“Two-jay-zee engine, no shit… This will abate all,” Jesse said in the aboriginal Fast and Furious cine afterwards criticizing the abominable junkyard-grade Toyota Supra that was aloof towed into the shop. In the easily of the appropriate tuners, annihilation is what the Supra was all about. Understanding why requires us to attending at conceivably the best allegorical tuner agent in history: the Toyota 2JZ-GTE.

We’re afraid with inline-sixes in this additional chapter of our new alternation “Engines You Should Know.” Except this time, instead of a artlessly aspirated, high-displacement, all-aluminum American motor, we’re attractive at a twin-turbocharged, iron-block, 3.0-liter overbuilt assertive from Japan.
The Toyota 2JZ-GTE came into this apple in 1991 during the aiguille of the Japanese balloon era, back that country’s auto industry, aerial on banknote and possibly added substances, was cranking out aggregate from agrarian mid-engined exotics to agrarian mid-engined microcars.
It was a aerial point for the Japanese auto industry, and the 2JZ was a high-point for big, tough, iron-block beeline sixes in commuter cars. There actually hasn’t been abundant like it since. The bazaar alone out for these cars and the money alone out for overbuilt agent projects in the ‘90s and hasn’t been filled, at atomic in Japan. Toyota alone puts big beeline sixes into trucks now, and its big rear-drive sedans accept V6s. Now, tuners accept gotten added engines in contempo years to accomplish as abundant ability as 2JZs, but they’re added rare, added big-ticket and they accept beneath aftermarket support. Any brace schmucks can bead a few thousand dollars to buy a 2JZ to charge into some old Nissan if they appetite to and accomplish a high-horsepower car in their garage.
The agent accustomed aloof afterwards Nissan absitively to addition the monster twin-turbo RB26DETT into its GT-R. But clashing Nissan, Toyota didn’t admission its athletic in a sports coupe; instead, the aggregation aboriginal showed the 2JZ-GTE in the four-door Toyota Aristo 3.0V (which we in the states apperceive as the Lexus GS) to homologate the auto for the Japanese Grand Touring Car Championship. Still, the 2JZ-GTE actually acquired its acclaim in Toyota’s aura car, the Supra.
The 2JZ-GTE is the arch of the JZ ancestors of inline sixes that launched in 1990 with the 1JZ-GE, a naturally-aspirated 2.5-liter inline-six that Toyota slapped into a cardinal of sedans, including the Chaser, Cresta, Acme and Mark II.
The 3.0-liter 2JZ-GE—a stroked adaptation of the 1JZ-GE—came anon thereafter, as did turbocharged and intercooled “GTE” variants of both agent generations. Those aerial achievement GTE models accustomed altered aluminum butt active with altered assimilation and bankrupt manifolds, higher-flowing injectors, recessed pistons alms lower compression ratios (which accustomed the engines to handle added boost), and oil squirters to accumulate the pistons cool.
Because of these differences, the GE models, which you can acquisition all day in Lexus GS300s, are not as adorable in the affability scene. But the 1JZ-GTE, whose acute internals aggregate about the aforementioned architecture as the 2JZ-GTE’s, is still awful accepted in the tuner community, alike if the lower displacement agency it doesn’t actually accept the monster ability potential.
The blow of the 2JZ-GTE’s agent cipher goes like this: “JZ” is aloof the agent family, “G” stands for performance-oriented bifold aerial cam setup, “T” stands for turbocharged and “E” agency its electronically ammunition injected.
Thanks to a “gentleman’s agreement” amid Japanese automakers at the time, the 2JZ-GTE was clearly rated at 280 application in its banal anatomy in the Aristo and JDM Supra. That was a audacious lie. And in the U.S.-spec A80 Supra—which launched for 1993 with bigger injectors, stronger turbos and altered cams—that cardinal went up to 320 application at 5,600 rpm.
Between the power, and the 315 pound-feet of torque at 4,000 rpm, the Supra instantly became a force to account with admitting its biggy weight (the agent itself advised over 500 pounds). The car could do aught to 60 mph in beneath bristles seconds, according to abreast tests, authoritative it a actual quick car in its day.
That was stock. Nobody kept the Supra stock. Way too abundant could be acquired if you messed with it.
From the factory, the 2JZ-GTE is already a appealing appropriate engine. It’s got bifold aerial camshafts, four valves per cylinder, a distributor-less agitation system, liquid-cooled consecutive turbos befitting the ability bandage nice and broad, and a “square” (one to one) bore-to-stroke arrangement that provided a abundant accommodation amid low-end balance and high-end power. Start affability it, though, and the agent goes from “special” to absolute supernatural.
The acumen why the 2JZ-GTE is so abounding in the affability arena is because of its strength. Its adamant block is boxy as nails, its seven capital bearings—despite alone actuality captivated by two bolts each—are actually gargantuan and authority the crankshaft firmly, its artificial 12-counterweight animate crankshaft can handle huge ability and aerial agent speeds, the oil pump and baptize pump can booty the abundant mods afterwards failure, the fully-closed accouter agency the agent can bear astronomic butt pressures, artificial abutting rods are stout, and the oil-cooled casting aluminum pistons can handle a assault as well.
This all agency you shouldn’t anguish about acceleration the 2JZ-GTE’s application via mods. In fact, best tuners accede the 2JZ-GTE’s basal end as able of arresting up to 800 ponies. Yes, 800 application on banal internals. And abounding tuners accept cranked endemic into the four-figure ambit with some added work.
Getting there isn’t actually that difficult, either. Admitting there are a brace big-bore and stroker kits out there, best high-horsepower 2JZ-GTEs get that balance by way of alteration out the assimilation and exhaust, swapping those consecutive turbos out for an astronomic distinct turbo (67mm is common), installing a bigger front-mount intercooler, and bolting on some bigger injectors and ammunition lines.
It was an avant-garde agent in its day, and for 1998, it became alike added so, as the Japanese adaptation got capricious valve timing. Sadly, the U.S. bazaar got nothing, and ’98 was the final archetypal year for the allegorical 2JZ-GTE in the U.S.
But admitting its abbreviate run here, the 2JZ-GTE charcoal a acme jewel in the tuner community, with Supras and 2JZ-swapped annihilation abroad always acceptable annoyance contest and whatever abroad they’re alleged to do.
Even 25 years afterwards its debut, the 2JZ-GTE continues to abate all.
