Toyota Supra Mark 3 Vehicle Information

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, while the Supra kept its rear-wheel-drive platform. Though the Mark II and Mark III had similar designs, 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, 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.



The new Mark III 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.



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 Nm) in 1989. This was mostly due to a redesign of the wastegate.
