he S14 Silvia debuted in Japan towards the end of 1993. It was lower and wider than the S13. New rounded styling contributed to the illusion of a greater increase in size than actually occurred. Wheelbase and track were both increased, leading to slightly improved handling. Unlike export markets, where sales of the S14 chassis variants faltered, the Silvia remained popular in Japan. However, the width dimension exceeded 1,700 mm (67 in), which pushed this generation out of the compact class tax bracket and made Japanese buyers liable for higher road taxes. Sales of the S14 also faltered because specialty car buyers at the time were moving to RVs and SUVs. The fastback and convertible bodystyles were discontinued internationally, leaving only the coupé in production.
Trim level designations were similar to the S13, however the Club Selection package was dropped. “Aero” variants of the Q’s and K’s were offered that featured large rear wings and mild ground effects.
The S14 Silvia K’s received a new version of the SR20DET, with a slight bump in power due to the implementation of Nissan’s variable cam timing system known as N-VCT, on the intake cam, and a larger T28 turbocharger.
There was a mild styling update to the S14 during 1996, which added aggressive-looking projector headlamps and tinted taillights to all models. Fascias and other exterior trim pieces were also revised. The turbocharger now used a more efficient ball bearing center section. This updated version is also known as the kouki (後期, literally “later period”) S14, or by enthusiasts as the S14A. It was sold as the second generation 240SX in North America from 1995 to 1998, equipped with the non-turbo KA24DE engine. The final model year of S14 production in all markets was 1999, called the Touring Model, which had a better engine block, pistons, and better acceleration in lower gears.
