In 1989 Nissan replaced the Z31 chassis with the Z32. Production of the naturally aspirated versions began in the Spring, followed by the twin-turbo in the Fall. The new VG30DE engine code reflected the use of Dual overhead cam heads. The twin-turbo model had the VG30DETT (Twin-Turbo) engine.

The twin-turbo 2+2 (four seat model) was never sold in the United States. Buyers in the U.S. who desired a four seat twin-turbo either had to legally import the foreign model, or convert a domestic NA 2+2 model to use a twin-turbo engine. The conversion process can be performed by mechanics familiar with the Z32. The conversion entails switching many parts in the engine bay to the twin-turbo versions as well as making some slight engine bay alterations to fit certain parts such as the radiator.

It was the first Japanese car to be sold following the introduction of a 280-PS power ceiling imposed by JAMA.

Nissan manufactured two special Z31 models. The 1984 300ZX 50th Anniversary Edition, released to celebrate Nissan’s half-century, was a fully-loaded turbocharged model with a Silver/Black color scheme. All 50th Anniversary Edition came equipped with a digital dash including MPG and compass readouts, in-car electronic adjustable shocks, Bodysonic speakers in the seats, cruise and radio controls in the steering wheel, mirrored t-tops, embroidered leather seats, embroidered floor mats, sixteen-inch (406 mm) aluminum wheels, rear fender flares, different front fenders, and 50th AE logo badges on the body. The only option available to the 50th Anniversary Edition was the choice between an automatic or a 5-speed manual transmission. Notably, 1984 also marks the last year of turbochargers cooled entirely by oil. 1985 turbo models are equipped with coolant passages to ensure turbo longevity. In 1988, the turbocharged Shiro Special debuted with pearl white paint, stiffer springs and matched shocks, heavy-duty anti-sway bars, a unique front air dam, paint matched wheels, Recaro seats with matching door panels, painted bumperettes, white painted doorhandles and a viscous, limited-slip differential. No other options were available for the Shiro, meaning all Shiros were identical. It was the fastest car out of Japan, capable of 153 mph (246 km/h) speeds, as tested by Motor Trend with the electronic speed limiter disabled. A total of 1002 Shiro Special Z31s were produced for the US market between January and March 1988.
