V6 Conversions offer conversion kits to allow the fitting of Commodore V6 EFI engines to Landcruiser petrol or diesel vehicles. You can use the standard 4 speed transmission or alternatively the Commodore 700R-4 or 4L60-E 4 speed automatic transmission. To comply with Australian emission laws the new engine must have been manufactured the same year or later than the vehicle. The engine must also have all of the emissioncomponents connected, including the catalytic converter. The engine must also be run on unleaded fuel or LPG.
In Australia an engineer’s report is required after the conversion has been completed. Contact your local RTA office for a list of engineers.

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

The wiring kit we have available covers from the VN – VT. 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 or an electronic speedo from VR – VT instillations.
