COMMODORE V6 3.8LTR EFI
HILUX 4X4 / 4 RUNNER.
V6 Conversions offer conversion kits to allow the fitting of Commodore V6 EFI engines to Hilux 4WD petrol or diesel vehicles. You can use the standard 5 speed transmission or alternatively the Commodore 700R-4 or 4L60-E 4 speed automatic transmission.
The Commodore V6 engine can be adapted to the Hilux 4WD petrol or diesel. Using 5 speed gearbox. The bell housing has been designed to space the engine away from the firewall in order to clear the V6 throttle body located at the rear of the intake manifold. There are no firewall modifications, re positioning of the transmission or drive shaft modifications required.
The clutch is coupled to the gearbox by a special gearbox input extension shaft. It has the GM spigot diameter with external spline on the engine end and Toyota spigot diameter with internal spline on the gearbox end.
The bell housing allows the standard V6 GM clutch pressure plate with a V8 clutch disc to be used on the V6 flywheel. The V8 clutch disc provides less clutch shudder due to the clutch plate having stronger centre springs.
The Hilux diesel 4 cylinder slave cylinder must be used. It will need to be re-sleeved to 11/16″ bore. This is required to give sufficient throw for correct clutch operation.
AUTOMATIC TRANSMISSION TO TRANSFER CASE.
V6 Conversions have available transfer case adaptor kits to fit GM Turbo 700R-4 and 4L60-E automatic transmissions to Hilux 4WD gear driven transfer cases & chain driven 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 Toyota bolts. The housing has mounting provision for the Hilux 4WD hi-low lever.
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 the Hilux 4WD coupling sleeve found on the main shaft of the 4 or 5 speed gearbox.
The left hand chassis mounting uses the standard GM engine bracket and mounting rubber. This design allows the use of the standard GM air-conditioning compressor if required. The new bracket is welded to the chassis.
The right engine mounting bracket bolts to the Commodore V6 engine block and fits to the Hilux 4WD diesel 4 cylinder mounting rubber and chassis post.
The 3 core diesel radiator is large enough to keep the Commodore engine cool. The 2 row petrol radiator is too small and must be replaced.
The Commodore engine does not have an engine driven cooling fan, an electric fan must be used for the conversion.
Commodore VR, VS, VT and VY engine management computers require a stream of data to be sent to them from the body control module prior to starting the engine. This is part of the vehicles anti-theft system, unfortunately the system can not be used in the 4WD application. The stream of data required by the ECM is a special one off code, this makes it very hard to duplicate. Fortunately the input to the ECM can be switched off by changing the program information in the memcal. V6 Conversions can supply memcals on an exchange basis.
TACHO INTERFACE KIT.
The tachometer interface will make operative the diesel 4 cylinder tachometer by converting the pulses received from the V6 DFI module.
