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 & Track magazine 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.
The 100NX came with two engine options, a 1.6L and a 2.0L.
The 1.6liter, made from 1990 to February 1993 had a carburetor fitted which tended to consume excessive fuel as it aged. From April 1993 onwards, the 100NX was sold with a more efficient fuel injected setup.
- 1.6 carbureted — 90bhp (67kW; 91PS)
- 1.6 fuel injected — 105bhp (78kW; 106PS)
- 2.0 fuel injected — 150bhp (112kW; 152PS)
- 2.0 fuel injected — 140bhp (104kW; 142PS) North American version
The 1.6liter fuel injected version achieved 0–60mph (0–97km/h) in 10.5 seconds and had a top speed of 121mph (195km/h).
The 100NX was mainly sold with a T-bar removable roof in Europe.
NX Coupe (Japan)
The Nissan NX was also sold in the Japanese domestic market as the Nissan NX Coupe. Some models were fitted with T-Tops, whilst others were hardtop. The Japanese domestic NX Coupe's came with either a 1.5 DOHC carburetted engine (GA15(DS)), a 1.6 DOHC EFI engine (GA16(DE)), a 1.8 DOHC EFI engine (SR18(DE)) or the rare 2.0 DOHC EFI engine (SR20DE). The model was available in automatic or manual transmission. The 1.5 DOHC models were all fitted with digital speedometers, whilst all other engine versions had the standard analogue gage. All Japanese domestic models were fitted with electric windows, air conditioning, power steering, electric mirrors and central locking which locked the doors automatically at 18 km/h whilst driving.
