Too old?

Too old?
Well tommorow me and my pops are going to check out a 90' 300ZX TT. It has 156K miles. Everything is original except for the exhuast. I'm not really sure if the turbos were rebuilt or replaced. How would i know if the turbos are seized? Is there a noticeable loss in power? Overall the car is in great condition. The turbos concern me because i read somewhere here that they usually seize up at like 120k.

I believe, a good sign that the turbos are going bad will be exhaust smoke. As they wear, the shafts will eventually get loose in the bearings which will wear out the oil seals causing the oil leak. I wouldn't run worn turbos too long because they are rebuildable, that is until they get so worn that the turbines inside start to hit the housings, which destroys them.

i'm glad i didn't see any exhaust smoke on idle. can't remember if i saw any while driving. oh well if we get i'l make sure i check it out. and for the turbos im thinking about getting the new stock turbos on z1motorsports.
