The Nissan Skyline GT-R is a Japanese sports car based on the Nissan Skyline range.

The first cars named "Skyline GT-R" were produced between 1969 and 1972 under the model code KPGC10, and enjoyed legendary success in local Japanese touring car racing. This model was followed by a brief production run of second-generation cars, under model code KPGC110, in 1973. After a 16-year hiatus, the GT-R name was revived in 1989 as the BNR32 ("R32") Skyline GT-R. This model GT-R proceeded to win the Japanese JTCC Group A series championship four years in a row. The R32 GT-R also had success in the Australian Touring Car Championship helping the R31 Skyline GTS-R to victory in 1990 and winning alone in 1991 and 1992, until a regulation change excluded the GT-R in 1993.

The formidable technology and performance of the R32 GT-R prompted the Australian motoring publication Wheels to nickname the GT-R "Godzilla" in its July 1989 edition.

The Skyline GT-R became the flagship of Nissan performance, showcasing many advanced technologies including the ATTESA E-TS AWD system and the Super-HICAS four-wheel steering. Today, the car is popular for import drag racing, circuit track, time attack and events hosted by tuning magazines. Production of the Skyline GT-R ended in August 2002. The car was replaced by the R35 Nissan GT-R, an all-new vehicle based on the V36 Skyline. Although visibly different, the two vehicles share similar design features and are manufactured in the same factory.

The Skyline GT-R was never manufactured outside Japan, and the sole export markets were Hong Kong, Australia and New Zealand, in 1991, and the UK (in 1997, thanks to the Single Vehicle Approval scheme) as used Japanese imports. Despite this, the car has become an iconic sports car, including in countries from the Western World (mainly the United Kingdom, Australia, New Zealand, South Africa, Ireland, Canada, and the United States). It has become notable through pop culture such as The Fast and the Furious series, Initial D, Shakotan Boogie, Wangan Midnight, Need For Speed series, Forza series, Driving Emotion Type-S, and Gran Turismo series.

The car was named at the time by BBC's Top Gear as the only true Japanese contribution in the line of supercars, and by Jeremy Clarkson as one of the best cars in the world.

History of the brand

The Skyline name originated from Prince automobile company, which developed and sold the Skyline line of sedans before merging with Nissan-Datsun. The GT-R abbreviation stands for Gran Turismo Racer while the GT-B stands for Gran Turismo Berlinetta. The Japanese chose to use Italian when naming the car - as most cars that were made in Japan at that time used Western abbreviations - to further enhance sales. The earliest predecessor of the GT-R, the S54 2000 GT-B, came second in its first race in 1964 to the purpose-built Porsche 904 GTS. However, the earlier Prince Skyline Sport coupe/convertible foreshadowed the GT-R as the first sports-oriented model in the Skyline range, hence the name.

The next development of the GT-R, the four-door PGC10 2000 GT-R, scored 33 victories in the one and a half years it raced, and by the time it attempted its 50th consecutive win, its run was ended by a Mazda Savanna RX-3. The car took 1000 victories by the time it was discontinued in 1972. The last of the original GT-Rs, the KPGC110 2000GT-R, used an unchanged S20 119 kW (160 hp) inline-6 engine from the earlier 2000 GT-R and only sold 197 units due to the worldwide energy crisis. This model was the only GT-R to never participate in a major race despite the sole purpose-built race car, which now resides in Nissan's storage unit for historical cars in Zama.

The Skyline continued into the 1990s when it became popular largely because it remained rear wheel drive, while most other manufacturers were focusing on front wheel drive cars.

Throughout its lifetime, various special editions containing additional performance-enhancing modifications, were released by Nissan and its performance division Nismo (Nissan Motorsport).

