For the 1996 model year in the US, the turbo model was only available with the automatic transmission owing to OBD-II certification requirements. The targa roof was also made standard on all turbo models. For 1997, manual transmission returned for the optional engine along with a redesign of the tail lights, headlights, front fascia, polished wheels, and other minor changes such as the radio and steering wheel designs. All 1997 models included badges indicating "Limited Edition 15th Anniversary". All turbo models came standard with the rear spoiler. For 1998, updates were a 3-spoke steering wheel, a redesigned radio, and VVT-i on the naturally aspirated engine. In Japan, the turbo engines were installed with VVT-i. The SZ-R model was also updated with the introduction of a six-speed Getrag V161 transmission, the same used for the twin-turbo RZ models.
