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.

What models of Lexus have a 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).
Which motor powers an IS300?
The 3.5L, V6 engine that the Lexus IS 300 offers as an option produces 260 horsepower. Drivers can choose between AWD and RWD, depending on which suits them best.
Is IS 300 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?
What model of Toyota is the 2JZ?
- 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).
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.
What Is the 2019 Lexus IS?
The Lexus IS is a five-passenger compact premium sports automobile. The all-wheel-drive IS 300 utilizes a 3.5-liter V-6 engine with 260 horsepower, while the rear-wheel-drive IS 300 has a 241-horsepower, turbocharged 2.0-liter four-cylinder. A 311-hp, 3.5-liter V-6 powers the IS 350 in both rear- and all-wheel-drive configurations. The Audi A4, Mercedes-Benz C-Class, and BMW 3 Series are competitors.
What’s New on the 2019 Lexus IS?
The turbocharged four-cylinder drivetrain in the rear-wheel-drive IS 300 has reportedly been retuned by Lexus for improved throttle response, transmission efficiency, and turbocharger reaction. Headlights with three beams are an option.
What Features in the 2019 Lexus IS Are Most Important?
LED daytime running lights, a power sunroof, dual-zone automatic air conditioning, and a 60/40-split folding rear are all included as standard equipment. Forward collision warning with automated emergency braking, lane departure warning with steering assistance, and adaptive cruise control are all included as standard active safety features.
The available amenities include a Mark Levinson premium radio, a heated steering wheel, heated and ventilated front seats, a blind spot warning system with rear cross-traffic alert, and a power rear sunshade.
Should I Buy the 2019 Lexus IS?
The IS provides a rather comfortable ride and plenty of room for the backseat passengers, but it lacks the necessary level of driver involvement for a sports sedan. In addition, we don’t like the Remote Touch multimedia system that Lexus uses, and some of the interior trim looks too cheap for a luxury vehicle.
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.
