Nissan Skyline GT-R (R32)

The 1992 Nissan Skyline GT-R

#### Concept

After cancelling the Skyline GT-R in 1973, Nissan revived the GT-R again in 1989. At the time Nissan was competing in Group A Racing with the Skyline GTS-R. Nissan wanted to retire the GTS-R in favor of a more competitive vehicle. The new generation GT-R, **E-BNR32** chassis (commonly shortened to **R32**), was designed to dominate Group A racing.

Nissan Kohki (Nissan's power train engineering and manufacturing facility) originally tested a twin turbocharged 2350cc bored and stroked version of the RB25 engine. This set up produced 233 kW (313 hp) and used a RWD drivetrain. Under Group A regulations, a turbocharged engine must multiply its engine displacement by 1.7, putting the new Skyline in the 4000 cc class, and requiring the use of 10-inch-wide tyres. Knowing that they would be required to use 10-inch-wide tyres, Nissan decided to make the car all wheel drive. Nissan developed a special motorsport-oriented AWD system for this purpose called the ATTESA E-TS. Although this assisted with traction, it made the car 100 kg (220 lb) heavier; the added weight put the GT-R at a disadvantage to other cars in the 4000 cc class. Nissan then made the decision to increase the displacement to 2600 cc, and put the car in the 4500 cc class, with the car's weight near-equal to competing cars. The 4500 cc class also allowed for 11-inch-wide tires. New engine block and heads were then developed to better match the increased displacement. The result was a 600 horsepower car. Later REINIK (Racing & Rally Engineering Division Incorporated Nissan Kohi) produced Group A racing engines between 373–485 kW (500–650 hp) depending on track conditions.

#### Production

This new 2.6 L RB26DETT-powered all wheel drive concept was put into production as the R32 Nissan Skyline GT-R. The R32 developed 206 kW (276 hp) and 266 lb⋅ft (361 N⋅m) of torque, it had a curb weight of 1,430 kg (3,146 lbs). Nissan officially started its production run 21 August 1989, and began its Group A campaign in 1990.

The Skyline GT-R Nismo, identified by the model code suffix "RA", was introduced on 22 February 1990 and attracted a premium of ¥235,500 over the standard car. It existed to homologate a number of changes related to performance, aerodynamics, weight-saving and reliability for Group A racing. Those rules required a production run of 500 units, under the "Evolution" special regulations, but an additional 60 were produced and held by Nissan to turn into race cars, giving a total production of 560 units. Aerodynamic changes include: two additional ducts in the front bumper and removal of the protective honeycomb mesh to improve airflow to the intercooler, a bonnet lip spoiler to direct more air into the engine bay, deeper rear spats, and an additional boot lip spoiler to provide more downforce. The Nismo specification deletes ABS, which are not legal in Group A, and the rear wiper to save weight. The bonnet and front bumpers are aluminium rather than the standard steel, again to save weight. Overall the GT-R Nismo weighs 1400 kg compared to 1430 kg for the standard GT-R. Tyres are Bridgestone RE71 in 225/55R16 fitted to 16" alloys. Mechanically the GT-R Nismo uses the RB26 engine of the 'standard' GT-R but replaces the stock Garrett T03 turbos with larger T04B models, sacrificing the faster spool up of the ceramic turbo wheels for the enhanced reliability of steel wheels. The GT-R Nismo was only available in colour code KH2 "Gun Grey Metallic". Other minor, but noticeable, changes include a circular "Nismo" logo on the right-rear of the boot lip, lack of radio tuning controls on the dashboard console (since a radio was optional), and cross-drilled brake rotors. Nismo-branded options available included a 260 km/h speedo, 3" cat-back exhaust system, front suspension tower brace, sports shock absorbers, 17" alloy wheels, and a rear spoiler with built-in tail light.

The Skyline GT-R 'N1' model (identified by the model code suffix "ZN"), was introduced on 19 July 1991, and designed for home-market N1racing with a total of 245 units eventually produced (118 of these are 'N1', 64 are 'V·Spec N1', and 63 are 'V·Spec II N1' - see below explanation of 'V.spec'). The most notable change was in the engine, which was upgraded to the R32-N1 specification. Building on the 'Nismo' car's specification, it was also lightened by the removal of the ABS, and rear wiper, but for 'N1' the air conditioning, sound system, and boot carpet were also deleted, and distinctive light-weight headlights were fitted. 'N1' cars also had reinforcing for the brake master cylinder and additional brake cooling ducts under the car. All 'N1' cars were delivered with a thin layer of colour code 326 "Crystal White" paint.

To celebrate the success of the GT-R in both Group N and Group A racing, Nissan introduced the Skyline GT-R V·Spec ("Victory SPECification") package on 3 February 1993. The V·Spec added Brembo brakes and a retuned ATTESA E-TS system. The V·Spec was available in both 'plain' and 'N1' variants, with all V·Spec cars using the lightweight aluminium bonnet and front bumpers from the 'Nismo'. The cars also replaced the standard 16" wheels with 17" BBS wheels with 225/45R17 tyres. The V·Spec had a list price of ¥5,260,000.

Finally on 14 February 1994, the Skyline GT-R V·Spec II was released, with the only change being wider 245/45R17 tires. The 'plain' V·Spec and V·Spec II had a curb weight of 1,480 kg (3,256 lbs), weighing 50 kg (110 lbs) more than the standard GT-R. Total production of the V·Spec and V·Spec II was 1,396 and 1,306 units respectively.

Production of the R32 Skyline GT-R ceased in November 1994 after a production run of 43,937 units.

The most popular colors are KH2 "Gun Grey Metallic" (45% of cars), followed by 326 "Crystal White" (18%), 732 "Black Pearl Metallic (13%), KL0 "Spark Silver Metallic" (12%). The rarest color is BL0 "Greyish Blue Pearl" with only 141 units.
