Basics
Attractive curves and a long wheelbase do little to prepare an observer for what lies beneath the hood of the MKIV Supra. A complete redesign from the previous generation, Toyota's designers looked to the then-fastest street-legal production car in the world for a muse — the Ferrari F40. Conceived as a Ferrari fighter from day one, the MKIV Supra lived up to the promise its name made to "go beyond."
Designated the JZA8x platform, the new Supra measured up as follows:
| Dimension | Imperial | Metric |
|---|---|---|
| Wheelbase | 100.4 in | 2550 mm |
| Length | 177.8 in | 4515 mm |
| Width | 71.3 in | 1812 mm |
| Height | 49.8 in | 1265 mm |
| Curb weight — 2JZ-GE | 3210 lb | 1460 kg |
| Targa roof add / automatic add (2JZ-GE) | +40 lb / +55 lb | |
| Curb weight — 2JZ-GTE | 3505 lb | 1581 kg |
| Targa roof add / automatic add (2JZ-GTE) | +40 lb / +10 lb | |
| Fuel capacity | 18.5 USG | 70.0 L |
Despite its well-equipped nature the MKIV Supra still weighed less than both the Nissan R33 and R34 Skyline GT-Rs as well as the Mitsubishi 3000GT VR4. And despite its larger overall dimensions it came in at approximately the same kerb weight as the smaller Nissan Fairlady Z.
Design
Built at the Motomachi Plant in Toyota City, Japan, the MKIV came in at 200 lb lighter than the MKIII it replaced, yet still incorporated a full range of updated safety and performance features along with a drag coefficient of 0.33. Standard equipment included dual airbags, traction control, larger brakes, larger wheels and tyres, and a second turbocharger.
Weight savings were achieved through race-bred engineering: dished head bolts, a plastic fuel tank and lid, a gas-injected rear spoiler, single-pipe exhaust, hollow carpet fibres, and a magnesium steering wheel. Aluminium construction was integrated throughout — hood, front cross-member, upper suspension A-arms, oil and transmission pans, and the targa top on equipped models.
Drivetrain
2JZ-GE (Naturally Aspirated)
The naturally aspirated 2JZ-GE is often overlooked in favour of its turbocharged sibling, but the inline-six still produced 220 hp at 5800 rpm and 210 ft·lbf of torque at 4800 rpm from 3.0 litres of displacement — more than any R32 or R33 Skyline model outside the GT-R, and delivered without any turbo lag to speak of.
The 2JZ-GE used SEFI fuel injection with 4 valves per cylinder (32 total) and an aluminium head. The same engine was also found in the Toyota Crown and Toyota Mark II. Also found in models of the Toyota Crown and Toyota Mark II, the 2JZ-GE made for a capable and refined everyday driver.
2JZ-GTE (Twin Turbo)
Built under the pretence of homologation for the Japanese Grand Touring Car Championship (JGTC), Toyota outsourced engineering of the 2JZ-GTE to German firm Johann A. Krause Maschinenfabrik GmbH. The result — sequential twin CT12B turbochargers and an intercooler — became the star of Toyota's JZ engine family.
The Japanese-market 2JZ-GTE was officially rated at the domestic regulatory ceiling of 276 hp at 5600 rpm and 260 ft·lbf of torque at 4000 rpm. Real-world output was widely understood to be well above 300 hp in stock form.
At the limit, stock 2JZ-GTE Supras recorded 0–60 mph in as little as 4.6 seconds and a quarter-mile in 13.1 seconds at 109 mph. They were also known to be capable of 180 mph, though the JDM cars were electronically restricted to 180 km/h.
JDM vs. Export Engine Comparison
For North American and European markets, official power output was raised to 320 hp at 5600 rpm. The two versions differed mechanically as follows:
Japan
- CT12B turbos with ceramic turbine blades *
- 440 cc/min fuel injectors
- Differing camshaft specification
North America and Europe
- CT20A turbos with stainless steel turbine blades *
- 550 cc/min fuel injectors
- Differing camshaft specification
* The ceramic shaft of the CT12B can be replaced with the harder-wearing steel shaft from the CT20A.
Beyond the turbo differences, the 2JZ-GTE's durability set it apart. Both the crankshaft and connecting rods were forged from the factory — only the pistons were cast. This commitment to quality is why the engine achieved legendary status in the tuning world, with numerous examples producing quadruple-digit horsepower on completely stock internals. In the tuning market this engine was considered the primary competition to the Nissan RB26DETT found in the R32 Skyline GT-R.
How the Sequential Twin-Turbo System Works
Traditional parallel twin-turbo setups do nothing to reduce the lag created by routing exhaust through two turbines simultaneously. The 2JZ-GTE's sequential arrangement addressed this directly, producing usable power earlier and with more linearity across the rev range.
- Idle to ~3800 rpm: All exhaust gas flows through the first turbo. Boost builds from as low as 1800 rpm, greatly reducing lag.
- ~4000 rpm: Exhaust begins to split toward the second turbo, which enters a pre-spool stage — blades spinning but not yet contributing boost.
- ~4500 rpm: Exhaust divides evenly between both turbos as they approach full spool together.
The trade-off is complexity. Sequential systems are less familiar to tuners than parallel setups, making very large power builds more difficult to execute. For drag-strip-only use, a single or parallel turbo conversion is more practical. For autocross and road racing, the sequential system's linear power delivery is a distinct advantage.
Transmission
The 2JZ-GTE models received a 6-speed Getrag/Toyota V160 manual gearbox. The 2JZ-GE was paired with a 5-speed Toyota W58. Gear ratios were as follows:
6-Speed Manual (V160)
- 1st: 3.830:1
- 2nd: 2.360:1
- 3rd: 1.680:1
- 4th: 1.310:1
- 5th: 1.000:1
- 6th: 0.790:1
5-Speed Manual (W58)
- 1st: 3.285:1
- 2nd: 1.894:1
- 3rd: 1.275:1
- 4th: 1.000:1
- 5th: 0.783:1
- Reverse: 3.768:1
Both engine variants were also available with a 4-speed "manumatic" automatic (A341E). Some reports noted quirks in reverse engagement and hesitation through the positive gears — characteristics typical of the torque-converter behaviour in sport-shift automatics of that era rather than true faults.
Brakes, Wheels, and Handling
The 2JZ-GTE models used 4-piston front calipers and 2-piston rear calipers, mounted over 17-inch 5-spoke aluminium alloy wheels. Tyre sizes were 235/45/17 front and 255/40/17 rear. The 2JZ-GE was equipped with 2-piston front and single-piston rear calipers on 16-inch wheels, with 225/50/16 front and 245/50/16 rear tyres.
Weight distribution was well-balanced: the 2JZ-GE split 51/49 front-to-rear; the heavier 2JZ-GTE came in at 53/47. In 1994 testing, the 2JZ-GTE recorded a skidpad figure of 0.98 lateral g — remarkable for a car of its weight. That same year it posted a 70–0 mph braking distance of 149 feet, the best braking performance of any production car tested by Car and Driver in 1997.
This performance was enabled by a 4-sensor, 4-channel ABS system with yaw control. Sensors at each caliper allowed the system to modulate braking force individually based on angle, speed, and pitch.
Closing Thoughts
The MKIV Supra was technically ahead of its time from both an engineering and performance standpoint. Few production cars of its era approached the performance-to-price ratio that the 2JZ-GTE Supra delivered — and fewer still have aged as well. Power, balance, and style rarely come together as cleanly as they did in this generation.
