MF Ghost
The 991 GT3 appears in MF Ghost as the car of choice for Ishigami Fuujin, the number one driver for MFG. It appears to have been heavily modified, as stated in the manga, and has a colossal amount of horsepower and handling ability, as it was specifically designed for such racing events.

Trivia

 * Porsche cars appear twice in the manga, once in the form of the 991 GT3 driven by Ishigami Fuujin and in the form of the 718 Cayman S driven by Mikhail Beckenbauer.