Generations

First generation (1969-1972)

The first Skyline GT-R, known by the internal Nissan designation PGC10, was released on 4 February 1969, and was exclusive to Japanese Nissan dealership network called Nissan Prince Store when the Prince company was integrated into Nissan operations in 1966. It was available originally as a four-door sedan after a public debut at the October 1968 Tokyo Motor Show. It was advertised alongside the Nissan R380 racecar to showcase the Skyline's racing heraldry. It was equipped with the 2.0 L DOHC S20 I6 producing 160 hp (120 kW) at 7000 rpm and 177 N?m (131 ft?lbf) of torque at 5600 rpm. Power was delivered to the rear wheels by a 5-speed manual transmission. The first Skyline GT-R rode on a semi-trailing arm strut suspension. It was available as a coupe in March 1971 with the chassis code KPGC10.

A popular name for the PGC and KPGC10 Skyline GT-R was "Hakosuka," which combines the Japanese word for box ("hako" or ??) and the pronounced abbreviation of skyline ("Suka" or ?? as in ?????? or "sukairain").

A total of 1,945 PGC and KPGC10 Skyline GT-Rs were produced.

Second generation (1973)

The KPGC10's successor, the KPGC110, was released in 1973 after its introduction at the 1972 Tokyo motor show. Powered by a 1989 cc I6 S20 engine, the second generation GT-R delivered power to the rear wheels through a 5-speed manual gearbox. This car also had both front and rear disk brakes. The suspension was a semi-trailing ring arm setup and minor aerodynamic parts were added.

This edition of the GT-R was also known as the "Kenmeri" Skyline, due to a popular advertisement featuring a young couple (Ken and Mary) enjoying the Hokkaido countryside. The advertisement later spawned a hit song by Buzz, and the tree featured in the advertisement later became a minor star itself.

Unfortunately, the second generation GT-R was unsuccessful, for a gasoline crisis hit in the early 1970s, drying out any demand for high-performance sports cars. A total of 197 cars were built by the end of its short production run. For the next decade, this was the last GT-R until the production of the R32 in 1989.

Third generation (1989-1994)

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 tyres. 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 spin up of 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 N1 racing 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 tyres. 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 colours 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 colour is BL0 "Greyish Blue Pearl" with only 141 units.

Production figures

• GT-R (Series 1) = 17,316
• GT-R Nismo = 560
• GT-R Australia = 100
• GT-R (Series 2) = 11,187
• GT-R (Series 3) = 11,827
• V·Spec = 1396
• V·Spec II = 1306
• N1 = 245 (GT-R N1 = 118, V·Spec N1 = 64, V·Spec II N1 = 63).
• Total = 43,937

Fourth generation (1995-1998)

The E-BCNR33 (R33) was developed in 1995 as a successor to the R32 model. The engine in the R33 was nearly identical to the R32. It used the same turbochargers and the same specification for the manual gearbox, although the syncros were stronger. The engine corrected the R32's weak oil pump drive collar, which tended to fail in higher power applications, by using a wider collar. The base model R33 GT-R weighs 1,540 kg (3,400 lb).

The R33 GT-R launched in January 1995 with the base model GT-R and the V·Spec model. The V·Spec model weighed in 10 kg (22 lb) heavier, and had sportier suspension resulting in lower ground clearance. The V·Spec also featured the newer ATTESA E-TS Pro all wheel drive system, which included an Active Limited Slip differential. The V·Spec model also included a four-wheel independent channel anti-lock braking system.

At the same time as the release of the R33 GT-R and GT-R V·Spec, Nissan released the R33 GT-R V·Spec N1 model. Changes made in the R33 N1 are similar to those in the R32 N1. The car was made lighter by removing the ABS, air conditioning, sound system, rear wiper, and boot carpet. The R33 GT-R V·Spec N1 received the slightly revised R33 N1 engine.

The R33 ended production on 9 November 1998. The last one that rolled off the line came in a bay side blue.

