Nissan Skyline R34 Z-Tune

Skyline GT-R Z-tune: The Ultimate Road-Going Car in the World

The basic concept for the NISMO Skyline R34GT-R Z-tune was finalized in 2000, and the vehicle made a splashy debut at the NISMO Festival. At that time, the vehicle was entered into a competition called the "Tuners' Battle," and it was victorious through its use of a maximum power of 600 bhp.

This prototype machine, which focused on providing complete driving performance, undertook a new challenge in the following year. The challenge was to add comfort as a road-going model. In addition to an authentic leather interior, air-conditioning, and a catalyst, the engine was also changed from the Z1 to Z2. Development trials and tests have already been completed for this prototype machine to mature the vehicle. In 2003, it was finally taken to the revered Nurburgring. Furthermore, the engine was used in the Nurburgring 24-Hour Endurance Race, where it proved itself, and in the 2004 race it won in its class and the overall 5th position. In addition, various unit parts continue to be employed and improved in a variety of applications, and in that year they reached perfection by winning the Tuners' Battle.

Because Nissan made the last Skyline in 2003, NISMO team had to find pre-owned GT-Rs. They were only interested in vehicles with no body damage and a mileage of less than 18,000. The cars were then stripped down to the bare metal and transformed into road-going racers.

Z-tune Concept Engine (Spec 2)

The heart of the NISMO R34GT-R Z-tune that exhibits such dominating performance is the RB 26DETT Modified Z2 engine.

To achieve an engine that generates more than 500 bhp and provide durability required from road-going cars, many techniques and know-how that NISMO accumulated throughout the racing scenes, have been lavishly adopted into this Z2 engine.

A serial number is applied to each of the 20 RB26DETT modified Z2 engines. In the future, this will be used for data management.

Z-tune Suspension Made by SACHS

Special tuning for "Z-tune" based on a damper made by SACHS (vehicle height, attenuation force, 3-way adjustment type) and which has been proven in GT500 vehicles was used for the suspension, which has a major impact on handling performance.

A wide range of driving conditions is supported by mounting S tires for high-speed driving on a closed circuit to mounting sports radials for street driving.

Special Z-tune Brakes Jointly Developed with Brembo

This brake system, which was developed for a target performance of 1.6 G when mounted with S tires, was jointly developed with Brembo. It features such parts as a mono-block 6-piston caliper (for the front), 2-piece front brake rotor with a O365 rotor system, and O355 mm one-piece rear brake rotor jointly developed with KIRYU. In addition, the ABS unit was specially tuned to further utilize the performance of these high-performance parts. The ATTESA ET-S and active L.S.D. were specially tuned to accompany the increase in engine power in order to make the torque distribution to the front more suitable and to improve the rear differential effectiveness, among other things, to stay true to the great handling of the base car Skyline GT-R (BNR34).

RAYS' GT500 Wheels

R34GT-R Z-tune rides on black LM GT4 "GT500 Model" lightweight forged aluminum wheels that were jointly developed with RAYS. This is a wheel with the same rim shape and color as used for GT500 race vehicles.

Only 20 GT-R Z-tune Skylines will be made.
