In 1990, for the 1991 model year, the SR20DE and SR20DET engines debuted in the S13 Silvia, offering improvements across the board in power, torque, and efficiency over the CA18DE(T). The S13 Silvia was discontinued after the 1993 model year, in favor of the new S14 chassis design. The S14 Silvia debuted in Japan at the end of 1993. Wheelbase and track were both increased slightly, leading to slightly improved handling. The S14 Silvia K’s received a new “notchtop” version of the SR20DET, boasting a slight bump in power due to the implementation of Nissan’s variable cam timing system, VTC, and a more efficient ball bearing turbocharger. Japan saw a new version of the Silvia (S15) in 1999, now boasting 250 hp (164 kW) from its SR20DET engine thanks to a slight turbocharger upgrade, as well as improved engine management. The SR20DE (non-turbo motor) featured only 165 hp.
