Kizuna no Allele

Tomoe Shiro, a formidable racer with a very promising career, experiments a U-turn when a serious accident puts his life at stake. He recovers miraculously though when his heart is replaced with the engine of his own racing car. However, because of that very reason, race regulations demote him to the category of a mere mechanical part of the vehicle and is deprived from the right to participate as a pilot in regular races. Only in a far away colonial planet, along with a multitude of other charismatic pilots also vetoed from participating in regular competitions, will he be given the opportunity to race for his pride and the money of the prize. And so this exciting rally starts!! (Source: Official website)

Accumulating an impressive series of victories with his AE86, Takumi Fujiwara has imposed himself as street racing's newest rising star. However, his newly found confidence of winning at his home turf of Mount Akina has been put in jeopardy by a new Emperor team exclusively using a car model favored by most professional racing pilots: the Mitsubishi four-wheel drive Lancer Evolutions—also known as Lan Evos. The Emperor team leader, Kyouichi Sudou, looks down on Takumi and regards him as an inferior pilot for driving an antique car that lacks the makings of a true modern race car. Kyouichi's elitist philosophy is also the reason why his team is only made of Lan Evo drivers. Will Takumi be able to keep his perfect track record intact against the highly skilled and mechanically superior Emperor team, or does his hot streak end here? [Written by MAL Rewrite]

Based on a seinen manga by Kusunoki Michiharu serialised in Young Magazine. The story gets its roots from the actual street racing that occurs on Tokyo's Shuto Expressway, one stretch of which is known as the "Wangan", literally meaning "bay side" (although it is generally used to refer to the freeway), the longest, straightest road in the entire country. Of course, there's also lots of traffic to contend with, including a fair number of heavy trucks. Because of this, the action is inherently hazardous, and wrecks are common. Blown engines are also a frequent hazard, especially with the extreme-high power engines. One day, Akio Asakura, a third year high school student, is driving his Fairlady Z (Z31) and is challenged by Tatsuya Shima, a doctor, in his black Porsche 964 Turbo (nicknamed the "BlackBird"). With a friend in the passenger seat and two girls in the back, Akio pitifully tries to win, but is defeated. Determined to become faster, he goes to the junkyard to buy parts for his car, when he sees a pristine, unscratched midnight blue Fairlady Z (S30) in the junkyard. Intrigued as to why such a machine is about to be junked, he buys it. He soon finds that the car is unnaturally fast due to a tuned L28 engine, bored and stroked to 3.1 liters combined with twin turbos, which produces 620bhp. He also finds that all of the car's previous owners had unfortunate accidents in it, starting with the first owner's death. The manga follows Akio's various encounters, though the central plot revolves around his constant battle with the BlackBird for superiority. (Source: AniDB)
