Berlina lpg conversion

TO BEGIN with, the general experience with the Alloytec V6 is it doesn't handle LPG well without the hardened valves and valve seats Holden installs in its LPG-compatible engines. LPG industry insiders tell me they are seeing head rebuilds at 30,000km, which really means the conversion isn't economically viable. There will be installers who will disagree with me, but ask them to give you the evidence the VZ V6 is OK on gas. The best system is the injection system, but it is more expensive than the old valve/mixer systems. There is little difference in output when running on LPG with the injection system, so there is no loss of performance.
