Toyota Motor Corporation developed and built the 2JZ-GTE, a six-cylinder, inline-layout, dual overhead camshaft, air-intercooled, twin turbocharged, cast-iron block, aluminum cylinder heads engine that was made in Japan from 1991 to 2002. The engine’s development and evolution was mostly a reaction to Nissan’s then-successful RB26DETT engine, which had seen great success in the FIAGroup A and Group N touring car championships.
There were two transmissions for the engine that were suitable for all road car applications:

What was the final 2JZ vehicle?
Toyota’s JZ-series was a collection of straight-six engines designed to sprinkling of performance to the company’s road automobiles in the 1990s and 2000s. Following the 1JZ, which had 24 valves and a 2.5-litre displacement, was the 2JZ, whose stroke had been lengthened to 3.0-litres. The JZ series was built significantly stronger than the 7MGTE, which was the precursor to those engines and is notorious for having a variety of cylinder head troubles, making it ideal for some severe tweaking.
Let’s look at the underrated Toyotas that also happened to have JZ-powered engines as the A80 Supra is the symbol for JZ-powered Toyotas. There are a lot of seductive potential bedmates out there.
Toyota Verossa VR25
The Verossa, which replaced the Toyota Chaser, could be equipped with either the FSE or GTE 1JZ engine, depending on the trim level. The VR25, which employs the GTE in single turbo form and produces 276 bhp and 278 lb-ft of torque, is the highest model in the lineup. It distributes its power through a limited-slip differential and either a four-speed automatic transmission or a five-speed manual transmission.
Toyota Aristo
In fact, the Aristo, which was discontinued and only available as the Lexus GS after 2005, was where the famed 2JZ-GTE engine made its premiere. The GTE, which is based on the 2JZ-GE basic block, employs sequential turbos as opposed to the parallel configuration of the 1JZ-GTE. The engine in the Aristo, affectionately known as the “Gentleman’s Supra,” produces 270 horsepower.
Up until the third generation, the Aristo/GS used JZ powertrains, then transitioned to V6 engines with the 3UZ V8 remaining.
Lexus SC300
The first generation Lexus SC, which has a smaller engine than the V8-powered SC400, has a low roofline and an expansive bonnet that give it a streamlined appearance. The 3.0-liter NA 2JZ-GE engine that powers the 1992-released SC300 has been slightly tuned to produce about 245 horsepower, which is five more than the engine used in the Supra at the time.
The powertrain was further enhanced in 1997 with the addition of VVT-i, which allowed the SC300 to achieve a 0-60 mph time of 6.8 seconds in the manual version. This two-door coupe, designed to compete with the Mercedes SL and Acura Legend in the North American market, would be a wise used purchase for someone looking to enter the JZ lifestyle.
Toyota Mark II Blit
With the zany wagon design and the renowned Toyota straight-six and rear-wheel drive, the ninth version of the Mark II is available. JZ engines are available for the Blit over its entire range, from the 2.5-litre iR-S (1JZ-FSE) to the iR-V. (1JZ-GTE). The latter is the top model and adheres closely to that older man’s advice by using a single CT15B turbo to produce the illusive JDM power output of 276 horsepower.
The Mark II Qualis wagon’s rear-wheel drive replacement, the Blit, was built from 2002 to 2007 before being replaced by the Mark X Zio minivan, which had inline-four and V6 engines.
Toyota Crown
The Crown, one of Toyota’s most well-liked saloons, has been a hit since 1955. However, it wasn’t until the ninth generation that it was able to obtain a renowned JZ engine. These straight six engines were used in the Crown from 1991 to 2003, mated to either four or five-speed transmissions, and using either 1JZ or 2JZ variations depending on the year and trim level.
The Athlete wagon, which used the naturally aspirated 2JZ-GE with the VVT-i shared with the formidable A80 Supra, is regarded as the greatest JZ-powered Crown. On the other hand, the Athlete V sedan, which combines a side-mount or front-mounted air-to-air intercooler with a parallel turbocharged 1JZ-GTE engine, can be justified.
Which JZ-powered vehicle, except Supras, does it for you? Do you like the 1JZ or the 2JZ better? Or perhaps you’re a bigger Nissan RB fan? Post your comments below with your ideas!
A 3JZ will there be?
All of your comments have been heard by Toyota. The clamor for a manual transmission are endless. All the criticisms that it utilizes a BMW engine as opposed to a Toyota-built powerplant These complaints will soon cease to exist. The recently unveiled 2021 Toyota Supra features a new A91 Edition, greater power from its six-cylinder engine, which is sourced from BMW, and even a more reasonably priced four-cylinder variant. We had a nagging feeling, though, that Toyota was keeping something much more intriguing a secret. a racecar that is even more thrilling than the Supra GT4.
Toyota has chosen to debut its newest Supra model online after deciding to postpone the 2021 Supra media drive due to coronavirus worries. The Toyota Supra 3JZ Edition, which is scheduled to debut as a 2022 model, only has two objectives: to silence the critics and destroy the C8 Corvette.
There has always been a vocal minority of people who disagree with Toyota’s choice to adopt BMW’s B58 inline-six engine in the fifth-generation Supra. There were Supra enthusiasts who desired another Toyota-built inline-size like to the storied 2JZ found in the fourth-generation vehicle, despite the B58’s considerable degree of adjustability. Today, Toyota unveiled the Supra 3JZ Edition, making that dream a reality.
The 3JZ will be a V8 with two turbochargers, in contrast to its predecessor, which was a twin-turbo inline-six. It’s possible that this is the engine from the Supra racecar prototype we saw being tested. Despite how fantastic this engine already sounds, we now know just how powerful it will be.
What vehicles are powered by a 2JZ?
