A 3.0 liter, six-cylinder engine known as the 2JZ-GE powers the Lexus IS300. Fans of the MkIV Supra ought to be acquainted with its engine code. Although it had a few internal tweaks and no turbos, the engine was fundamentally the same as the one in the Toyota Supra. An engine that, incidentally, the JDM Altezza never provided.
The Lexus IS300 produces 215 horsepower and 218 lb-ft less power than the Supra without turbos (alone). That is, at least, the stock production. Owners frequently install Supra turbos on their Lexus IS300s. According to Jalopnik, the 2JZ’s iconic status is directly related to how overbuilt it was. The Bubble Era, which gave the world the Skyline GT-R and Autozam AZ-1, came to a close at this time. According to Jalopnik, owners could theoretically triple the IS300’s output without any problems with the right tune.
Additionally, according to MT, there were the TRD-tuned Lexus IS300 L-Tuned versions. Stage I automobiles have a body kit, fog lamps, and an 8 horsepower stainless steel exhaust. New springs, bigger anti-roll bars, cast-aluminum wheels, and Michelin Pilot Sport tires are added to Stage II versions. They ride one lower as well. Additionally, a limited-slip rear differential was a choice.

Which Lexus vehicles feature the 2JZ?
Given the possibilities of the inline-six, it is not surprise that Alberth seemed to adore the 2JZ engine. The Lexus IS300 has a 2JZ engine as standard equipment, but it’s the naturally aspirated model, which has unique pistons and a unique head. Even more astonishing is Alberth’s continued usage of the stock 2JZ GE head, despite Porting Solutions’ porting work on it.
As far as other high-horsepower 2JZ builds go, the majority of the other parts are very common. Similar to Alberth’s 204SX, which in his opinion, has a redesigned intake, a 105 mm throttle body, 12 injectors (two per cylinder), and an 86-85 Precision turbo, the IS300 had these features as well “appears to be the preferred turbo for this engine. In contrast to the Nissan, the IS300’s engine has been expanded to 3.2 liters. All of it is controlled by a Haltec Elite 2500 ECU. The crucial information is shown on a Haltec IC7 instrument cluster.
Alberth notes that it’s interesting that the Manley pistons and connecting rods are Honda-spec, not Toyota-spec. The entire configuration is beneficial to “A 4L80 automatic transmission with the option for manual changing at the steering wheel transmits more than 1,200 horsepower to all four wheels. Eventually, Alberth divulges certain performance data, such as the 2.89-second sprint from 60 to 130 mph (97 to 210 km/h).
How many Lexus IS300s have a 2JZ engine?
Every IS300 produced between 1998 and 2003 has a 2JZ motor. This engine is a 2JZ-GE, which is the same as the one in a Toyota Supra. The IS300 has become a favorite among those who enjoy customizing Japanese automobiles because they are renowned for producing a lot of power when modified.
In the IS300, the 2JZ standard engine developed 217 horsepower and 218 pound-feet of torque. Depending on the arrangement, this was mated to either a 5-speed automatic or 5-speed manual transmission. The SportCross wagon was initially solely offered with the automatic, but over time, third-party retailers have started to replace them with the manual.
Due to its Supra-like engine, available manual transmission, and rear-wheel drive, the first generation IS300 is a renowned little sports sedan. These elements work together to make the IS300 a fantastic, entertaining sports sedan.
The Lexus IS300 is a 2JZ.
The larger Lexus GS300 sedan’s 2JZ-GE 3.0-liter DOHC 24-valve straight-six, which may be traced back to the previous Toyota Supra, is the same engine that powers the IS300.
Are there 2JZ engines in Lexus GS300s?
The Lexus GS300’s factory-installed engine is a NA Toyota 2JZ-GE, but an upgrade to the venerable 2JZ-GTE like this produces significant power.

What exactly does 2JZ mean?
The remaining letters in the 2JZ-engine GTE’s code are “JZ” (simply the engine family), “G” (performance-oriented dual overhead cam configuration), “T” (turbocharged), and “E” (electronic fuel injection).
What vehicles featured the 2JZ GTE?
Your suspicion is right if you’re asking whether the 2JZ engine has ever been used in America. The only 2JZ vehicle sold in the United States, however, lasted for just five years, from 1993 to 1998. T stands for induction through force, and the vehicle was the recognizable Supra Twin Turbo.
The vehicle had a 3.0L engine and could produce 320 horsepower at 5,600 rpm. The same had torque figures of 315 lb-ft at 4,000 rpm. For a car from the 1990s, the 100 km/h mark was reached in 5.6 seconds, which is very impressive. The automobile was incredibly quick for its era, reaching 155 mph at its top speed.
What Lexus model has a 1JZ?
This 2002 Lexus IS300 had mismatched bodywork, some off-road scars, and an ambitious new owner with a head full of ideas before it was powered by Toyota’s venerable workhorse 1JZ and before it appeared tidy enough to win a few awards at a local car show.
What does a 2JZ cost?
A race-ready 2JZ-GE engine typically costs $50,000 to construct. This special engine is utilized just in racing and is capable of producing 500 horsepower.
All of this is to suggest that these are pricey engines designed for race vehicles rather than the recreational driver.

