The Z-Tune Skyline was designed by Nismo (Nissan Motorsports Division) to be the ultimate track car. It was specifically built to be driven at 100% for thirty minute track sessions. Because the R34 had been out of production for several years, Nismo bought up several used cars with low mileage, and used them as the base for the Z-Tune models. Only twenty were produced.
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. Engine displacement has been increased from 2.6 to 2.8 liters.
A serial number is applied to each of the 20 RB26DETT modified Z2 engines. In the future, this will be used for data management.
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.
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).
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.
