anyways,
http://www.sportcompactcarweb....urbo/if you scroll down there are some year to year changes that i thought were neat. 1996 models had a little less power. look for replaced turbos around 80-120k miles, they are expensive to replace. clutches around there. and like evildky said timing belt. check tire condition for driving habbits.
good luck, the car is incredible but it's a money pit.
oh, and i wanna say the later ones had bigger/lighter brakes....not sure about that though.
Turbo's don't really need to be replaced that often. I know of quite a few Z32's with 150K+ that have zero turbo problems. All depends on how bad the car has been abused.
Also, as for the brakes. Only the very early 1990 NA's (one's manufactured in late 1989) had the smaller 26mm brakes versus the later 30mm brakes. Every TT had 30mm brakes and all but the earliest NA's did as well. The only other braking difference was that Nissan originally used Aluminum calipers to save weight but later on switched to heavier steel ones.
Anyway, like everybody said, check to see that maintence has been done, run a carfax on it, get all the history you can about it, check tire wear for bad camber (upper arms, tension rods, and other parts are common to wear). Other than that stuff, if they were properly cared for, Z32's are very durable cars. Good luck on your search and make sure you ask lots of questions!
