Hi I have a Kluger and also a BA XR6T that is running a LPG injection system that pulls nicely around 320 KW and has done for around half a million kms now with absolutely no problems. In fact I believe the Ford 4 liter turbo will go a lot further as LPG injection will keep the engine/oil clean from carbon deposits, provide better lubrication at the absolute cylinder wall as any unburnt gas will not attack the cylinder lubrication oil film like petrol. Another big advantage of LPG with a turbo is that it burns hotter to spool up better, is 110 plus octane that is great for extra boost reliability without knocking and will act as a secondary inter-cooler upon injection as the gas cools the inlet charge. This has worked really well as the Ford 6 was fully factory designed to run on LPG from the factory with Stellite exhaust valves/seats setup for the extra heat but that is a big question for the Kluger and needs to be ascertained first as mentioned in other post.
