The R34 GT-R is perhaps Nissan’s most iconic motor vehicle and the pinnacle of the R34 series is the Z-Tune GT-R. Only 19 of these puppies were built (although Nismo planned on building 20) and they were built on used R34 GT-R V·Spec models with less than 29,000km on the clock. One of these found its way to the Gold Coast Motor Festival. Check out the footage below!
Nismo originally designed the concept of the Z-Tune in 2002, when Nissan was putting an end to the R34’s production. The first Z-Tune rolled out the factory in 2003 and Nismo was given approval to make another 18.
The cars were built with a concept RB26DETT ‘Z1’ engin, which was based on Nissan’s Le Mans GT2 and GT500 racing experiences. This came with a strengthened block and stroked crankshaft. Additionally, the engine displacement was increased to 2.8-litres and upgraded turbochargers were fitted, which gave the Z-Tune around 500HP. With all the extra power, the Z-Tune GT-R could go from 0-100km/h in 3.8 seconds and had a top speed of 327km/h (203mph).
Nismo stripped and resprayed the used V Spec GT-R’s to a “Z-Tune Silver”, which was a special colour that was exclusive to the Z-Tune. The bodywork was based off Nismo’s GT500 racing cars and was designed to be more functional. The changes to the bodywork included the bumpers, bonnet, engine bay vents, wider wheel arches for increased tyre size and more. Brembo designed a completely new brake system for the Z-Tune and the suspension system was upgraded for more aggressive driving by Sachs.
All of the Z-Tune GT-R’s were handmade and were 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. Carbon fibre was also extensively used in places like the engine bay, strut towers and transmission tunnel. As many of the components for the Z-Tune were based off racing gear, Nismo had to redesign many of them to work at maximum efficiency and reliability as is expected of a road-going vehicle.
The GT-R Z-Tune has become an incredible collectors item, with one fetching over $500,000 in Hong Kong.
