V6 Conversions offer conversion kits to allow the fitting of Commodore V6 EFI engines and the Commodore 700R-4 or 4L60-E 4 speed automatic transmission to Navara and Pathfinder .


V6 Conversions have available transfer case adaptor kits to fit GM Turbo 700R-4 and 4L60-E automatic transmissions to transfer cases. The transfer case adaptor housing replaces the automatic transmission extension housing. The adaptor housing then fits to the transfer case using the original Nissan bolts.

The automatic transmission will need to be disassembled. The main output shaft is removed and replaced with one supplied in the adaptor kit. This output shaft has a new spline to connect to transfer case .There is some cutting and welding required in this conversion in the engine mount area.

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.

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 – VX 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 uses your original speedo cable for VN, VP auto’s and VN – VY manual’s or an electronic speedo for VR – VY auto instillations.
