V6 Conversions have developed a conversion kit that allows the instillation of the Holden Commodore V6 3.8ltr EFI to the above vehicles. The kit is designed to replace the original grey/red motor & gearbox. The kit is designed to take the T700 or T5 gearbox. There is some cutting and welding required in the gearbox tunnel area. The instillation is carried out with the use of a HR cross member.


We use a remanufactured rear mounted rack & pinion from a VB-VK Commodore which comes in our kit complete from tie rod end to tie rod end with all mounting brackets & bolts and instructions. With this steering kit you can use HR disc brakes or HQ-WB stub axles and brakes or we can offer you a stub axle that will accept VN-VP brake assembly.

The steering column used is up to the individual, in our instruction sheet we give you the measurements to convert the column or we have an exchange unit available.


It is up to the individual on which diff combination to run. However, we can convert you own VN-VS diff to suit.


We have covered part of the brakes in the steering, we have found the best combination is to use a brake booster from a VB-VK Commodore mounted to the firewall (the mounting bracket is supplied in our kit). You can either use the VB master cylinder or a VN master cylinder. This combination can be used with HR discs and drum or HQ-WB or VN-VP.


In our conversion kit we supply a set of extractors to clear the inner guards and firewall. We recommend that you run the catalytic converter and a 2 1/2” system and a full flow turbo muffler.


When fitting the T700, the tunnel only requires slight modification with a small amount removed from the tunnel support. When fitting the T5 the tunnel requires major modification.


The wiring kit we have available covers from VN-VY, it comes in 2 parts, the under bonnet loom with all relays and fuses and the under dash loom which incorporates an engine trouble light. This wiring kit plugs into the original 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, ignition, starter & taco.


Our speedo kit comes in 2 forms, an inline speed sensor and cable to suit VN-VP or an electronic speedo for VR-VS instillation.


It is best to use the original radiator, it is advisable to have the radiator serviced and run an overflow tank and recovery cap. With this conversion you can use a 16” thermo fan or fan assembly from a VR-VS Commodore, which is mounted behind the radiator and plugs into our wiring loom.


In our conversion kit we supply you with a drilling template to mount an LC-LJ wiper motor assembly, you should use the wiper switch from the LC-LJ.


An Engineers report is required after the conversion has been completed, contact your local RTA office for a list of Engineers in your district.

Requirements for Engineering are that seat belts must be fitted plus a heater demister.
