V6 Conversions have developed a conversion kit to allow the fitting of the Commodore V6 EFI engine and T700 auto or T5 manual gearbox, from VN through to VY to the Bedford.

To comply with Australian emission laws the engine must have been manufactured the same year or later than the vehicle. The engine must also have all of the emission components connected, including the catalytic converter. The engine must also be run on unleaded fuel or LPG.

In Australia an Engineers report is required after the conversion has been completed. Contact your local RTA office for a list of Engineers.


The kit is designed to use the original engine mount rubbers and with this conversion you can only have power steering or air conditioning, not both. With the gearbox mount being a bolt in using the VN gearbox rubber mount.

You will need to obtain the following components –

* The Commodore V6 engine complete with the main engine wiring harness, the ECM computer and memcal. Other accessories such as the map sensor, purge canister, air cleaner & ducting, air conditioning compressor & power steering pump, engine pipes & catalytic converter, external fuel pump & damper.

The Series One engines have two crankshaft bolt patterns and starter motor types, the manual transmission type and the automatic transmission type. For this reason they are not interchangeable.

However, Series Two and later engines have the same crankshaft so they can be converted from automatic to manual by fitting a flywheel and changing the memcal. This only applies to VN and VP engines, VR and later engines have different computers and wiring looms for automatic and manual.

The standard Commodore in tank, fuel pump cannot be used. We recommend you use an external EFI Commodore V6/V8 pump ( Ashdowns part no: BFP070 ).The Commodore does not have an engine driven fan and the Commodore electric fan and shroud will not fit in the engine bay. An electric fan is required, we
recommend that you use a Davies Craig DC16 or similar.

The wiring kit we have available covers from the VN – VY. It comes in 2 parts, the under bonnet loom with all the relays and fuses and the under dash loom which incorporates an engine trouble light. The wiring kit plugs into the original engine and gearbox loom leaving only 6 wires to be tapped into your vehicles original loom, which are – alternator light, oil light, temp light or gauge, ignition, starter & tacho. Our speedo kit comes in 2 forms, an in line speed sensor that fits the T700 or T5 and your original cable to suit VN – VP, or an electronic speedo from VR – VY instillations.
