The design team gave the LT6 engine the nickname
Gemini as used by NASA decades ago.
This is due to its use of twin 87 mm throttle bodies, twin cams, twin high-pressure fuel pumps, and other pairs of cool parts
NASA named the Gemini spacecraft and program after the constellation Gemini.
The name is Latin for
"twins."
NASA used this name because the Gemini capsule
would carry two people.