1996 NISMO - LM Limited

There were several limited editions of the BCNR33 produced by NISMO - Nissan's Motorsport division. The first, the LM version, was released in May 1996 to celebrate Nissan's participation in the 24-hours of Le Mans. The only body colour available for the R33 LM was Champion Blue. The car had a front splitter lip to direct air to the upper front aperture, and a carbon fibre rear wing with Gurney flap. There were carbon fibre inserts on the rear wing fins with a GT-R badge on the inserts. The "GT-R Skyline" logo under the checkered flag was placed on the C-pillars.

Nissan produced just 188 of this model, 86 GT-R LM and 102 V-Spec LM. Nissan entered two R33 GT-R cars in the 1995 Le Mans 24 hour race where the number 22 car finished tenth overall. This was remarkable considering it was essentially running the same RB26 motor and going up against supercars of that era like the mighty Mclaren F1 GTR.

• Championship Blue (code BT2).
• Carbon Fibre Rear Wing Blade.
• N1 Front Brake Cooling Ducts.
• N1 Bonnet Lip.
• Commemorative GT-R Decals on C-Pillars.

1997 NISMO 400R

A special edition R33 was released on 3 November 1997 called the 400R, with R standing for Racing. Overall development and planning was by NISMO (Nissan Motorsports International). But, its bored and stroked RB26DETT engine, the RBX-GT2, was engineered and produced by REINIK (later renamed REIMAX - "REINIK to the MAX"). The engine featured 77.7 mm stroke crankshaft (73.7 mm stock), forged 87 mm pistons (86 mm cast stock), upgraded rods, polished ports, high lift camshafts, upgraded oil system, larger exhaust manifolds and higher output turbochargers. NISMO produced an upgraded exhaust, a twin-plate clutch, and intercooler system. Nismo brake pads were fitted to the car. 400R exclusive aerodynamic updates were also added, such as wider bumpers, side skirts, a new rear bumper, a new front bumper with bigger air scoops, and a redesigned bonnet and rear spoiler made of carbon fibre. The 400R was also fitted with 18x10 Nismo LM-GT1s. The car developed 300 kW (400 hp) and 347 lb?ft (470 N?m), which allowed a top speed of over 300 km/h (186 mph), and enabled it to reach 0-97 km/h (0-60 mph) in 4.0 seconds. 370 kW (500 hp) is easily achieved with a higher boost setting. NISMO had originally planned to produce 100 units of the 400R, however only 44 units were made before production of the R33 ended in 1998.

Production figures

• GT-R (Series 1) = 5050
• V·Spec (Series 1) = 4095
• Unknown (Series 1) = 14 (Pre-production or early cars including GT-R, V·Spec and V·Spec N1).

Fifth generation (1999-2002)

The GF-BNR34 (R34) Skyline GT-R, GT-R V·Spec and GT-R V·Spec N1 models were released in January 1999. The R34 GT-R was also shorter (from front to rear), and the front overhang reduced. The valve covers were painted glossy red (colour code Cherry Red Effect Z24 or X1020), as opposed to black in previous models.

A new feature on the R34 GT-R is a 5.8" LCD multifunction display on the center of the dashboard, which shows seven different live readings of engine and vehicle statistics such as turbocharger pressure (1.2 bar max), oil and water temperature, among others. The GT-R V·Spec model added two extra features to the display: intake and exhaust gas temperatures. Nismo Multi-function Displays (MFD) can be bought at an extra cost, they include a lap timer, G-Force meter and an increase in boost pressure measurement to 2 bar. The R34 GT-R was made shorter in response to customer concerns who thought the R33 was too bulky.

Like the R33, the new R34 GT-R V·Spec (Victory Specification) models come equipped with the ATTESA E-TS Pro system and an Active LSD at the rear, while standard GT-R models come with the non-Pro system and a conventional mechanical differential. The V·Spec model also had firmer suspension and lower ground clearance, thanks to front and side splitters, as well as a rear carbon fibre air diffuser, designed to keep air flowing smoothly under the car.

