Im wondering about LPG injection. I want to put a 5 litre injected into my XW, and id like to put it onto straight gas. Because LPG has higher octane, id raise the compression abit to yeild more power. But how is LPG injection done? Cheers

it needs a sequential petrol injection motor to work well

Can you just use a gas mixer, and push the vapourised gas into the fuel rails/injectors, or wont it work??
