Has anyone looked into this ?

Will an Infiniti VK45DE variable intake manifold bolt onto a VK56DE, the electronics can be worked out after.

Will an Infiniti VK45DE crank pulley fit the VK56DE and what is the radius

ThanksTT

no it will not fit b/c the block is wider. this is due to the higher deck height on the 5.6l.

Hey Bio or anyone is this a fact meaning that it has been test fitted already to a VK56DE?

Anyone have a VK45DE intake sitting around?

The runner and plenum volumes must be matched to the displacement inorder to function tune correctly............everything will be 25% too small for 5.6 even if it could be made to fit.