At the time of the R34's release, like the R32 and R33, Nissan released an R34 V·Spec N1 model. The R34 V·Spec N1 was equipped similar to the R32 and R33 N1 models - a homologation special. It was sold without air conditioning, audio equipment, rear wiper, or boot lining, but ABS remained. The new R34 N1 was also given the new R34 N1 engine. Only 38 known R34 V·Spec N1 models were produced from the factory, 12 of which Nismo used for Super Taikyu racing. The rest were sold to various customers, mostly racing teams and tuning garages.

The V·Spec version was also imported into the UK with a number of modifications carried out on these 80 cars. These included 3 additional oil coolers, revised ECU map, full Connolly leather interior, underbody diffusers, stiffer suspension, active rear limited slip differential, extra display feature on the in car display. In additional to the UK, 10 were sold to Hong Kong and Singapore, and 5 to New Zealand although with different changes for their respective markets.

In October 2000, Nissan released the V·Spec II, replacing the V·Spec. The V·Spec II has increased stiffness in the suspension (even stiffer than the original V·Spec) and had larger rear brake rotors. It also comes equipped with a carbon fibre bonnet equipped with a NACA duct, which is lighter than the aluminum that all other GT-R bonnets are made from. Also different on the V·Spec II was an iridium center console and aluminum pedals. The seats were upholstered with black cloth rather than the gray cloth used on previous R34 GT-R models, and the amber turn lenses were replaced with white versions. With the exception of the carbon fibre bonnet, the standard trim level GT-R also received these updates. A total of 18 V·Spec II N1 were built. A total of 1855 V·Spec II were built for Japan, with an additional 2 being sold for the New Zealand market. The V·Spec N1 was replaced with the V·Spec II N1. The same changed applied to the V·Spec N1 were applied to the V·Spec II N1, with the exception of the V·Spec II carbon bonnet which was now unpainted.

In May 2001, the M·Spec was released. It was based on the V-Spec II, but had special "Ripple control" dampers, revised suspension set up, stiffer rear sway bar and a leather interior with heated front seats. The 'M' on the M·Spec stood for Mizuno who is the chief engineer of Nissan. The only other change was the removal of the carbon fibre bonnet which was replaced with the standard aluminium bonnet.

In February 2002 Nissan released a final production model of the R34 GT-R called the Skyline GT-R V·Spec II Nür and the Skyline GT-R M·Spec Nür. The Nür was named after the famous German Nürburgring racetrack, where the Skyline was developed. In total 1003 R34 GT-R Nür(s) were produed, 718 were V·Spec II Nürs' and 285 were M·Spec Nürs'. The Nür model featured an improved RB26DETT based on the N1 racing engine. The standard turbochargers were upgraded to larger versions with a slight increase in boost and the ceramic blades were replaced with steel versions. This has increased lag, but to compensate the turbo's durability was improved while being able to handle a bigger boost increase. This allowed tuners to increase the boost safely with standard turbos up to 340 kW (450 hp) at the crank. The V·Spec II Nür is based on the regular V·Spec II model, and the M·Spec Nür was based on the regular M·Spec model. Other than the addition of the Nür engine, the Nür models also included a different colour of stitching on the interior trim, as well as a speedometer reading up to 300 km/h (186 mph), gold valve covers instead of red and a gold VIN plate instead of silver. Due to Japanese car industry norms at the time, the car was advertised as having 206 kW (276 hp) but it actually had over 246 kW (330 hp) when it left the factory.

Z-Tune

Nismo originally designed the concept of the Z-tune in 2002 when Nissan was putting an end to the R34 Skyline production. The first Z-tune was built in 2003, using a used 2002 Skyline GT-R V·Spec II. It was built with a concept RB26DETT 'Z1' engine. This engine was based on Nissan's Le Mans GT2 and GT500 racing experiences. As with the racing vehicles a strengthened engine block and stroked crankshaft were utilised. The engine was also bored. With the new displacement of 2.8 L and upgraded turbo-chargers the Z1 produced 370 kW (500 hp). The Z-Tune had a 0-100 km/h (0-60 mph) time in 3.8 seconds and has a top speed of over 327 km/h (203 mph).

