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.

What 2JZ-equipped Lexus IS300 is this?
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 motor powers a Lexus IS300?
A 2.0-liter twin-scroll turbocharged four-cylinder engine with 241 horsepower and 258 pound-feet of torque powers the 2021 Lexus IS 300. A 3.5-liter V6 engine powers the IS 300 AWD, generating 260 horsepower and 236 pound-feet of torque. Finally, a 3.5-liter V6 engine with 311 horsepower and 280 pound-feet of torque is included in all IS 350 versions. While all-wheel drive variants use a 6-speed automatic with paddle shifters, rear-wheel drive vehicles couple with an 8-speed automatic transmission with paddle shifters.
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.
What distinguishes a 2JZ-GE engine 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.
Is the 2JZ-ge an effective motor?
There are many minor distinctions as well as many significant ones between the two. For increased effectiveness as a normally aspirated motor, the N/A 2JZ is optimized. The 2JZ-GE cannot be turbocharged to produce a 2JZ-GTE.
The N/A 2JZ is a pretty good engine despite being nothing unique. A Camry V6 (1MZ-FE) with a manual transmission will outperform an IS300 with an M/T, stock for stock. The 1MZ has a good powerband (double torque peak at 3500 and 4400 rpm), but it was hurt by internal competition with the 2JZ.
The 2JZ-GTE is an entirely separate species. Despite having the same engine series and general design, installing the 2JZ-GTE into an IS300 requires a lot more labor (read the forums at http://my.is). Strength of the rod, piston, and crankshaft is overdone.
What Lexus had 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.

What vehicles were the 2JZ GTE available in?
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.
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.

What makes 2JZ so strong?
Why is the Toyota 2JZ inline-6 engine a renowned engine in the automobile industry? A brand-new video delves deep into the engine’s internals and explains why it’s so perfect for producing significant power with stock internals.
The engine in the video is essentially the same engine that was in the last Toyota Supra, which is from Papadakis Racing. Its variable camshaft timing on the intake comes from a Toyota Aristo, also known as the Lexus GS in the United States. The remainder of the movie essentially demonstrates how the engine was disassembled, but while doing so, we can see what makes the engine unique. We may thank Japan’s bubble economy for the over-engineered, extraordinarily long-lasting engines that the auto industry produces.
The 2JZ engine is quite durable to begin with because it has a cast-iron block and a closed block. The engine is equipped with bucket-type lifters, which are highly dependable but don’t fit larger camshafts effectively. The number of moving parts is significantly less than, say, a rocker arm system. The head gasket itself appears to be in decent condition for an engine that has been in use for more than 20 years when the head is removed.
Toyota equipped the 2JZ with extremely durable head gaskets and a closed block design, which contributes to the problem. The absence of water openings all around the cylinders makes them incredibly durable. Because of this, tuners can extract a lot of power and boost from the standard internals. Three layers of steel make up the multi-layer head gasket itself. The construction helps create a very tight seal around the cylinder and prevents the gasket from blowing.
For the mechanical types, the rest of the film is pure zen, so relax and take in the teardown above.
