Read this and LEARN
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 GTR V-Spec II.
It was built with a concept RB26DETT 'Z1' engine. The cylinder
diameter was bored out, and the crankshaft was designed with a
longer stroke. The engine was now a 2.8L, and produced about
500hp.
Nismo was then given the approval from Nissan to build 20 Z-tune
models. For the 20 production models, the 2.8L engine was revised
to allow it to reach 9000rpm. The turbochargers were supplied by
IHI in Japan. The engine is advertised as making as much as 500hp.
This second revision of the Z-tune engine is called the 'Z2'. The
bodywork is designed with the same functional components used in
Nismo's GT500 racing cars, such as engine bay vents on the hood and
fenders, as well as wider fenders for wider wheels. The Z-tune is
also improved with an aggressive suspension setup, and a specially
designed Brembo brake setup.
The entire car is essentially handmade, with the car being
completely stripped and re-built from the chassis up. Engineers
reinforced and stiffened the chassis in key areas, completely
redesigned the suspension, drivetrain, engine, gearbox and other
componentry so as to work at maximum efficiency and reliability as
is expected of a road-going vehicle. Only 20 units exist worldwide
and is often regarded as the most expensive (prices for some have
been known to exceed AU$500,000) street legal GT-R ever
built.
