Toyota Supra

supra-twin-turboThe Super Supra, twin turbo of 2JZ power, awesome looking car which looks even better a cool kit. In standard form the twin turbo could get to 60mph in around 4.6 seconds and stomping on to over 175mph.

Toyota took a big leap in the direction of a more serious high-performance car. Again using subframe, suspension and drivetrain assemblies from the Z30 Soarer (Lexus SC300/400), test model pre-production started in December 1992 with 20 models, and official mass production began in April 1993.The new Supra was completely redesigned, with rounded body styling and featured two new engines: a naturally aspirated Toyota 2JZ-GE producing 220 hp at 5800 rpm and 210 lb·ft at 4800 rpm of torque and a twin turbocharged Toyota 2JZ-GTE making 276 hp and 318 lb·ft of torque for the Japanese version. The styling, while modern, does seem to borrow some elements from Toyota’s first grand touring sports car, the Toyota 2000GT. For the export model (America/Europe) Toyota upgraded the Supra turbo’s engine (smaller, steel wheeled turbochargers, bigger fuel injectors, etc.). This increased the power output to 320 hp at 5600 rpm and 315 lb·ft at 4000 rpm. The turbocharged variant could achieve 0–60 mph in as low as 4.6 seconds and 1/4 mile (402 m) in 13.1 seconds at 109 mph. The turbo version was tested to reach over 177 mph all-stock, but the cars are restricted to just 112 mph in Japan and 155 mph elsewhere. European versions of the car also had an air intake on the hood. Drag coefficient is .31 for the naturally aspirated models and .32 for the turbo models but unknown with the rear spoiler.

The Mark IV Supra’s twin turbos operated in sequential mode, not parallel. Initially, all of the exhaust is routed to the first turbine for reduced lag. This resulted in boost and enhanced torque as early as 1800 rpm, where it already had 300 lb·ft of torque. At 3500 rpm, some of the exhaust is routed to the second turbine for a “pre-boost” mode, although none of the compressor output is used by the engine at this point. At 4000 rpm, the second turbo’s output is used to augment the first turbo’s output. Compared to the parallel mode, sequential mode turbos provide quicker low RPM response and increased high RPM boost. This high RPM boost was also aided with technology originally present in the 7M-GE in the form of the Acoustic Control Induction System (ACIS) which is a way of managing the air compression pulses within the intake piping as to increase power.

For this generation, the Supra received a new 6-speed Getrag/Toyota V160 gearbox on the turbo models while the naturally aspirated models made do with a 5-speed manual W58, revised from the previous version. Each model was offered with a 4-speed automatic with manual shifting mode. Turbo models were equipped with larger brakes and tires than naturally aspirated models. All vehicles were equipped with 5-spoke aluminium alloy wheels and a space saver spare tire on a steel wheel to save weight and space.

Is this rear wheel drive hybrid sports car the successor to the Supra? It can do 0-60 in around 4 seconds and is powered by a 3.5 litre V6 and an electric motor.
