The 1993 Mark IV Toyota Supra 2JZ was a very popular sports car that Toyota made, complete with a powerful engine and easily (and heavily modified) turbochargers. A lot of modified Supras can be seen on the road today, and they were quite popular among enthusiasts and gearheads who liked to upgrade their vehicles.
It came from Japan in 1993 as part of the ‘muscle car’ genre, and it remained in production until the late 20th century and early 21st century.
Read on to find out more popular perks and quirks of the 1993 Mark IV Toyota Supra 2JZ.
This model of Supra swapped out a lot of heavier materials in favor of lighter ones. Weight reduction was the endgame here, and it shows. The previous model was much heavier, so Toyota decided to reduce as much weight as possible at a time where lightweight supercars reigned supreme. Weight reduction would thereby give Toyota a chance against their competition.
In the end, the Mark IV was 100 pounds lighter than its predecessor, largely thanks to the use of plastic where applicable, a magnesium steering wheel, and a lot of aluminum placed throughout the exterior chassis, such as the hood. Aluminum was also seen in the Targa top, front cross member, oil pan, and upper A-arms. The rear spoiler was also gas-injected.
The lighter materials and overall lighter weight allowed Toyota to tack on additional features without significantly compromising weight, such as traction control, larger brakes, dual airbags, larger wheels, and larger tires.
Engine Power Is Key
This particular model of Supra achieved popularly mainly because of its powerful engine. The 2JZ-GTE inline-six of the Mark IV Toyota Supra had its two sequential turbochargers, which, for 1993, was quite notable.
Two different engine options were available for the Mark IV Toyota Supra. Drivers could choose either a naturally aspirated 2JZ-GE, 3-liter straight 6 that could put out 220 horsepower and 210 ft/lbs of torque, or they could go with a 2JZ-GTE 3-liter twin-turbocharged straight 6 that could put out 320 horsepower and 315 ft/lbs of torque. Said turbochargers operate in a sequential format, redirecting all exhaust gases to the first turbine for a reduced lag in order to achieve a reduced boost and enhanced torque.
The exhaust gases then continue their journey, heading to the second turbine to let both turbochargers operate in tandem and generate a superior low-end response. The Mark IV Toyota Supra continued to garner public attention with more power output available, as its turbochargers could be modified via an aftermarket boost controller to put out 450 – 500 horsepower.
After all, it was relatively common to see Supras modified with aftermarket parts having engines that could put out 1000 horsepower (or more) with ease. With this ability on deck, the Supra became much more than what was seen at face value; it had sudden worth in the eyes of car enthusiasts, as well as a place in the first Fast and Furious movie.
The engine itself is also furiously strong, thanks to the use of a cast-iron block. And because the engine is a closed deck, the cylinders themselves become strong enough to handle massive amounts of turbo air pressure, as large reserves of air can be successfully pushed through said cylinders without the core of the engine becoming a concern.
Finally, its three-layer steel head gasket was designed well enough to withstand high boost pressure, and its forged steel crankshaft serves its purpose in reinforcement. With the Mark IV Supra, Toyota turned a gas-powered sports car engine into something strong enough to compete with a high-compression turbo-diesel truck engine.
Perks and Quirks
A lot of other features of this Supra were notable for their rarity or impracticality. The higher-end models were rare when new because they were expensive. As of 2021, they are still expensive. Prepare for a massive clink when shifting from reverse into first gear. Whining under power is also common, and drivers have noticed how most of the Supra’s features are as over-engineered as the engine is.
Further, with modifications available, any car enthusiast can become an overnight gearhead; however, not all of them have the knowledge of mechanics, so a lot of shortcuts were taken. As the Supra was notable for its modification capabilities, a lot of experimentation went into this vehicle to the point where modified Supras are seen roaming the streets than unmodified Supras are.
Export Has Differences
The home model from Japan and the model exported overseas have some significant differences. The export version was more highly specified than the Japanese (home) model, which is an inversion of the usual scenario.
As a result, the export versions were fitted with stronger steel turbos, bigger fuel injectors, glass headlights, bigger brakes, and a full-leather interior. The aforementioned over-engineered version of the Supra was the export version, so it didn’t need vital internal parts upgraded for modification purposes.
Therefore, the export models, particularly in the American market, had more power due to larger stock injectors and bigger turbochargers than the Japanese versions would have. The catch was that the American version of the Supra was the second to be taken off the market, departing in 1998, following the Canadian version’s departure in 1996. The Japanese versions, however, would remain until 2002.
