MKIV Supra

The MKIV Supra’s twin turbos actually operated in sequential mode instead of parallel mode as the "twin turbo" name usually implies. The way that the sequential mode operated was the first turbo starts spooling at low rpms & as the rpms increased, the second turbo joins in. This helped in reducing turbo lag. Most cars which are advertised as "twin turbo" operate by having the two equally sized turbos constantly running in parallel; the turbos spool up at the same time. For this generation, the Supra received a new 6-speed Getrag transmission on the Turbo models

 The Japanese twin turbo uses ceramic (exhaust side only) shafts which can be replaced with no modifications by the steel CT20A (large version) turbine shafts. These steel shafts are found in 2JZ-GTE Aristo's and some turbo diesel Toyotas.

POWERTRAIN OPTIONS AND AVAILABILITY

Two 3.0-liter inline 6-cylinder engines have been available, each with dual overhead camshafts. A normally aspirated engine went into base Supras, producing 220 horsepower. Turbos employed a twin-turbocharger version, putting out 320 horsepower and 315 pound-feet of torque. Base Supras had a standard 5-speed manual gearbox; Turbos, a 6-speed. Either might be equipped instead with a 4-speed automatic transmission.

The fourth-generation Toyota Supra remained relatively unchanged throughout its lifespan. The base trim level came with a 3.0-liter 24-valve inline-6 engine that generated 220 horsepower and 215 pound-feet of torque. It was offered with either a five-speed manual or a four-speed automatic. More impressive was the Supra Turbo. Powered by a sequential twin-turbocharged 3.0-liter 24-valve inline-6, the Turbo produced 320 hp and 315 lb-ft of torque. Zero-to-60 times were in the low 5-second range. For the first time, the Supra looked and drove like an exotic performance car. And it came loaded with a number of standard features that were impressive for the day, including traction control, a limited-slip differential, 17-inch aluminum alloy wheels, a sport-tuned suspension and a six-speed manual transmission.