We must first identify the vehicles that can fit this engine in order to comprehend the vehicles that have it. The 2jz engine is typically found in the following vehicles:
- Lexus Altezza
- Toyota IS300
- Lexus Aristo
- Toyota GS300
- Lexus Crown
- Lexus Chaser
- Cresta Toyota
- Lexus Mark
- Toyota Advances
- Toyota SC300
The list contains the answer to your question regarding the engine’s initial application. The Toyota Aristo introduced the engine first. However, it didn’t achieve the astounding popularity that people had hoped for and was eventually cancelled.
After 2005, Toyota branded the identical Aristo as the Lexus GS. The GTE, which is based on the GE block of the 2JZ engine, comes next. It has several successive turbos. The parallel 1JZ functionality seen in the GTE turbo is interestingly different from this. The 270bhp configuration is very popular as a sports car today.
What HP does a 2JZ have?
These were some fairly remarkable specifications in 1991. The 3.0 liter inline-6 2JZ has twin turbochargers to produce 320 hp and 320 lb-ft of torque. By the standards of today’s performance engines, those figures would seem typical. However, those power numbers were difficult to match in the 1990s. Many bigger, more expensive engines didn’t deliver performance even close to that.
The rest of the Toyota 2JZ specifications show that this engine was made to withstand some substantial power and boost. Strength is the key to this powerplant. As a last point, the Toyota Supra is where the 2JZ-GTE is most famous.
Toyota 2JZ-GTE Strength
The 2JZ-GTE can withstand large boost because to its 8.5:1 compression ratio. The square cylinder shape provides excellent torque and top-end power balance. The closed deck, iron block used by Toyota in the 2JZ is incredibly sturdy. Despite being cast rather than forged, pistons are nevertheless quite robust and sturdy. Additionally, they included oil spray nozzles for cooling the pistons. The list is concluded with a robust forged crank and rods.
The Toyota 2JZ is unmistakably designed for robustness and longevity. You want to see specifications like this on any high-performance engine, almost exactly.
Several times in the article, we’ll return to this subject. The specifications appear great on paper. To tell us this, however, we don’t need specifications or paper. What makes the 2JZ-GTE such a legend is what it actually manages to do. Throughout the text, we’ll refer back to the 2JZ’s positive attributes. For the time being, we only wanted to emphasize how powerful the engine is from top to bottom.
VVT-i Added In 1997
The Toyota 2JZ engine was not updated for use in North America. However, Toyota started making new JDM 2JZ-GTE engines with VVT-i about September 1997. Modern engines frequently use variable valve timing, which enhances both fuel efficiency and power band.
Additionally, it helps the 2JZ’s power band, which some people find attractive about the JDM VVT-i engine. However, finding them can be more difficult, and finding parts can also be more difficult. The advantages and disadvantages of the VVT-i engine might be covered in a separate topic. In the end, apart from the cams and VVT-i, they are almost identical engines. It’s nevertheless a crucial factor to take into account if you’re planning to buy a 2JZ engine.
What Lexus model is a 2JZ?
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 is superior, the 2JZ or the RB26?
Let’s get started with this tasty matchup: Supra vs. GTR! One glance at each specification sheet explains why the RB26DETT and 2JZ-GTE are both halo engines for JDM car enthusiasts: close to 300 PS and healthy torque figures in standard tune, cast iron bottom ends and low weight, 24 valve cylinder heads.
Each engine has a lot of tuning capability thanks to well-engineered mechanical design. Both are substantial inline six cylinder engines that are around the same size and weight.
The 2JZ-enlarged GTE’s displacement produces the same amount of output, but it reaches its peak power 1,200 rpm earlier than the RB26. Additionally, the 2JZ produces 31 lb ft greater torque at 400 rpm less than the RB.
What makes 2JZ so potent?
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.
Is the 2JZ a BMW engine?
In response to widespread demand, BMW has declared that the legendary Toyota 2JZ inline six-cylinder will replace every engine in its lineup. Following substantial public outrage over BMW’s role in the creation of the fifth-generation Toyota Supra, the announcement was made.
What kind of HP is a 1JZ capable of?
YouTube is flooded with videos of tuned JZ engines, but instead of comparing one dyno run to another without context or funding, let’s take a look at two videos showcasing some of the craziest JZ tuning. Both engines have similar tuning potential.
JZ-GTE Dyno tuning
This morning at Fair Lakes Cars & Coffee, a ridiculously loud 1600HP (on spray) Titan Motorsports Toyota Supra showed up. The bottle provides the car with 1400 HP. I don’t know what will do it, but this will definitely make you love Supras.
Scores & conclusion
- xxxxx 1JZ-GTE
- xxxxx 2JZ-GTE
I’ll end by quoting from the wonderful essay by Dustrunnerauto:
Both are among the hottest factory engines ever to be installed in a production car.
“The 2JZ can withstand higher power levels, which is why most people believe it to be stronger. However, they overlook the additional displacement. According to a rough rule of thumb, the stock 1JZ bottom end can produce 650700 horsepower, while the stock 2JZ bottom end can produce 800 horsepower. The 2JZ should be more powerful, wouldn’t you think? Wrong.
“650700 horsepower, or 260280 hp/liter (650 hp/2.5 liters = 260 hp/liter), is the range for the stock 1JZ bottom end. The factory 2JZ bottom end is capable of producing 800, or 266 horsepower per liter.
“The bottom ends of both of these engines have been far exceeded by the figures I just mentioned. However, the bottom end of the 1JZ and 2JZ can consistently produce 266 horsepower per liter. When I use the term “reliably,” I mean that the engine can withstand repeated use under extreme conditions without breaking down.
“Both are among the hottest factory engines ever to be installed in a production car. There are very few engines in existence that have 1,000 horsepower or more.
