HOLDEN COMMODORE V8 5.0LTR EFI
V6 Conversions offer conversion kits to allow the fitting of Commodore V8 EFI engines
to petrol or diesel vehicles. You can use the standard 5 speed 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 emission
components 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.
The kit is designed to allow the use of airconditioning and power steering, you use the
Commodore power steering pump and the Commodore A/C pump and adapt the lines.
The transfer case can remain in its original position. You use the Commodore engine
mount rubbers with our weld on engine mount brackets.
The 5-Speed manual kit utilises the GM flywheel and clutch along with the Toyota
bellhousing. Instead of a new bellhousing, a flywheel housing is supplied which
measures 122 mm/4.8" long. This housing has the GM bolt pattern on the front and the
Toyota 1F, 2F, and 3F, bolt pattern on the rear. The kit has been designed to allow for
firewall clearance without shifting the transmission or altering the drive shaft lengths.
The gear box input shaft is coupled to the clutch via an input extension shaft. The shaft
has the Toyota internal spline and spigot diameter on the gearbox end with the GM
external spline and spigot diameter on the engine end. The front of the shaft is
supported in the crankshaft by a sealed ball bearing inside an adaptor ring. The clutch
is operated through a thrust bearing extension sleeve, which is supported in a machined
boss located in the centre of the housing. On the front of the sleeve is a bearing to suit
the GM clutch pressure plate.
You will need to obtain the following components -
* The Commodore V8 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, airconditioning compressor & power steering pump, engine pipes &
catalytic converter, external fuel pump & damper. The standard Commodore in tank,
fuel pump cannot be used. We recommend you use an external EFI Commodore V6/V8
pump (Ashdowns part no: 27-28753).
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.

hand parts will need to be purchased for the instillation. A bellhousing from a 2F or 3F
