The Mark IV Toyota Supra was offered with two different engine options; a naturally aspirated 2JZ-GE, 3.0 litre, straight 6 with 220 horsepower and 210 ft/lbs of torque, and a 2JZ-GTE 3.0 litre twin turbocharged straight 6 with 320 horsepower and 315 ft/lbs of torque.
For many, part of the twin turbo Toyota Supra's attraction comes from the easily upgraded power output. 450 - 500 horsepower can be had out of the stock turbos with a free flowing intake and exhaust system coupled with an aftermarket boost controller.
