| The Toyota
Supra JZA70 was released in mid 1990 and was fitted with the first
generation of the JZ engine series, the 1JZ-GTE. Rated at 206kw,
this pushed the Supra (*TwinTurbo R) to a mid 14 second
quarter mile time, 1 second quicker than the MA70 Turbo.
There were several specs of JZA70,
ranging from the packed out luxury model (x) to the sports model
(TwinTurbo R). The
TwinTurbo R came factory with Recaro seats, steering wheel and
shifter knob and matching trim panels, it also came fitted with
Bilstein shock absorbers with up rated springs and charcoal 5 spoke
alloys.
Other features of the JZA70 Supra was
the replacement of the mechanical clutch LSD with a Torsen unit. The
final ratio was also changed to 4.11 compared to the 3.73 of the
MA70.
