The NX1600 was based on the standard 1.6L Sentra (engine code GA16DE), and the NX2000 was based on the 2.0 L SE-R model (engine code SR20DE). Most models were fitted with T-Tops, whilst others were hardtop. Constructed in Japan, was sold from 1991-1993 in the US (mainly competing with the Mazda MX-3, Isuzu Piazza and Honda Civic Del Sol). Also, it was produced for a few more years and sold in other countries.
The NX2000 model had some mechanical improvements over its SE-R sibling. It had larger brakes and more aggressive tires on wider 6" wheels (195/55VR-14 with 14x6" wheels vs. the 185/60HR-14 with 14x5.5" wheels and tires in the SE-R). The NX2000 brakes are a common aftermarket upgrade for B13 Sentra SE-Rs. The NX2000 also had a center armrest, a larger two core radiator, and slightly lower ride height compared to the SE-R. However, the T-top roof in the NX2000 along with the mechanical upgrades made it slightly heavier than the SE-R.
The NX2000, with its light weight, stiff chassis, and limited-slip differential, was considered one of the best-handling front-wheel-drive cars of the time. In 1992, Road & Trackmagazine included the NX2000 in a test of the world's best handling cars against such competition as the Acura NSX, Porsche 911, Nissan 300ZX, Mazda Miata, and Lotus Elan.
