NISSAN SKYLINE BNR34

R34 GTR
The legendry GTR R34 with RB26 DETT engine. Only 80 official R34's were imported into the UK. With no more than a couple hundred GTR on the road. For those in the know, the Nissan Skyline GT-R needs little introduction. The Skyline GTR is Japan's most popular sports car. This envy-inspiring automobile, comes with a 280-horsepower inline 6-cylinder engine, It is powered by a high-tech (intercooled) twin turbo 2.6 litre in-line six which produces 280hp@6800rpm and 36.8kg/m @4400rpm. All-wheel-drive and twin turbos. Don't believe the 280bhp claimed figure from Nissan Japan, its near 330bhp from factory


The Nissan Skyline GT-R has consistently offered absolute enjoyment through the ultimate in driving pleasure. The GT-R's features are world class, this is an example of what all cars should be. Variable four wheel drive for optimum traction, maximum acceleration and maximised torque efficiencies. Four wheel steer for tight cornering, and ultimate control. Healthy 2.6 litre twin-turbo in-line 6 cylinder engine, 6 speed gear box for a full gear ratio, 18-inch rims for minimum tyre side wall flex and a nice solid ride.


The R34 communicates better at the helm than previous skylines. It’s easier to place and, with its tighter body and suspension control, Godzilla under steers less through the fast curvy bits. With stronger torque, new six-speed box plus the usual GT-R attributes of phenomenal 4WD traction and stopping power, the GT-R again qualifies as a simply fantastic driver’s car.

Previous GT-Rs were brilliant in fast sweepers but demanded rather more attention in tight corners. The R34 feels immediately wieldy and playful, the steering low geared (just 2.6 turns between locks) but wholly precise and full of feel. Weighty too, but then that’s another GT-R characteristic that’s part of the package.

Under the hood


The engine is a refined version of the all powerful RB26DETT, performance has been boosted by the increase of 15.6kg-m/litre of engine torque, (this is the best per-litre figure of any domestically produced 6-cylinder engine displacing over 2.0 litres.) In comparison to the engine used in the R33 GT-R, the camshafts have been modified to improve valve timing, which has enabled the increase just mentioned. Contributing to this are the new twin ball bearing ceramic turbochargers, which deliver sharp instant acceleration

The 6-speed Getrag gearbox combines close ratio gearing adopted for first through to fifth speed ranges, the R33 featured close ratio for first through to fourth in it's five speed box. Lever rigidity has been increased and shift effort reduced to provide a strong and direct feel to the drive.

The standard GT-R feature of LSD (or formerly known as helical limited slip differential) improves responsiveness, controllability and ultimately traction. A nice addition to the R34 is the exhaust pressure-sensitive control. The exhaust features stainless steel tailpipes with a larger bore. Ultimately this has reduced back pressure increase the capacity to breathe and ultimately more torque.



Handling

The R34 GT-R has one of the highest levels of body stiffness in the world. This contributes to a nice solid ride, and no loss of energy in body flex. The electric powered HICAS system is used to provide direct and impressive response to the drivers steering wheel input. The system's operation is based on the vehicle speed and steering wheel input, this control procedure determines the target vehicle state and the rear wheel steer angle needed to achieve the state that is determined. This provides the ultimate in tracking performance and control. Once again the GTR sports a full set of Brembo brakes. Brembo braking performance has been enhanced by changing the brake cooling system for greater anti'fade capability during hard driving. All models are equipped with 245/40ZR18 Potenz tires developed specifically for this GTR. This addition has made a weight saving of 4kg per vehicle alone.



Aerodynamics

The rear spoiler has been changed from a single-wing angle-adjustable type to a dual-level type with the angle adjustment mechanism made up of a main wing and a variable wing. Made of an aluminium for lightweight construction, the variable wing expands the range of down force adjustment without increasing aerodynamic resistance. It allows 4-way adjustments at a 10 pitch over a maximum range of 30, compared with 18 on the previous R33 GT-R model.


The GT-R V-spec model has a front diffuser and a carbon fibre rear diffuser to create down force for regulating the air flow along the car's under surface, allowing positive use of aerodynamic force for enhanced handling and stability. This improves straight-line direction, especially at high speeds above the 80mph mark, and stability during cornering and braking, by producing a force for actively pushing the body down toward the road while maintaining a before-and-after aerodynamic balance. Moreover, since the air flow under the floor is controlled, fluttering noise under the car is also substantially reduced during high-speed travel at speeds above 80mph.



Interior

The R34 features a 5.8" liquid crystal multi-function display at the top of the centre console. Seven items are presented in 3 modes. The select menu features in-depth information on the boost, oil temp, front torque, voltage, throttle, injectors, exhaust temperature, and intercooler temperature.


The next mode gives figures on the red zone of the gauge scales, how regularly and how hard you're pushing the vehicle. This can be reset at any stage to allow for online information to be monitored. The final mode, gives the driver an indication of exactly where the vehicle is in the gear ration, and advises the driver of the optimum time to shift up or down.

The gauge display has the tachometer positioned on the left hand side for instant and easy recognition of important RPM and vehicle speed information. Once again Monoform bucket sets have been attributed to the interior, but this time the seats have been specifically designed for the GT-R. They feature a large shoulder and side support to provide greater lateral support. An anti-theft immobiliser has also been installed, this system matches the internal code to the key code before the vehicle can even be started.

Engine produces the same power as a standard one (officially), but has lots of potential for tuning. All the bottom end is completely balanced to very fine tolerances something the N1 GTRs didn't even get!) and you can really feel it! N1 turbines have metal internals so produce more lag but better top end power delivery. These can also be used to achieve 500ps.
