The 1993 Toyota Supra is powered by the renowned 2JZ-GTE high-performance, twin-cam, in-line six-cylinder, 24-valve, electronically fuel-injected engine. The Supra's twin turbocharged engine produces 320 hp at 5,600 rpm and 315 lb-ft of torque at 4,000 rpm. Supra's twin-sequential intercooled turbos provide quick response at low engine speeds and high-volume output at increased engine speeds. During low-speed operation, only one turbocharger operates, using less exhaust energy to improve response and torque from a standing start. In the middle-speed range, the second turbo comes to idle at a pre-set exhaust pressure for a smooth transition from the primary to the secondary turbocharger. Both turbos operate at full boost in the high-speed range. The transmission of choice is an equally strong six-speed manual transmission. The automatic's control system adjusts shift timing, lock-up timing, hydraulic pressure for the clutch and brake, and engine torque in order to deliver virtually seamless shifts. In manual mode, selected by a console button, the transmission shifts quickly into each gear as it is selected. Shift times in manual mode are quicker than in fully-automatic mode.
. Aluminum engine mounts also save weight. The Supra Turbo was not a lightweight by any means, tipping the scales at just over 3500 lbs.
Standard on Turbo models is a defeatable electronic traction control system which automatically senses wheel spin, limits power to prevent it and maintains traction.
The Supra Turbo has larger brakes front and rear than the standard Supra. Original tires for Supra Turbo are 235/45ZR17 in front, on 17x8-inch alloy wheels, and 255/40ZR17 in the rear on 17x9.5-inch alloys.
The Turbo model also has a limited-slip differential and traction control system, a specially tuned sport suspension, an engine oil cooler and a 100-ampere alternator.
The Turbo takes its time catching hold at low engine speeds; but when it does, the power surges into play dramatically. That can be annoying around town, actually--you get little power initially, but then an avalanche suddenly arrives as the twin turbos kick in.
Handling is top-notch on all Supras, with little body lean through turns and tenacious grip from the low-profile tires. On normal roads--smooth and dry--you get a secure, planted feeling as the suspension soaks up bumps fairly well.
At racing speeds, the Supra displays very little body roll when hurled into corners, and it sticks to the road like barnacles on a ship.
The Supra's extra-wide wheels reduce tire sidewall flex, which lends an exception-ally precise response to the Car's all-around handling. And big tires and big brakes add up to unusually strong stopping power. In this area, the Supra's performance may very well be the best in its class.
We were also impressed by the performance of our test Car's limited slip differential, which helped keep the rear wheels driving smoothly even in hard cornering and emergency avoidance maneuvers.
Back in its first test of the '93 Supra Turbo, "Car and Driver" ripped off a 13.1-second e.t. in the quarter mile at 109 mph and ripped from 0 to 60 in just 4.6 seconds
