1 of 500 (1988 Toyota Supra “Turbo A”) here and home.
The Turbo-A was Toyota’s evolution model for [Group A] Japanese Touring Car Championships (JTCC) all over the world which required a minimum homologation run of 500 units which were only sold in Japan and was produced between August and September 1988. Thus the term 88 Spec A. Some noted differences between the standard Supra 3.0 GT and the Turbo-A model are both cosmetic and mechanical. The stock CT-26 turbo had a slightly larger inducer and can be identified by a stamped “E” on the raised casting on the compressor housing. The turbo-A had a 65 mm (2.6 in) throttle body and accompanied larger diameter crossover pipe, instead of the standard 7M-GTE 60 mm (2.4 in) and “3000” cast original unit. The Turbo-A also benefited from a larger volume steel air cleaner, instead of the factory plastic unit.
The fuel management used a MAP system, instead of the standard Karmen Vortex AFM. The front nose features an additional “Turbo A duct” to add airflow to the intercooler. Also unique was the side decal and rear badging (“3.0GT Turbo A”) and a black paint job (paint code 202). All Turbo-As came standard with grey leather interior featuring a Momo-sourced steering wheel and shift knob. Its engine bay features a 266 hp (198 kW) 7M-GTEU. It is important to note, that the 7M-GTEU was standard in all Japanese spec delivered MA70’s, the 7M-GTEU was not unique to the Turbo-A. The “U” designation meant the engine came equipped with a catalytic converter as per Japan-spec emissions.
All Group-A race cars were fitted with a TRD-sourced torque-vectoring mechanical limited-slip differential with 50:50 left:right lockup on full throttle. TRD was also responsible for the thick rear-anti squat tram-rods which was integral to the multi-link rear suspension setup to control rear squat under hard acceleration and launching.
It made the maiden voyage straight out of port and drove home 100% no problem. These are OUR cars!
