Change of Engine
1. Replacement engine is identical to the original engine, or is an option allowed by the manufacturer for the same model vehicle
The optional engine must be offered in Australia by the vehicle manufacturer as an option for that vehicle (or certified variants). The change of engine may be recorded by VicRoads provided that the registered operator or a motor mechanic, or dealer in that make of vehicle or an Automotive Engineer signs a declaration certifying the engine is optional for the vehicle model, and that all modifications made by the manufacturer for the same vehicle model with that optional engine, have been completed.
