The NISMO R34 GT-R Z-tune is the ultimate expression of the R34 platform. Built to celebrate NISMO's 20th anniversary, each Z-tune started as a carefully selected used R34 V-Spec with under 30,000 km, which was then completely stripped, inspected, body-reinforced, and rebuilt using the same handmade manufacturing process used for racing cars. The result is a level of accuracy and specification unachievable in mass-produced vehicles.

19 units total including the prototype. Two cars delivered to overseas customers. Originally planned as 20 units.
