car.
