Which Lexus has a 2JZ engine?
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 an end at this time. According to Jalopnik, owners could theoretically triple the IS300’s output without any problems with the right tuning.
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 Is the 2019 Lexus GS?
A mid-size luxury vehicle with room for up to five passengers is the 2019 Lexus GS. The 2.0-liter turbocharged four-cylinder engine in the GS 300 produces 241 horsepower, while the 3.5-liter V-6 in the GS 350 produces 311 horsepower. Rear-wheel drive is standard on the GS 300, and rear- or all-wheel drive is an option on the GS 350. A powerful, rear-wheel-drive GS F with a 467-horsepower 5.0-liter V-8 engine is available. The BMW 5 Series, Audi A6, and Mercedes-Benz E-Class are competitors.
What’s New on the 2019 Lexus GS?
There are no substantial changes to the GS 300 or GS 350. In contrast, the GS F now comes in a limited-edition 10th Anniversary Special Edition with matte-gray paint, blue Brembo brake calipers, black 19-inch BBS wheels, and Michelin Pilot Super Sport tires. For the US market, Lexus will only produce 100 vehicles.
What Features in the 2019 Lexus GS Are Most Important?
LED headlights, heated side mirrors, a power sunroof, an 8-inch multimedia screen, and a power-adjustable steering column are all included as standard features. Full-speed adaptive cruise control and lane departure warning with steering assistance are two examples of standard active safety systems.
A head-up display, a Mark Levinson premium stereo, a heated steering wheel, a motorized trunk lid, and a limited-slip differential are available extras. Built-in navigation with a 12.3-inch screen is also available.
Should I Buy the 2019 Lexus GS?
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.
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.
How much HP is there in 2JZ?
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 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.
How quick is a Lexus GS300?
The GS 300 is the only new Lexus you need to consider if you’re searching for a dependable vehicle. However, the 300 might not be for you if you’re looking for something with a little bit of speed to it.
The top speed of the Lexus GS 300 is 143 mph (mph). Although it can reach 60 mph in 7.4 seconds, there are many faster vehicles available.
Despite this, the 300 might still be worthwhile. Driving a 300 is a delight thanks to luxurious options like leather seats and an excellent sound system, which are common on used cars in the $30,000 price range. Furthermore, it’s doubtful that you’ll ever need to travel faster than 143 mph.

What Does SC Stand For?
The letter SC stands for “Sports Coupe” in the Lexus lexicon. It might be difficult to recall because it is one of the only models made by the manufacturer without a S or an X at the end.
What Does GS Stand For?
Grand Sedan is intended to stand for “GS” in order to accommodate the numerous varied sizes of Lexus sedans. The GS is a larger sedan for individuals who value space, even though it is smaller than the LS.
Which Lexus is 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.
What kind of boost can a 2JZ GE take?
Since the 2JZ-GE has a 10:1 compression ratio, we advise against using more boost than 7-8 PSI before you have to make adjustments to ignition timing, for example.
To get the most out of your setup right immediately, especially if you intend to run more than 56 PSI, we always advise choosing an updated FMIC.
Once you start thinking about exceeding 350400 WHP, you should start thinking about upgrading your fueling systems, such as the pump and injectors.
The 2JZ-stock GE’s compression will also probably only allow you to reliably produce 400450 WHP before you need to start thinking about improvements like a thicker head gasket.
Naturally, there will be a lot more to think about if you have big-power aspirations.
Despite the fact that a number of owners have enjoyed 800 WHP from the factory rods and pistons for a while, we’d advise changing them just to be safe.
What makes 2JZ so potent?
The 2JZ-GTE inline-six engine, which was used in the Toyota Supra’s fourth generation Turbo variant, is largely responsible for the iconic status of the car. For 1993, this 3.0-liter six engine’s 320 horsepower and 315 lb-ft of torque were impressive results from its two sequential turbochargers. But the Supra’s legacy was not only cemented by what Toyota did with its powerplant.
The aftermarket quickly realized that this engine could be tweaked to produce much more than 320 horsepower without seeming to compromise reliability. Modified Supras frequently produce well over 1000 horsepower without any issues. A Supra may easily be transformed into a supercar contender with even a conservative tune. Because of this, the Supra gained notoriety as a tuner icon, gaining a spot in the first Fast & Furious film and the affection of a generation of auto aficionados.
But why did it work so well? Stephan Papadakis, an engine builder, discusses in this 2JZ-GTE dismantling video. The primary cause? This engine is really powerful.
To begin with, a cast iron block was used in all 2JZ iterations. That’s not fantastic for weight, but it’s perfect for maximum strength. In addition, Papadakis notes that the 2JZ has a closed-deck engine, meaning the cylinders are fairly powerful on their own. Because of this, the 2JZ-GTE can withstand high turbo boost pressure. Without having to worry about the engine’s fundamental design, you can push a lot of air through those cylinders.
A cleverly constructed three-layer steel head gasket that can endure high boost pressure without blowing is another advantage of the 2JZ-GTE. The crankshaft is made of very sturdy forged steel. Finally, Papadakis draws attention to the engine’s girdle, which aids the block’s stiffness.
Essentially, when designing this engine, Toyota went crazy. It is an engine for a gas-powered sports vehicle, but it has a lot in common with a high-compression turbo-diesel truck engine in terms of design. It almost seems as though Toyota built the 2JZ with boost-obsessed tuners in mind from the beginning.
Make sure to view the entire Papadakis video. If you ever decide to dissect a legend yourself, it’s a fascinating look inside and is packed with useful information.