Nismo was then given the approval from Nissan to build Z-tune models for the Nismo anniversary. Nismo then purchased 18 used R34 GT-R V·Spec, each with less than 29,000 km (18,000 miles) on the clock, they were then completely stripped and were resprayed to a "Z-tune Silver," a special colour exclusively for the Z-tune. One car was left in its original colour of Midnight Purple III. For each of the 18 production models, the 2.8 L engine was revised to allow it to reach 8000 rpm. The turbochargers were supplied by IHI in Japan. The engine is advertised as making as much as 370 kW (500 hp) (for warranty reasons). This second revision of the Z-tune engine is called the 'Z2'. The bodywork is designed with the same functional components used in Nismo's GT500 racing cars, such as engine bay vents on the bonnet and bumpers, as well as wider arches for wider wheels. The Z-tune is also improved with an aggressive suspension setup from Sachs, and a specially designed Brembo brake system.

The entire car is essentially handmade, with the car being completely stripped and re-built from the chassis up. Engineers reinforced and stiffened the chassis seam welding in key areas such as the door seams and door frames and added carbon fibre to the strut towers and transmission tunnel and the engine bay, completely redesigning the suspension, drivetrain, engine, gearbox and other components so as to work at maximum efficiency and reliability as is expected of a road-going vehicle. Although Nismo planned on building 20 cars, they ceased production on only 19 (including 2 prototypes). The Z-tune is often regarded as the most expensive (prices for some have been known to exceed US$290,000) street legal GT-R ever built.

Replacement

Following the end of R34 production in 2002, Nissan announced they would separate the GT-R model from the Skyline name, creating an entirely new vehicle--though based on the same platform as the Skyline. This new car, now known simply as the Nissan GT-R, debuted in 2007 in Tokyo. Released to consumers in 2008, it was the first GT-R available worldwide, entering the North American market for the first time.

Though based on the FM platform used by the V36 generation Skyline, the GT-R uses an evolved Premium Midship (PM) platform. The car retains its heritage by using the chassis code DBA-R35, or simply R35.

Powertrain

The GT-R of the 1990s included a 2.6 L straight six-cylinder twin-turbo engine producing 206 kW (276 hp). The stock turbo-chargers were of a hybrid steel/ceramic design allowing them to spool up faster due to the light nature of the ceramic exhaust wheel.

The drive train delivered power to all four wheels using an electronically controlled all-wheel-drive system Nissan called the ATTESA E-TS. The ATTESA E-TS system used two accelerometers mounted under the center console, which fed lateral and longitudinal inputs to the ECU. The ECU then controlled power delivery to the front wheels via an electronic torque split converter. In 1995, the ATTESA E-TS Pro was introduced as an option for R33 GT-R customers, and came as standard equipment in GT-R V.spec models. It was later standard equipment in all GT-R models for the R34 Skyline GT-R. The ATTESA E-TS Pro added an Active Limited Slip Differential, which was controlled by the onboard ATTESA computer. This was only for the rear differential, as the front differential remained as a normal Limited Slip Differential. The ATTESA E-TS Pro was also advertised in brochures as adding an electronically controlled 4-channel ABS brake system. Although it is not related to the all wheel drive system, it uses much of the same sensors, and the same computer. The R32 could be switched from AWD to RWD by removing the 4WD fuse, but R33 and R34 models had to have the front tailshaft removed, or the centre diff can be depressurised for 'towing mode' as specified in the owners manual.

