1979-2002 Toyota Supra

Features

With the fourth generation of the Supra, Toyota took a big leap in the direction of a more super sports car. The new Supra was redesigned from the ground up and featured two completely new engines: naturally aspirated 2JZ-GE 220 hp (164 kW) and 210 ft·lbf (285 N·m) of torque, or a twin turbocharged 2JZ-GTE making a whopping 320 hp (239 kW), 315 ft·lbf (427 N·m) of torque. The turbocharged variant could achieve 0-60 in 4.6 seconds and 1/4 mile (402 m) in just under 13.1 seconds at over 109 mph (175 km/h). The stock turbos are capable of running around 400 bhp (298 kW) with an unrestricted airflow/exhaust system and an aftermarket boost controller (commonly known as a BPU setup).

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.

MKIV Supras have been modified (larger turbos running 30+ psi (206 kPa) of boost and other, undisclosed tweaks) to produce over 1200 hp (985 kW) and run the 1/4 mile (402 m) in 7.9 seconds. The stock engines are astonishingly tough, running 600bhp+ (447 kW) as daily drivers without having to update any internal components.

In 1998, Toyota ceased to export the cars from Japan, and they stopped production altogether in 2002 due to a decline in sales.

The Toyota Supra offers a bold mix of world-class performance, outrageous styling and luxurious comfort unmatched by any other vehicle in its class. Engine modifications for normally aspirated models highlight the 1998 Supra line. In response to ever-increasing emission requirements, and for the first time in a Toyota-nameplate vehicle in the U.S., all normally aspirated models are fitted with Toyota’s Variable Valve Timing with intelligence (WT-i). Designed to enhance engine performance while improving fuel economy and vehicle emissions, WT-i employs continuously variable intake valve timing control to provide greater engine performance, better fuel economy and reduced emissions over a broad rpm range. Fitted with WT-i, Supra’s 3.0-liter, 24-valve, inline six-cylinder engine produces 225 horsepower at 6,000 rpm, an increase of five horsepower over the previous year’s model (and up 200 rpm from last year). Torque is increased as well, to 220 lb.lft. at 4,000 rpm, an increase of 10 (and occurring 800 rpm sooner than last year’s model). Normally aspirated 1998 Supras are available only with a four-speed electronically controlled automatic transmission.

SUPRA TURBO

Supra Turbo models utilize fixed valve timing and twin sequential turbochargers to produce 320 horsepower at 5,600 rpm and 315 lb./ft. of torque at 4,000 rpm. During low-rpm operation, only one turbo operates while using less exhaust energy to improve response and torque when accelerating. In the middle rpm range, the second turbo comes to idle speed at a pre-set exhaust pressure for a smooth transition from the primary to the secondary turbo. Both turbos operate at full boost in the high rpm range. Supra Turbo is available with a choice of transmissions: either a four-speed electronically controlled automatic transmission with manual-shift mode or a six-speed manual. The automatic has an integrated manual shift mode and can be used as a clutchless manual providing faster shift times than in its fully automatic setting. The manual transmission is available only in those states that do not require California emissions.

STANDARD FEATURES

Supra combines its impressive power with responsive steering and suspension. A limited slip differential is standard on all models in 1998, ensuring that wheel slippage is minimized under all driving conditions. Turbo models are fitted with a Torsen™ torque-sensing limited-slip differential, while normally aspirated models use a conventional clutch-pack type. Turbo models also feature an on/off traction control system with an integrated "snow" mode. Vehicle-speed sensing power-assisted rack-and-pinion steering allows Supra to be responsive to driver controls at high speeds while remaining easy to park in town. A double-wishbone four-wheel independent suspension ensures a smooth ride and accurate vehicle control. On Turbo models, the suspension is tuned to take advantage of the vehicle’s performance potential, without sacrificing a comfortable ride. Brakes are four-wheel disc on all models. A four-channel, four-sensor (threesensor on normally aspirated models) anti-lock brake system with lateral g-sensor also is standard. Passive safety features include dual SRS airbags, side-door impact beams, three-point front and rear seat belts with an ALR/ELR feature in the front passenger and rear positions, and a high-performance head lamp system with integrated fog lamps. Supra is as exciting to look at as it is fun to drive. A rear spoiler is standard on all Sport Roof models. Color-keyed bumpers, dual color-keyed power-operated outside mirrors and green solar energy-absorbing glass also are standard on all models. Non-turbo models come equipped with 225/50R16 92V tires on the front and 245/45R16 94V on the rear. Turbo models feature 235/45ZR17 performance fires on the front and 255/40ZR17 on the rear.

Supra enters 1998 with two new exterior colors — Quicksilver and Imperial Jade Mrca. Interiors are available in coordinating Ivory or Black in either leather or an improved-grade fabric. Sport Roof models are equipped with a Premium AM/FM/ETR/Cassette/CD with seven speakers as standard equipment, while normally aspirated hard-top models are equipped with a Premium AM/FM/ETR/CD with six speakers. All Toyota radios for the 1998 model year receive redesigned faceplates. The cockpit-style interior features a wrap-around dashboard, a new three-spoke steering wheel, and specially contoured sport seats designed to fit all drivers and passengers. Additional amenities include power windows and door locks (with a retained power feature), cruise control, automatic air conditioning, anti-theft system, leather-wrapped tilt steering wheel and shift knob, heavy duty rear defogger and autooff head lamps. All Turbo models include power seats and leather seating surfaces as standard.

Toyota’s 36-month/36,000 mile comprehensive new-vehicle limited warranty applies to all components other than normal wear and maintenance items. Additional 60-month limited warranties cover powertrain components for 60,000 miles and corrosion perforation with no mileage limitation. Toyota dealers have complete details on the limited warranty.
