Starting around 4:15 the video goes to the Kyushu plant and shows every single step of the production line for S13s. Unlike the video Nomuken did a few years later this was when the S13 240SX was still in production and several of the cars (including the one in the video thumbnail) are 240SXs or LHD 200SXs. Clear shots of a LHD CA18 engine bay and the part where it shows engine assembly they're making KA24Es. 12:25 in the video there's even unedited KA24E cold start sound! Love the engine test rig with minty new KAs and CAs side by side.
Lots of interesting details I never knew. When it shows a car going through the primer dip you can see that the under-taillight panel is attached to a fixture inside the trunk instead of attached to the shell.
