HQ – HJ – HX – HZ – WB.

V6 Conversions have developed a conversion kit that allows the instillation of the Holden Commodore V6 3.8ltr EFI to the above vehicles from VN to VY the kit is designed to replace the original 6 cylinder or V8 motor & gearbox. The kit is designed to take the T700 or T5 gearbox.

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

CONVERSION INFORMATION.

This is a very simple conversion with all components being an all bolt insuitable for all body styles including HQ, HJ, HX, HZ & WB sedans, wagons, utes, tunners, vans & Monaro’s.

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.

You can leave your original fuel tank in place by using an external EFI fuel pump and modifying the filler neck by way of a return line and restrictor so that it will only accept an UNLEADED nozzle or you can fit a complete fuel tank from the VN Commodore.

The V6 motor does not have an engine driven fan, you can use your original radiator and fit the fan and cowling from the VN-VT or a 16″ Davies Craig 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 V6 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 cable to suit VN – VP, or an electronic speedo for VR-VY instillations.
