The Mazda RX 7 is a car that I know very well, it has a twin turbo rotary engine and it's one of the stars of my favourite animes and manga, INITIAL D . I don't know if this body kit really exist, however the original rx 7 has foldable light lamps, and when a kit like this is added one of the lamps is made "blind" because of an additional air intake for the turbo. It would be a nice touch if you'll add something like that to your cars.
