The Nissan 300ZX, also known as the Nissan Fairlady Z is a sports car produced by Nissan Motor Company. It comprises the third and fourth generations of Nissan's Z-car line-up, respectively given the chassis designations Z31 and Z32.

The Z31 chassis designation was first introduced in 1983 as a 1984 model and the third-generation Datsun/Nissan Z-car. The car was designated as a Datsun/Nissan 300ZX in its 1984 premiere, but the Datsun badge was dropped in 1985 when Nissan standardised their brand name worldwide. The car was designed by Kazumasu Takagi and his team of developers, and featured a new, more aerodynamic body than its 280ZX predecessor. It also had a more powerful line-up of V6 engines instead of the old I6 used in the 280ZX. According to Nissan, "the V6 engine was supposed to re-create the spirit of the original Fairlady Z." (Datsun 280 Nissan 300ZX, p.65) This new V6 (2960 cc) SOHC engine was available as a naturally-aspirated VG30E or a turbocharged VG30ET producing 160 and 200 horsepower respectively. The VG30E(T) engine was either a type A or type B sub-designation from 1984- 4/1987: models from 5/87-1989 had a W-subdesignation. The W series featured redesigned water jackets for additional cooling, as well as fully floating piston wrist pins. W motors were rated at 165 (non turbo) and 205 (turbo) horsepower. 1984-1987 turbo models featured a Garrett T3 turbocharger with a 7.8:1 compression motor, whereas 1988-1989 models featured a low inertia T25 turbocharger, and increased compression (8.3:1) to produce the 5 extra horsepower. Finally, these motors were equipped self-adjusting hydraulic valve lifters.
Chassis
The chassis remained somewhat similar to the 280ZX, with the same 91.3 in (2319 mm) wheelbase and MacPherson strut/trailing arm independent suspension, however the 300ZX both handled and accelerated better than the 280ZX it replaced. All turbo charged models (except for the SS special edition) featured 3-way electronically adjustable shock absorbers.
Style and evolution
Due to its quickly aging design, the Z31 body was slightly restyled in 1986 with the addition of side skirts, and removal of the hood scoop for a much smoother look. The old rubber spoiler was replaced with a more durable fiberglass one, and a third brake-light was incorporated within the unit for safety. The car was given a final makeover in 1987 that included more aerodynamic bumpers, fog lamps within the front air dam, and replacement of the sealed beam style headlights with more modern 9004 bulb based lights. The "300ZX" reflector in the rear was replaced by a narrow set of tail lights running the entire width of the car, and a l.e.d. 3rd brake-light located on the top of the rear hatch. The car continued selling until 1989 and sold more than any other Z car made to date with over 70,000 units sold in 1985 alone. In 1990, Nissan replaced this very successful car with the Z32, and was a complete redesign version of the Z31. It was also titled the 300ZX because it retained a 3-litre engine.
Z31 popularity
Although the Z31 is an aging vehicle, it remains very popular among fans and enthusiasts. People are now realizing how much of a "Bang for your buck" the Z31 really is.

The Z32 was a significant redesign over the previous Z31. It featured a naturally aspirated engine rated at 222 hp, and a Twin-Turbo version rated at 300 hp (224 kW) and 283 ft. lbs. of torque at 9.5 psi (66 kPa) of boost through two parallel intercoolers. Beginning in 1991, a hard-top model ("slicktop") was introduced (comprising 17% of production models from 1993-1996 [1]), offering slight weight reduction and increased structural rigidity over the t-top models. A naturally aspirated convertible model was also introduced in 1993. While the Twin Turbo was only available as a coupe in the United States, it was available as a "slicktop", 2+2 and Coupe in Japanese Domestic Market.
The twin-turbo Z32s can be spotted with a different front bumper featuring three vents for supplying air to the dual intercoolers, as opposed to the naturally aspirated (NA) models. They also came with the requisite "Twin Turbo" badging in the rear and a subtle tail spoiler, which was enlarged and redesigned in 1994. The turbo model also featured larger 245/45-16 and 16x8.5 wheels in the back as opposed to the 225/50-16 tires in front and on the NA version.
One major difference between the VG30E(T) in the Z31 and the VG30DE(TT) placed in the Z32 was the dual overhead cam design and variable valve timing system.
The platform was new, with a longer 97-in wheelbase and sophisticated multi-link suspension front and rear. Twin Turbo models featured electronically adjustable shock absorbers, and Nissan's all-wheel-steering system SUPER HICAS (Super High Capacity Actively Controlled Suspension), which could turn the rear wheels a full two degrees at speed.
The Z32 TT was discontinued in the UK in 1994 after failing DOT emissions, and in 1996 in much of North America due to dwindling sales figures, and rising production costs. The price of a Twin Turbo 300ZX rose to US $45,000 that year, too high for many consumers and far from the US $27,000 price it had started with. Production of the Z32 continued in some American states and Australia through a major redesign in 1998, in naturally aspirated 2-seater, 2+2 seater, and "R" versions, which were 2+2 twin turbo models.

Awards
The Z32 300ZX Turbo was on Car and Driver magazine's annual Ten Best list every year it was available, from 1990 through 1996. The Z32 Turbo was also Motor Trend's Import Car of the Year for 1990. It was critically acclaimed by many magazines as being a complete turnaround from the Z31, which many critics felt was a sloppy-handling GT, far from the agile, sporty 240Z of years past. From the year it was introduced, it won many comparison tests against similar sports cars such as the Mitsubishi 3000GT/Dodge Stealth and the Mazda RX-7, as well as the Chevrolet Corvette, Toyota Supra and the Porsche 968.
The Z32 300ZX also made it to Automobile Magazine's list of 25 Most Beautiful Cars in August 2006.
Safety
In Australia, the 1990-95 Nissan 300ZX/Fairlady Z was assessed in the Used Car Safety Ratings 2006 as providing "average" protection for its occupants in the event of a crash.
Racing
In 1984 to 1985 showroom stock racing, the 300ZX (Z31) was a potent competitor and captured wins on numerous occasions. The car scored its only Trans Am win in 1986 at Lime Rock by Paul Newman for Bob Sharp Racing
From 1985 to 1987, the Electramotive-developed GTP ZX-Turbo was raced in the IMSA GTP class and also the All Japan Sports Prototype Championship, badged as a Fairlady Z, using a Lola T810 Chassis and a VG30ET engine. A series of crashes attributed to tire blowouts combined with difficulty of working on the T810 chassis caused less than stellar performance both seasons.
Later on between 1988 and 1989, the Nissan GTP ZX-Turbo dominated in IMSA GTP racing. Additional factory endorsement, combined with a new chassis, gearbox and more reliable Goodyear tires contributed to the team's success. The new Electramotive (later to become NPTI) chassis was easier to work on, more robust and technically superior to the T810. The VG30ET was making upwards of 800 hp, with a power band that extended from 4000 to 9000 rpm.
From 1990 to 1995, as well as dominating the GTP category, now with a newly designed chassis, the 300ZX (Z32), who was campaigned by Clayton Cunningham Racing was championed by Steve Millen in the International Motor Sports Association (IMSA) and its GT and GTS classes. He was ranked as the #1 Factory Driver for Nissan for 7 years, as well as two IMSA GTS Driving Championships and two IMSA GTS Manufacturer's Championships before the car became banished from competition altogether.
The Z32 also holds a land speed record in the E/BMS class. A joint effort between Jun Auto and Blitz Motorsport was able to produce a 300ZX that reached 419.84 km/h (260.932 mp/h) at the Bonneville Speedway. This record remains unbroken.