The car also had computer-controlled all wheel steering system referred to as HICAS. The HICAS system activated when the vehicle exceeded 80 km/h (50 mph) and controlled the steering of the rear wheels in the same direction as the front to improve turn in on entry to corners. It should be noted however that this feature is often seen as more of a hindrance than help in race applications. The system tends to favor less advanced drivers, and can make the rear suspension unstable during high speed cornering. For this reason many kits are available to override this system. These kits usually loop the hydraulic lines back on themselves on the R32. Kits for the R33/34 models use a simple lock out bar--or a Tomei kit, which also alters the electrical control system ( the 33 and 34 had electronic HICAS). These modifications strive to make the car more predictable when driving at the limit of traction.

While the published figures from Nissan were as quoted above, tests showed the car had a factory power output of closer to 330 PS (243 kW; 325 hp) at the flywheel. The lower published figure was Nissan's response to the need to abide by a gentleman's agreement between the Japanese auto manufacturers not to release a car to the public exceeding 280 PS (206 kW; 276 hp) of power output.

N1 engines

RB26DETT N1 is an upgraded version of the standard RB26DETT engine. It was developed by Nissan Kohki's REINIK division for NISMO and N1 race cars. The standard RB26DETT, although known for its durability, proved to require too much maintenance for Group N (N1 class) racing conditions. REINIK started with a strengthened RB26DETT block. The N1 block is identified by its 24U number stamped on the block (05U standard blocks). The cylinder walls are thicker and water cooling channels are enhanced to increase flow. It also received an upgraded oil pump and water pump, to improve the cooling and lubrication for race conditions. The pistons have 1.2 mm (0.047 in) top rings and were balanced before assembly but otherwise very close to standard. The connecting rods are also similar to standard but made from slightly stronger material and balanced. Standard crankshaft is balanced to a higher level. Higher flow exhaust manifolds and turbochargers were added for increased torque and slightly higher top-end power. Turbine wheels on the N1 turbochargers are also made from steel for durability, rather than the lighter but weaker ceramic found on the standard turbine.

The R32 Skyline GT-R N1 street car marked the N1 engine's introduction to the consumer. R32, 33, and 34 N1 street cars were known for lack of amenities and their light weight. The R33 N1 engine and turbochargers were slightly revised, and the R34 N1 engine saw further improvement. The camshaft timing was altered slightly for more torque. R33 and R34 N1 turbochargers are the same size however R34 N1s use a ball bearing center section. NISMO states the ball bearings in the R34 N1 allow them to spool 400rpm faster than R33 N1.

The final N1 engine is the R34 Nür engine. The only differences are the cam cover colour change from red to gold and R34 Nür edition was a fully loaded street car. There were 1000 Nür engines made for use in the R34 V.spec II Nür and R34 M-spec Nür models.

The GT-R's history of racetrack dominance began with its 50 victories scored from 1968 to 1972, including 49 consecutive wins in the Japanese race circuit. Nissan pulled out of racing shortly after the release of the KPGC110.

The Skyline GT-R later earned the nickname "Godzilla", as a play on its "monster" track performance and country of origin. The R32 GT-R dominated JTCC, won all 29 races it entered in the series, as well as taking the series title every year from 1989 to 1993.

It took 50 races from 50 starts from 1991 to 1997 (latterly R33) in the N1 Super Taikyu. The GT-R's success sounded the death knell of Group A Touring Car racing; with the formula being scrapped soon after. JTCC was similarly dominated by the R32 GT-R, and splintered soon after, leading to the switch to the Supertouring category and also indirectly to the GT500 category of today.

The GT-R's success in motor racing was formidable, particularly in the annual 1,000 km (620 miles) race at the Mount Panorama circuit in Bathurst, Australia, where the winner in 1991 and 1992 was a GT-R (despite receiving additional 140 kg (309 lb) in weight penalties and a turbo pressure relief valve in 1992, and crashing). It took the overall win of the 1991 Spa 24 Hours, after getting the pole position and fastest lap time, ahead of the Porsche 911 and BMW M3 Evolution. It remained dominant in the Japanese GT series for many years. The Skyline GT-R line was retired from the JGTC series (later changed Super GT Series) in 2004. Its successor, the Nissan GT-R, competed and dominated the 2008 Super GT season, winning the GT500 (see details below).