How quickly can an IS300 travel?
A great accomplishment is the 143 mph top speed of the 2021 Lexus IS 300. Although motorists should travel at safe speeds when using public roads, this peak speed number is sure to delight driving aficionados.
Is IS300 quick?
But goodness, those powertrainssome of which have remained in use since the late 2000sneed to schedule an appointment with the great bench dyno in the sky. The 3.5-liter V-6 engine in the 2021 IS300 AWD we drove sends power through a six-speed automatic transmission and onto an all-wheel-drive system, making it one of the strangest and most antiquated options available within the IS line. In an effort to match the regular rear-wheel-drive IS300’s 2.0-liter turbocharged I-4’s 241 horsepower and 258 lb-ft of torque, the engine’s output has been drastically reduced from the IS350’s 311 horsepower and 280 lb-ft to a lower 260 horsepower and 236 lb-ft.
Crazy, huh? According to Lexus, it was more economical to simply reduce the 3.5-liter’s output than to change the AWD system to match the 2.0-liter. Even worse, the IS300 AWD’s performance was barely slowed by the removal of 51 horsepower and 34 lb-ft of torque from the eight-speed IS350, which has greater power. The IS300 AWD matched the rear-wheel-drive 2021 IS350 F Sport to 60 mph but lost the dragstrip sprint by 0.1 second, zipping from 0 to 60 mph in 5.7 seconds and covering the quarter-mile in 14.3 seconds. Say what?
Can a 2JZ GE be turboed?
When it comes to turbocharging a 2JZ-GE engine, there are numerous possibilities. For a 2JZ, turbo kit options are the least expensive and most practical way to implement forced induction. If achieving large power goals is the ultimate goal, some people choose a custom arrangement. We will be mostly focused on pre-made kits to avoid misunderstanding as custom turbo setups are very specialized and specific to each individual automobile.
The 2JZ-GE is available with a large selection of turbo kits, just like the majority of highly customizable engines. Choosing the ideal turbo kit for your unique needs necessitates taking many things into account. What budget have you set out for a kit? What kind of power are you seeking? What auxiliary modifications are necessary to run each kit?
Fortunately for you, we’ll examine a couple of the most popular 2JZ-GE turbo conversion kits and go through their advantages and disadvantages.
Are 2JZ engines reliable?
The 2JZ engine, a storied engine in the tuner scene, is what gave the last year of the Supra its enormous popularity. The closed, over-engineered engine design enables the utilization of significant boost on internals that are already in place. The 2JZ can survive a lot of punishment because to this plus the inherent durability of any inline-six engine architecture, but the best way to really appreciate how Toyota created the 2JZ to be so resilient is to go inside one.
Stephan Papadakis, owner of the wildly successful Formula DRIFT team Papadakis Racing, dissects the 2JZ engine and explains how it functions in order to examine the design.
The twin-turbo 2JZ engine was not unique to the Supra, despite it having gained popularity because to it. Toyota also employed a variation in the Aristo, a vehicle that underwent a US rebranding to become the Lexus GS. The variation Papadakis examines on screen makes use of variable camshaft timing on the intake.
There is a fairly definite take down order to it, even though a large portion of the disassembly is very much identical to disassembling any engine. The advantages of the powerhouse are evident in almost every component, working inward from the outside.
Four valves per cylinder are made possible by the dual overhead cams, which also permit a top plug design for the best spark and a superior air/fuel mixture and flow. Although this prevents the use of really aggressive cams, bucket style lifters sit on the camshaft lobes, which decreases the number of moving parts in the engine and improves reliability.
Toyota employed a multi-layered steel head gasket for this engine, which lowers the likelihood that it may blow, and a closed-block design, which supports the cylinder walls. Toyota attached a girdle to the underside of the 2JZ to increase the block’s stiffness while still allowing access to the rotating assembly. The rotating assembly is finally made practically indestructible by a forged crankshaft, a wide bearing design, and a lot of thrust bearing. It is not at all unexpected that this engine has been so successful with the tuner community.
How many HP can a 2JZ GE produce?
Toyota’s Supra can be traced back to the late 1970s, when the brand split off as a little beefier version of the company’s Celica coupe. Wheelbases on Celica Supras were longer, they were wider, and their six-cylinder engines were more potent. However, they remained Celicas.
When the fourth generation model was released in late 1992, the Supra had shed the Celica from its moniker and now shared about as many connections with the company’s entry-level sport compact as it had with the tacky little Paseo. The MkIV Supra’s factory turbocharged 2JZ-GTE powerplant, an inline-six cylinder engine so ready to make sobering sorts of horsepower that, even 28 years later, pro motorsports teams of all kinds still seek out the early ’90s 3.0L just as they did decades prior, was largely responsible for all of that. And with good cause. The 2JZ-GTE is capable of producing the kind of absurd horsepower that few production engines before or subsequently have been able to do with so few changes.
Where To Find One
- The 2JZ-GTE was first released in Japan in 1991 under the hood of the Toyota Aristo and continued to run in a few Japanese Supras until 2002, when the car was completely phased out.
- The 2JZ-GE, a naturally aspirated older brother that is more accessible and built on the same short-block and almost similar but higher-compression rotating assembly as the 2JZ-GTE, is only capable of producing roughly 230 horsepower, according to Toyota. These don’t concern you. Avoid them by avoiding peering behind the hoods of Lexus IS300, GS300, and SC300, as well as non-turbo fourth generation Supras.
- Here in the US, the 2JZ-GTE was only offered in Supra Turbo models from 1993 to 1998. It was a brand-new design that was entirely independent of the 7M-GTE from the previous Supra.
