The first Nissan Skyline H/T 2000GT-X appeared in 1971. This car was nicknamed Hakosuka (ハコスカ) by fans in Japan. Hako (ハコ) means 'Box' in Japanese, and suka (スカ） is short for 'Skyline', a nickname coming from the car's overall boxy shape and straight lines. The GT-X used the 2.0 L (1998 cc) S20 I6. This new DOHC (dual overhead camshaft) engine (which was designed by the former Prince engineers) produced 160 hp (118 kW, 180 N·m).

The 2017 release of the H/T 2000GT-X is based on a Skyline owned by Hot Wheels collector Roy de Guzman.
