Toyota Supra Mk3 History

Toyota Supra Mk3 ...

In May 1986, Toyota was ready to release its next version of the Supra. The bonds between the Celica and the Supra were cut; they were now two completely different models. The Celica changed to front-wheel drive, utilizing the Toyota "T" platform associated with the Toyota Corona, while the Supra kept its rear-wheel-drive platform. The engine was updated to a more powerful 3.0 200 hp (149 kW) inline 6. Although only available in naturally aspirated trim in 1986.5, a turbocharged version of the engine was introduced in the 1987 model year. The Supra was now related mechanically to the Toyota Soarer for the Japanese market.

All Japanese market Supras with the various versions of the 2.0 L engine were installed in a vehicle that was slightly narrower on the outside so as to be in compliance with Japanese Government dimension regulations so that Japanese buyers weren't liable for yearly taxes for driving a larger car.

The Supra also traces much of its roots back to the Toyota 2000GT with the main instance being its engine[citation needed]. The first three generations were offered with a direct descendant to the Toyota Crown's and 2000GT's M engine. All four generations of Supra produced have an inline 6-cylinder engine. Interior aspects were also similar, as was the chassis code "A"

Along with this name and car Toyota also included its own logo for the Supra[citation needed]. It is derived from the original Celica logo, being blue instead of orange[citation needed]. This logo was used until January 1986, when the A70 Supra was introduced. The new logo was similar in size, with orange writing on a red background, but without the dragon design. That logo, in turn, was on Supras until 1991 when Toyota switched to its current oval company logo. (the dragon logo was a Celica logo regardless of what color it was. It appeared on the first two generations of the Supra because they were officially Toyota Celicas. The dragon logo was used for the Celica line until it too was discontinued.)

In 1998, Toyota ceased sales of the Supra in the United States[3] and in 2002 Toyota officially stopped production of the Supra in Japan

Generation names are A40, A60, A70, A80. A Popular trend Started by American owners was to name the cars using Volkswagen Mark terms but this was never adopted by Toyota nor has ever been used in any of It's publications the "Official" names refer to the chassis codes only. Toyota uses, the name Mark II to refer to its X chassis platform cars that Include the Mark II, Cressida, Chaser and Cresta models.

The Supra has appeared in numerous video games, movies, music videos and TV shows[citation needed]. Some of the most notable appearances include the Gran Turismo, Forza Motorsport, Need for Speed, Midnight Club,and Forza Horizon 2 video games and The Fast and the Furious film series.[4][5]

The new A70 Supra engine, the Toyota 7M-GE, was the flagship engine of Toyota's arsenal. Both versions of the engine contained 4 valves per cylinder and dual overhead cams. The turbocharged 7M-GTE engine was Toyota's first distributor-less engine offered in the US which used coil packs sitting on the cam covers and a cam position sensor driven by the exhaust camshaft.[14] It was equipped with a CT26 turbocharger and was rated at 230 hp (172 kW) at 5600 rpm while the naturally aspirated 7M-GE engine was rated at 200 hp (149 kW) at 6000 rpm. Further refinement on the turbo model increased power to 232 hp (173 kW) and 254 lb·ft (344 N·m) in 1989. This was mostly due to a redesign of the wastegate. All models used the same tire size of 225/50R16 on 16x7 inch wheels. Spare tires were full-sized but on steel wheels.

Owing to a large error in the factory head bolt torque specifications (likely owing to switching away from using an asbestos head gasket in lieu of a copper one), all of these engines had severe problems with blown head gaskets. Toyota never issued a recall for any of the affected vehicles. The problem could be easily fixed by replacing the head gasket and torquing the head bolts to 75 lb·ft (102 N·m) of torque. However, owing to the lack of a recall or appropriate service bulletin, the head gasket problem would recur in another 75,000 miles or so if the gasket was replaced and the bolts were retorqued to the erroneous service manual specifications of 56 lb·ft (76 N·m). With the head bolts torqued correctly, the engines were otherwise extremely durable.

The naturally aspirated came as standard issue with the W58 manual transmission. The turbo versions included the more robust R154 manual transmission. Both were available with the optional 4-speed A340E automatic transmission.

The third-generation Supra represented a great deal of new technology. In 1986, options available for the Supra included 3-channel ABS and TEMS which gave the driver 2 settings which affected the damper rates; a third was automatically activated at WOT, hard braking, and high speed maneuvering. HKS also made a "TEMS Controller" to hack the system and activate it on the fly, though the controllers are now nearly impossible to find.

ACIS (Acoustic Control Induction System), a method of controlling air compression pulses inside the intake piping to increase power, was also a part of the 7M-GE's technological arsenal. All models were fitted with double wishbone suspension front and rear. A targa top was offered along with a metal power sliding sunroof (added in '91).

Total Supra A70's produced (GA70/MA70/JZA70): Estimated 241,471
