Kousoku Sentai Turboranger (高速戦隊ターボレンジャー, Kōsoku Sentai Tāborenjā), translated as High Speed Squadron Turboranger, was the 13th entry of Super Sentai series produced by Toei Company and Bandai. It was aired on TV Asahi on February 25, 1989 to February 23, 1990 with a total of 51 episodes.
On its first episode, Turboranger was celebrated as the 11th Super Sentai with a teamup of the previous 10 Super Sentai, even though by modern count, they are the 13th team. This was because at the time of the show's debut, Toei had the Super Sentai series begin with Battle Fever J. However, when Toei marketed Chouriki Sentai OHRanger as the 20th anniversary of the Super Sentai series, Toei retroactively included Goranger and JAKQ as part of the Super Sentai series. (Wikipedia)
