Nearly a week after unable to control his newly reborn Eight-Six, Wataru finally found the reason Takumi was unable to use the full power of his new engine. He suggests him to install a high rev tachometer, water pressure and oil temperature gauges to unlock it's full power. After the installation of those important parts, Takumi is ready to accept Wataru's challenge and chose to race at his home turf at Shomaru Pass. Wataru chooses to run the race as an endurance race where the leader and chaser switches positions each round. If the chaser overtakes the leader then they will win the race as well as ending it. But if the chaser gives up or falls behind then he will lose.
During the Battle[]
Wataru's turbo boost as he chases Takumi
Ditto, Final Stage
Takumi passes Wataru
First 2 rounds, Takumi realises how much power his Trueno has and starts to adapt to the new changes faster. After 5 rounds, Takumi attempts to overtake Wataru by coming alongside him, something that he claims is impossible. In his shock, he pauses, allowing Takumi to pass. In Second Stage this is changed to Takumi driving on a mudslide, sending his car airborne.
After the Battle[]
The Akiyama siblings return to Saitama and Itsuki becomes heartbroken, unable to admit his feelings for Kazumi. Takumi then sees Natsuki working in a part time job. Ryosuke sends an open invite to any racers to be part of his new race team by devising a time trial at Akagi.
This is the first battle of the series to take place in a prefecture other than Gunma.
In Second Stage, Ryosuke, Keisuke, Kenta, Kenji, and Iketani all witness the race. In the Manga, there are no spectators.
This creates an inconsistency in Third Stage, as these characters react as though they hadn't seen Takumi racing in the newly upgraded Eight-Six like in the Manga.
The song "Deja Vu" played in the very end of this battle is considered to be a viral internet meme used on cars drifting, crashing, or anything fast.
The carbon fiber hood shown on Wataru's car against Takumi in Final Stage Outro
There is a small mistake in the final stage outro where Wataru's 86 had a carbon fiber hood on it despite the race took place before he upgraded his 86 to a supercharger.
