Can anyone give me advise on converting my VT SS sedan to LPG?
I have 1998 VT SS 5 litre V8 which I converted to gas about 2.5 years ago. Best thing I ever did. I got the vapour injection system which set me back $4400. Basically the same power as petrol and I get 410-430 per tank out of 73 usable litres. I have done just over 80,000klms since the converstion with no problems at all. If you do convert to gas also get your rear springs changed to standard height heavy duty to allow for the weight of the tank, as I didn't do this and it chewed through near new tyres in 20,000klms. After I had the springs changed no problem at all, these tyres have now done 60,000klms. Hope this helps.
If I were to do it I would go the liquid injection system.
