Holden Rodeo 2006: LPG conversion?

THE Rodeo's V6 is the same Alloytec V6 that's used in the current Commodore. Holden offers a dual-fuel kit for the Alloytec V6 in the Commodore, but it has been modified for running LPG. Holden had been working on a similar installation for the Rodeo, but backed away from it because of difficulties having the LPG-compatible engine fitted in the Thailand plant where the Rodeo is built. It also checked to see if it could get away with running the standard V6 on LPG, but found problems quickly developed with the cylinder heads so never went ahead with the release of the kit. That was an injection kit being developed for Holden by Impco. Impco's advice at that time was that the Rodeo V6 was not suitable for gas, but the guys at the Australian LPG Warehouse have developed kits for it and claim they have fitted them to Rodeos and Commodores and have had no problems. The secret, they say, is they make sure the engine runs rich enough at wide open throttle on LPG so the combustion temperatures don't get high enough to cause problems with the valves and head.
