After watching the "Initial D" movie, I noticed a problem. Takumi's dad put an illegal engine in the 86, but Ryosuke and Kyoichi's cars have large horsepower from the factory, which should be legal engines. In fact, in the movie, there's a line saying, "The FC's horsepower is too high, although it's limited to 250...," indicating they even restricted the power. So, did Takumi cheat?

Is it reliable to convert a naturally aspirated engine to a supercharged one? Is it even legal? I got all excited watching those videos. My little car turning into a 1.5T.
