According to Motor Trend, the US sales figures for the last-generation 300ZX were as follows:
The 300ZX is a very quick car. The non turbo models turn in a 0-60 time around 7.5 seconds. The turbo models turn in 0-60 times closer to 5.7-6.2 seconds. Of course, these are rough figures. Any 0-60 estimates can be off by as much as 20%, depending on the driver, road and weather conditions, etc. The twin turbos are fast. Generally speaking, they hold their own with most major manufacturer's flagship sportscars. (IE the Mitsubishi 3000GT, Toyota Supra, etc)
What are all these acronyms I keep hearing?
90+ - Built between 1990-1996 (current body style) TT - Twin Turbo NA - Naturally Aspirated (non-turbo) 2+2 - 4 seater version (but the rear seats are nearly useless) HICAS - High Capacity Actively Controlled Suspension (ie 4 wheel steering, TT only)
How can I identify turbos vs non turbos?
There are a few dead giveaways in the Turbo vs Non-Turbo question. First, all turbo cars come from the factory with a vented front air dam, and a rear wing. The "twin turbo" sticker on the right side of the hatch, and the bat-out-of-hell acceleration are also good to look for. However, if you're convinced the car you're looking at could be an imposter, look at the speedometer. The bottom sixth of the speedo gauge houses the Boost Pressure indicator, with a scale from -14 to +14 psi. If this is missing, no way it's a turbo. Another good indicator is the tire size - Twin Turbos were outfitted with 225s in the front, and 245s in the rear. Non-Turbos wore 225s all around. If you look carefully at the rear wheels of a Twin Turbo, you'll notice that they have more of a "dish" to them, whereas the front wheels are relatively flat.
How do I identify different model years?
There are a few hints as to the model year as well. For instance, 1990 cars did not have the centered "nissan hamburger" logo on the hood - this was added in 91. In 92, the interior fabric went from a woven carpet to a suede. There aren't many distinguishing characteristics between 92-96 model years. In 95 the turbo model no longer sported the "duck tail" spoiler, instead a redesigned, slightly taller wing was introduced.
