At the time of the R34's release, like the R32 and R33, Nissan released an R34 N1 model. The R34 GT-R N1 was equipped similar to the R32 and R33 N1 models – a homologation special. It was sold without air conditioning, audio equipment, rear wiper, or trunk lining, but ABS remained. The new R34 N1 was also given the new R34 N1 engine. Only 45 R34 V.spec N1 models were produced from the factory, 12 of which were used by Nismo for Super Taikyu racing. The rest were sold to various customers, mostly racing teams and tuning garages.
So in total. There really isn't many N1's built for this world of 6 billion people.