No other GT-R race victories escaped controversy. At the 1990 Macau Grand Prix Guia touring car race, the factory-backed R32, driven by Masahiro Hasemi, led the race from start to finish, which caused a wave of protests by European entrants. The following year, officials forced the car to carry a weight penalty of 140 kg (309 lb). That year, it was also up against the more competitive DTM BMW M3 and Mercedes-Benz 190E 2.5-16 Evolution II. A disgruntled Hasemi took fourth place. For the following and final year, the weight penalty was reduced, and works-backed Hasemi returned with another privateer R32. The privateer crashed, and Hasemi retired with engine failure.

In the UK, Andy Middlehurst took the Nissan Skyline GT-R (R32) to two consecutive championship wins in the National Saloon Car Cup. Other championship titles include the 1991 Australian Touring Car Championship (Jim Richards), the 1991 Australian Endurance Championship (Mark Gibbs & Rowan Onslow), the 1991 Australian Manufacturers' Championship, the 1992 Australian Touring Car Championship (Mark Skaife) and the 1992 Spanish Touring Car Championship.

Akira Kameyama has taken the GT-R to the Pikes Peak International Hillclimb race on three occasion winning in each Open Class for production cars he entered, one in 1993 with the R32, another in 1996 with the R33 and again in 1998. For the following year, Rhys Millen took an R33 Skyline GT-R to win the High Performance Showroom Stock category.

The GT-R debuted in the US at the 1994 Rolex 24 Hours of Daytona. Nismo entered a sole Group A specification R32 for the GTU category, which finished 20th.

In 1995 Nismo developed the Skyline GT-R for endurance racing with a pair of JGTC specification R33s for the 24 Hours of Le Mans. To meet homologation regulations, Nissan had to build at least one street legal version. The two racing cars achieved some success at Le Mans, with one car placing tenth overall, and fifth in its GT1 class--beaten only by the more developed McLaren F1 GTRs and the GT2 class champion No.84 Honda NSX entered by Team Kunimitsu. For 1996, the Skyline GT-R LMs returned, this time carrying enlarged RB26DETTs displacing 2.8 litres. Again competing in GT1, they finished 15th overall, and 10th in class. However, Nissan chose to abandon their production-based Skyline GT-R LMs in 1997 and instead turn to the purpose-built R390 GT1s. In honor of the success of the Skyline at Le Mans, Nissan marketed a limited edition R33 they called the LM Limited, available only in "Champion Blue" (colour code BT2).

In 2006 Automotive Forums.com became the first team to compete with an R34 GT-R in the United States, participating in the Speed World Challenge GT series. Team: Driver and President of Automotive Forums.com Igor Sushko, Crew Chief Sean Morris, Team Manager Victor Reyes, Mechanic Josh Mitchell, and Engineer Merritt Johnson.

In 2007 the Heat Treatments Drag R32 Skyline GT-R driven by Reece McGregor of New Zealand, broke the world record for the fastest AWD over 400 m (¹/₄ mile) with a time of 7.57 seconds at 305.98 km/h (190.13 mph) at the Willowbank Dragway in Australia, a record previously held by the HKS R33 Skyline GT-R with a time of 7.67 seconds. Heat Treatments R32 has gone as quick as 7.53@185 mph.

On the same year at TOTB U.K Racing series, Keith Cowie and RB Motorsport's GT-R BNR32 broke the fastest four-wheel drive 0-300 km/h (0-186 mph) record with a time of 12.47 seconds. The previous record holder was another GT-R, a BNR32 from Veilside Japan with 13.72 seconds during the early 90s.

In March 2015, the New Zealand tuning shop, R.I.P.S., set a new AWD 400 m (¹/₄ mile) record with their BNR32 "RIPS MGAWOT III". It ran 7.32 seconds at 308.91 km/h (191.95 mph).
