Mine's 87 and its carby! VG30DETT isn't the only variant of the turbo V6, i'm looking for the VG30ET motor from the first 300ZX, the Z31. Its single cam, single turbo, same era as the D21's, a very narrow engine from strut to strut compared to the twin turbo with no need to cut up the internal guards. I've been doing some looking and all you need to keep the Pathy 4WD is to have the manual bellhousing and gear retaining plate off the 300ZX and it bolts straight up to the Pathy V6's gearbox! They're just hard to find for cheap, at least in Australia, don't know about America.
