Today I became an owner of a 1989 300zx here in Japan. So I'm guessing the 1989 is equivalent to 1990 US spec. The car is high mileage around 100k miles. I've read the FAQ and the first thing that will get looked at is the water pump and timing belt. While I'm at the shop what else is recommended to get replaced/looked at with this mileage. Thanks for this great forum!
