There are only four people allowed to build engines for Nissan's GT-R. They are respectfully called "takumi", a word that describes them as a master craftsman who has perfected his skills over many years of hard work and dedication.

Nissan’s engine factory in Yokohama only has four such master craftsmen and they have a combined experience of over 100 years of work in their field.

Takumi Kurosawa, Tsunemi Ooyama, Izumi Shioya and Nobumitsu Gozu are the only people who assemble the 545hp twin-turbo V6 engines that power the GT-R by hand.

You can find out more about the craftsmen's work in the video below.
