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.

Is there a 2JZ engine in the 1998 Lexus SC300?
However, many people are unaware that the Lexus SC300 is practically the mechanical cousin of the Toyota Supra. This is due to the 2JZ engine being shared between the SC300 and Supra. Yes, the Lexus SC300 has a similar engine to the Toyota Supra.
Additionally, the SC300 and the Supra also use the same suspension parts. Despite this, the SC300’s suspension setup and ride quality are far less harsh than those of the Supra because the SC300 wasn’t designed with a racing-level ride in mind to begin with. The suspension is more in line with what you would expect from a Lexus than a Suprait is softer, considerably more forgiving, and more comfortable.
If you’ve ever heard the smooth-but-aggressive, traditional exhaust note of a 2JZ, you’ll be able to appreciate why the Lexus SC300 is an underestimated vehicle. For reference, a 2JZ engine was one of the ones used in the sound mix of Brian’s Nissan Skyline GT-R in the motion picture 2 Fast 2 Furious, starring Paul Walker (Along with an RB26DET and RB30DET, both single-turbo).
A SC300 is it a Supra?
The initial version of the Lexus SC, sold in Japan as the Z30-gen Toyota Soarer, wasn’t particularly athletic. According to Hagerty, it made its debut in the SC400 variant with the 250-hp 4.0-liter V8 and 4-speed automatic from the modern LS400. To be fair, Car and Driver claims that the Mk4 Toyota Supra could also be bought with that automatic.
However, Lexus released the SC300 in 1992. According to Dust Runners Auto, it included leather seats, wood trim, and motorized adjustments for “everything,” just like the SC400. Additionally, traction control was an add-on option. But the Lexus SC300 has a 3.0-liter six-cylinder engine with 225 horsepower and 210 lb-ft of torque in place of a V8. It is essentially a Mk4 Toyota Supra engine because it is the same as the one found in the first-generation IS300.
What model of Lexus is the 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.
The 2JZ is a v6.
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 introduced 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.
Is the 2JZ-GE trustworthy?
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.
The best 2JZ engine is which one?
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.

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.

What vehicles featured the 2JZ GTE?
- Toyota 6-speed manual V160 and V161 (jointly developed with Getrag as the Type 233)
In 1991, the 2JZ-GTE initially propelled the Toyota Aristo V (JZS147), then in the Toyota Supra RZ it became Toyota’s king of performance (JZA80). The previous 2JZ-GE served as its mechanical foundation, but it varied in that engine used sequential twin turbochargers and an air-to-air side-mounted intercooler. The 2JZ-GTE of the Supra features recessed piston tops, which results in a lower compression ratio, oil spray nozzles to help cool the pistons, and a new head (redesigned inlet/exhaust ports, cams, and valves). The 2JZ-GE of the Supra has the same engine block, crankshaft, and connecting rods. The original engine was phased out as a result of Toyota’s addition of VVT-i variable valve timing technology to the engine commencing in September 1997. As a result, the maximum torque and horsepower for engines selling in all markets were increased. Aristo, Altezza, and Mark II, later 2JZ-GE VVT-i equipped cars, share a separate part number for weaker connecting rods.
Its commercially claimed output was increased from 230 PS (169 kW; 227 hp) to the current industry maximum of 280 PS (206 kW; 276 hp) at 5600 rpm by the addition of twin turbochargers, jointly developed by Toyota and Hitachi. When the VVT-i was introduced in the production year 1997, the torque was later reported as 46 kgm (333 lbft; 451 Nm), up from the initial 44.3 kgm (320 lbft; 434 Nm) at 4000 rpm. Japan’s now-defunct Gentlemen’s Agreement solely between Japanese automakers selling to the Japanese domestic market enforced the mutually agreed, industry-wide output ceiling. According to Toyota, the engine’s output in the North American and European markets was boosted to 320 horsepower (239 kW; 324 PS) at 5600 revolutions per minute. [4]
With the help of updated stainless steel turbochargers (ceramic for Japanese models), improved camshafts, and larger injectors (550 cc/min for export, 440 cc/min for Japanese models), the export version of the 2JZ-GTE was able to produce more power. The exhaust-side propeller shaft of the CT20 turbine built to Japanese specifications and the CT12B turbine built to export specifications can be swapped out. Additionally, the more robust turbine housings, stainless steel turbine and impeller fins, and export-only CT12B turbine were added. There are various Japanese CT20 turbine variations that can be distinguished by their B, R, and A part number suffixes (e.g.: CT20A).
A Supra or a Lexus SC?
The Lexus SC Remains an Underrated ’90s Classic: A Supra Without the Hype. One of the most recognizable Japanese sports cars of all time is the fourth-generation Toyota Supra.
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.
