Holden Rodeo 2005: What brand is best for gas conversion?

HOLDEN offered a dual-fuel system for the RA Rodeo with the 3.5-litre V6 engine and that's the one I would recommend. It was developed by Impco and sold through Holden dealers. The warranty will be affected by modifications made to install the system. That means Holden won't cover the engine and other parts of the car that have been modified. You need to talk to the person installing the system to see what cover they provide for the equipment they supply and the work they do.
