Nissan Nismo R34 Z-Tune lap time at Tsukuba

This is not a Production car, this is a Recycled used car turned into a GT500 Race car without a roll cage. First of all when Nismo build this car the GTR was no longer on production, they buy it used with less than 30k km and tuned, it Doesnt have the RB26, it has a Z2 Derived from the Lemans/GT500 it has more than 500hp, Sachs made a specific racing suspension for this car, carbon fiber axle, Rays LM lightweight wheels, and a aerodinamic Carbon Fiber kit. Basically a Lemans/GT500 with no roll cage, just a crazy thing like the Renault Espace F1 or the BMW X5 V12.

So this 2004 tuned car is faster than the 2017 GT-R with 70 PS more?

@ FastestLaps: But I do see where Z means to say, it seems hard to believe that a Nissan GTR can beat a Lamborghini Gallardo around a track, but I've learned on this site that the Nissan GTR is surprisingly fast.

If the boss-man says it's correct, I say it's correct, he's not wrong very often.

Why? Whats so special about 500hp Skyline posting a good time?

This time must be fake.
