The Nissan 180SX is a fastback automobile that was produced by Nissan Motors between 1988 and 1998. It is based on the S13 chassis from the Nissan S platform with the variants receiving an R designation (ex. PS13 and RPS13), and was sold exclusively in Japan paired with the CA18 motor in the early models; later models paired with the SR20 motor. Outside of Japan, it was re-badged as the 200SX and in the US market as the Nissan 240SX, paired with the single overhead cam KA24E motor and later with the dual-overhead model KA24DE. Model nomenclature and markets The 180SX was built and sold by Nissan as a sister model to the Nissan Silvia from model year 1989 through 1998, but sold at two different Japanese Nissan dealerships. The Silvia was sold at Nissan Prince Store, and the 180SX was sold at Nissan Bluebird Store locations. In Japan, the 180SX replaced the Gazelle. The S13 Silvia was discontinued in 1993, but the 180SX was successful enough to convince Nissan to keep it in the market for the full length of the next generation Silvia (S14). The 180SX differed from the S13 Silvia in that it featured pop-up headlights and a liftgate with different body work at the rear of the vehicle. Specifications and equipment were similar; however, the naturally aspirated CA18DE engine was not offered. The name 180SX was originally in reference to the 1.8 liter displacement CA18DET engine used in the chassis. In 1991, however, the engine was upgraded to a 2.0 liter model, offered in two forms: the turbocharged SR20DET variant and the naturally aspirated SR20DE engine, which was introduced in 1996. Although the new engine was of larger displacement, the 180SX nomenclature remained. 180SX was also a trim level of the S110 Silvia in Europe. The badges for this model read "Silvia 180SX", so this car is not properly a 180SX by model, but a version of the Silvia instead. Other discrepancies from this standard were distributed to Micronesia and South Pacific islands, including LHD cars with 180SX badges and non-retractable headlamps. Like the Japanese 180SX SR20DET discrepancy, European, as well as South African models of the S13 chassis were called 200SX though equipped with the CA18DET engine. In North America, It was sold as the Nissan 240SX Fastback with the KA24DE engine and various other trim differences. In Europe the car was sold as the
