Answer Belt.........
The alternator belt on a 1993 Nissan 300ZX will typically squeal if it has excessive wear or it has become lose. This provides a good opportunity to replace the belt before it complete fails.
The belt is a PK3 & its 925mm long.
About 1100 (Nissan dealer quote) that's water pump timing belt and th rest of the parts you need, I'm sure you could find it a little cheaper .

This is not a hard job, but will take some time to do. You will need an impact wrench and a gear / pulley puller; do not even attempt this job with out these tools
The 1990 Stanza has a chain.
how to change a timming belt on a 1986 Nissan pickup v6
You may have a serpentine belt on that car. I believe they had an electric fan. The serpentine belt is black and you can see it by your alternator, A/C compressor, etc. Under the hood of your car should be sticker on how to route the belt. You can look at that sticker and then see where your belt goes. There is no fan belt on a 1991 Nissan 300zx. The fan is directly driven by an electric motor. The water pump, alternator, and air conditioning compressor are belt driven. The belt for those components is located at the front of the engine.
