Hi all , to all you guru's i am putting a 308 into a 6 cylinder vk commodore do i need to get a new gearbox and diff or are they compatable it is a automatic calais 85 model
You need to change the transmission and diff to either a turbo vl or 10 bolt salisbury. Something stronger. Rear disc brakes would be advised too as well as a brake booster upgrade.
id even go so far as to change the springs and shocks to v8 items to suit the extra weight of the v8 block... but thats just being particular not much of the six cylinder stuff will last under the stress of a V8
Being a Calais it should already have a disc rear end. You'll need a different box to suit the 308, but the diff u could prolly get away with for a while.
Im about to undertake the same project with a VK royale but its the EFI model..Anyone know where i can get wiring diagrams from?Is there a seperate engine wiring loom like in the VHs that you can just unplug from body loom or is it all one loom?
If anyone can give me the full run down on the conversion from a six to a v8 in a vk commodore im new to this so any tips would be extremely helpful and appreciated
