｢NISMO R34 GT-R Z-tune｣は、2000年にその基本コンセプトを決定。
プロトタイプ車を用いての開発・テスト、そして各パーツの実戦投入・改良が続けられ、ニスモが創立20周年を迎えた2004年に発売され、最終的に19台が生産されました。

Since the introduction of the R32 model in 1989, the second generation Skyline GT-R has racked up numerous victories in the race scene for about 15 years across the R33 and R34 models.

Based on the R34 model, which is the completed version of the second-generation Skyline GT-R, NISMO, which has developed race vehicles such as the "Gr-A," "N1," "GT500," and "Nur specification," and has continued to participate in races itself, has fully utilized the technology and know-how it has accumulated over 15 years.
The "NISMO R34 GT-R Z-tune" is a complete car built with the keywords "the world's most powerful road-going car" and "TOP OF THE GT-R."
The basic concept of the "NISMO R34 GT-R Z-tune" was decided in 2000.
Development and testing using a prototype vehicle, as well as actual use and improvement of each part, continued, and in 2004, when Nismo celebrated its 20th anniversary, 19 units were finally produced.
