In quoting 1/4 mile times, make sure to distinguish between magazine tests, and tests you see at the drag strip. Magazines have standard procedures that they use, including bone stock cars, full fuel tank, stock tires, recommended air pressures, all stock equipment in the car, professional drivers, etc. As a result, they are usually pretty consistent from one magazine to another, with differences rarely exceeding two tenths of a second. Occasionally there is an outlier data point that is a whole lot slower or quicker, but most of the figures are clustered around a certain number that represents a "consensus figure". They're also easy for anyone to verify, by checking the particular issue in which the test appeared.
When people go to the drag strip, they usually do things that can better those times - mods (often not disclosed or noted), mostly empty gas tanks, drag tires, lower air pressures than recommended (to increase the size of the contact patch), spare tire and other equipment removed from the car, widely varying driver skills, etc. Because of all these factors, times at the drag strip are highly variable, and differences of one or two seconds or more between tests of the SAME CAR MODEL are not uncommon. That's why I find such anecdotal reports to be not particularly useful when comparing one car against another.
Most magazine tests of the '91-94 3.0-liter five-speed NSX put it around 13.8 in the 1/4 mile, and the '97-05 3.2-liter six-speed NSX-T around 13.3 or so. The 3.2-liter six-speed NSX Coupe is even faster, but those are quite rare. And, as with most cars, you can find a test or two with figures that are lower than that, but those are the consensus numbers from the magazines.
The 350Z (Track Edition) was tested by Road & Track (March 2003) at 14.4 (99.7 mph), and by AutoWeek (Nov 12, 2002) at 14.32 (also 99.7 mph). Again, I'm sure you can find a test or two with quicker numbers, but those are the consensus magazine test figures.
