Nissan Skyline GT-R NISMO Z-Tune up for Sale
There’s rare and there’s the Nissan Skyline GT-R Nismo Z-Tune. Just 20 of these ‘ultimate spec’ R34s were made back in 2005 in celebration of NISMO’s 20th birthday so the opportunity to buy one doesn’t come up all that often. But one is currently up for grabs from Hong Kong…
The inspiration for the project was based around the success of the R33 and R34s in racing across the globe, down in many respects to the RB26DETT engine and advanced ATTESA E-TS four-wheel-drive system. NISMO had been central in the development of these cars and over a 15 year period of the R33 and R34 had learned how to extract the best from them.
Initially the GT-R NISMO Z-Tune was a concept created in 2000 in race specification with a 600ps Z1 series engine. It was subsequently developed into a road-going concept, with a Z2 series engine, creature comforts and conformity with emissions regulations. A race-spec version with the same engine as the development car was raced at the Nurburgring 24-hours twice and in 2004 proved its mettle by taking fifth place.
Coinciding with NISMO’s 20th anniversary, the decision was made to build just 20 cars that would be available for the public to buy.
When NISMO set about this project production of the R34 had already ceased so Nissan’s tuning arm set about sourcing existing cars with low mileage and in a condition that met their exacting standards. Twelve were acquired and eight further cars donated by fans. They were then taken apart by hand, in the process being reinforced and improved before being repainted and reassembled. The front bumper, bonnet, side skirts, rear spoiler and bumper were replaced by carbon fibre reinforced plastic version. These had been modified to maximise air flow to where it mattered – the engine bay and brakes – as well as providing genuine downforce at speed. Reducing weight further was a carbon prop shaft which, at just 5.26kg, saved 7.26kg on its own.
Underneath the chassis on the Z-Tune was heavily reworked. Three-way adjustable dampers were developed by SACHS and supported lightweight GT500 forged alloy wheels. Z-Tune brakes by Brembo were created with the aim of achieving a retardation force of 1.6G. At the front 365mm rotors were combined with six-pot callipers while 355mm discs with four-pot callipers did the work at the back. 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. The aim, however, was to maintain the GT-R’s characteristics, but do so on a bigger, faster scale.
Of course the star of the show lurked under the bonnet. The race-derived RB26DETT in the GT-R NISMO Z-Tune put out 493hp (500ps) and just shy of 400 ft lb of torque. Each and every engine they built was made by hand and dyno tested to ensure it was producing what NISMO said it did. Unlike the standard R34 GT-R, the Z-Tune’s engine was over-bored and stroked to displace 2.8-litres. New cams, forged pistons and con rods were needed to handle the 21psi delivered by the twin IHI turbo chargers. A high-flow catalytic converter allowed the waste to escape through an exhaust so large in diameter that there was a very real possibility of losing small children up it.
The final car weighed in at 1,600kg and at the time astounded journalists with the breadth and depth of its abilities both on the road and on track. Official performance figures are hard to come by, but we know it will do a standing quarter in 10.06 seconds which is 0.74 seconds quicker than the 2013 R35 GT-R. So basically, it’s very fast indeed.

The one currently for sale is car number nine and is available to ship worldwide, having been registered in Hong Kong in 2006. It has covered just 3,100km (less than 2,000 miles) since new and is basically as it was delivered. What price can you put on such a car then? Well, the first R34 Z-Tune went to auction in 2015 with an estimate of £400,000. But when you think about the Nissan GT-R’s heritage, global following and the Z-Tune’s rarity, it is probably a very sound investment.
