What year was the Lexus 2JZ?
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.
Is there a 2JZ engine in the 1998 Lexus GS300?
The 2JZ generates 168 kW and 305 Nm of torque. Even after nearly 300,000 kilometers, the engine continues to run strongly. I doubt many people are aware that this automobile has a 2JZ engine (could be in my little imagination though). However, the automatic transmission in this vehicle makes thrashing the 2JZ boring.

What distinguishes a 2JZ GE from a 2JZ GTE engine?
The cylinder head designs of the 2JZ-GE and 2JZ-GTE are a significant distinction. Since forced induction was a consideration during the design of the 2JZ-GTE, certain significant alterations were made to the cylinder head to make it more boost-supportive.
Both versions of the 2JZ, as was already established, have aluminum heads with electronic fuel injection. However, as far as flow is concerned, each head is made with a certain goal in mind.
The 2JZ community as a whole agrees that the 2JZ-GTE head has superior flow on the intake side while the 2JZ-GE head has greater flow on the exhaust side. The 2JZ-wider GTE’s intake ports, which enable higher flow at higher RPMs, are to blame for the increased intake flow. This supports the performance of high-RPM turbos. The 2JZ-GTE has smaller exhaust ports than the GE, but having larger intake ports.
The 2JZ-GE, in contrast, has smaller intake ports that are intended to boost cylinder velocity at lower RPMs. In order to align for a more direct shot into the cylinder, the smaller ports are also positioned higher up on the head. This improves the efficiency of atmospheric pressure.
On the exhaust side of the head, the exhaust ports are placed differently on the two engines. The architecture of the 2JZ-GTE differs from the 2JZ-GE, which has all six exhaust ports aligned in a straight line. Exhaust ports on the 2JZ-GTE are set up in banks of three, with a space between the first and last three.
Which head flows better is a hotly contested topic since each has a specific function for the engine it was created for. It must be acknowledged, though, that the 2JZ-GTE has significantly greater aftermarket support for its intake and exhaust manifolds.
A Lexus 2JZ is it a 300?
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 far can a 2JZ travel?
There are several reasons why the fourth-generation Toyota Supra is legendary, but one of them is its dependability. The 3.0 liter 2JZ straight-six in this Supra, which has allegedly racked up 520,000 kilometers, is particularly bulletproof. The motor, according to the owner, has also “never been touched.”
The owner of the vehicle provided Hoover Toyota in Alabama with these photos. Although the Supra isn’t for sale, the dealer nonetheless posted images and details about the vehicle on Facebook.
Despite having 520,590 miles on the clock, the non-turbo Supra is said to be free of rust and to have undergone no significant engine work. Unfortunately, no other information is given, such as the year of manufacturing or other characteristics. This Supra only has 220 horsepower, which is 100 fewer than its turbocharged predecessor.
You can make fun of Toyota for producing a decent number of unremarkable, ordinary cars, but you must recognize that every product it produces is dependable. You can be sure it will last whether it’s a humdrum Camry, a 4Runner, or a Supra like this.
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 primarily focused on pre-made kits to avoid confusion as custom turbo setups are highly specialized and unique to each individual car.
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.

Along with its ride and handling, the GS’ interior comfort and quality also amaze. However, we didn’t care for the Remote Touch multimedia system, and the Mark Levinson sound that was an option.
What Lexus has a 1JZ engine?
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 2JZ engine is the best?
19 stars have been awarded to the 1JZ-GTE. 20 stars have been awarded to the 2JZ-GTE. The 2JZ-GTE comes out on top! Both engines are excellent; however, the 2JZ-GTE has certain advantages due to its displacement, while the 1JZ-GTE has advantages due to its somewhat lower price. Both engines are quite similar in terms of performance out of the box and tweaking possibilities. You’ll be on to a winner if you can get your hands on one of these engines.
With that said, a winner must be declared, so congratulations. 2JZ-GTE You *just* edged out your older brother for first place.

Which engine is superior, the 1JZ or 2JZ?
Contrary to popular assumption, the 1JZ and 2JZ are essentially equally powerful, which is a crucial point to make. You might also be shocked to learn that they react to upgrades pretty similarly. However, the 2JZ will respond better due to its larger displacement if a 1JZ and a 2JZ are similarly modified and producing equivalent power.
Due to the fact that a single large turbo takes longer to spool than two smaller turbos, this will be even more noticeable with single-turbo conversions. Engine displacement, turbocharger size, and maneuverability are all directly correlated. As a result, the 2JZ will be more responsive at equivalent power levels and modifications because it has more displacement power.
Although it is often held that the 2JZ can produce more horsepower, this is primarily because of its displacement.
In practice, the 1JZ’s stock bottom end can safely handle 650700 horsepower, while the 2JZ can handle 800. If we convert this into basic math, we can see that the bottom end of the 1JZ is capable of producing about 260 horsepower per liter, while the bottom end of the 2JZ is capable of producing about 266 horsepower per liter. It goes without saying that there are builds out there that produce far more horsepower than these figures. However, even today, their cast-iron bottom ends are among the strongest ever created.
In terms of applications, the 1JZ’s more rev-happy nature makes it ideal for drift builds because maintaining a slide and making sharp transitions both depend on staying in the upper portion of the rev-range. Because of its shorter stroke, the 1JZ loves to run at high rpm but has little low-end torque. The turbocharger needs more time to spool when the stroke is shorter.
The 2JZ, on the other hand, boasts both low-end torque and a wide torque band, almost like that of a large normally-aspirated engine thanks to its larger stroke and sequential twin-turbo arrangement. Just this alone greatly increases its street use compliance. Strangely, the 2JZ is less dependable when maintained at high RPMs for an extended period of time because to the larger stroke.
There are lots of parts and businesses that focus on these engines. The 1JZ is a little less expensive. When it comes to the construction of both of these engines, there is a clear trend. While most 2JZ builds are insane 10- or even 9-second drag cars, most 1JZ builds are drift cars. Both engines have advantages and disadvantages, but when used properly, they may deliver impressive numbers while preserving the most of their fantastic reliability.
