[edit] History
The Turbo-A was Toyota's evolution model for Group A touring car championships all over the world which required a minimum of 500 which were only sold in Japan and was produced in 1988. Some noted differences between the standard supra and the Turbo-A model are both cosmetic and some mechanical. The front nose features the ducting to cool the engine, the badging 'turboA' and a Black paint job (all 500 are black). The engine bay features a 267 bhp (199 kW) 7M-GTEU. All Turbo-As also came standard with leather interior.

[edit] Race History
The car didn't win as many races as hoped, being a 3.0 L it was forced to run with more weight where the R32 Skyline GTR didn't have the same restriction and was soon outmoded by the latter when it made its debut in 1990. For the JTCC Toyota would in 1991 switched to racing AE111 Corolla Levins in the lower category until the series final year in 1993. However in the less 'limited' racing it did considerably better.
