Nissan Skyline GTR R34 T-Shirt Pin

Nismo originally designed the concept of the Z-tune in 2002 when Nissan was putting an end to the R34 Skyline production. The first Z-tune was built in 2003, using a used 2002 Skyline GT-R V·Spec II. It was built with a concept RB26DETT 'Z1' engine. This engine was based on Nissan's Le Mans GT2 and GT500 racing experiences. As with the racing vehicles a strengthened engine block and stroked crankshaft were utilised. The engine was also bored. With the new displacement of 2.8 L and upgraded turbochargers the Z1 engine was rated at 368 kW (500 PS; 493 hp) at 6800 rpm and 540 N⋅m (398 lbf⋅ft) of torque at 5200 rpm.[81][82] The Z-Tune had a 0–100 km/h (62 mph) acceleration time of 3.8 seconds and has a top speed of over 327 km/h (203 mph)
