Nearly two years after Nissan phased out the GT-R due to stricter emissions laws, Nismo, the company's motorsports arm, has brought back the R34 for one last encore performance. Only this time, it's standing ovation material....
Nissan's motor sport division NISMO has tweaked R34 Skyline GTR to glorious 500 hp road legal beast and the ultimate factory R34 Skyline is called Z-Tune. Sadly only 20 example has been produced and sold for over $250k.
