I just went to check this out.  I took some EFI parts and relays, but otherwise it's driveline is complete.  Mileage unknown, interior is in pieces.  F54/P79 that was allegedly running for some time in the recent past.   5 speed/driveshaft/rear diff are all there.  Sounded more like vacuum leaks/EFI problems than bad rings as mentioned in his post.  He seemed like a decent dude(early 20's) with a desire to mess with Z's, just ended up with a basket case.

He's only going to get about $50-100 from a wrecking yard.  The engine trans and diff would probably be worth picking up as a set.  It only takes one of them to be good and the buyer is probably paid back.  Buy those and let him scrap the rest.  Even a set of good injectors, a fuel rail, and an FPR might make it worthwhile.  A garage full of spare parts gives comfort.

Thanks for the heads up @Zed Head. I really only care for the transmissions from the ZX. Not much else. Probably would be a good deal for this one.
