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.
When did the Lexus IS300 get a 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.
What vehicle’s engine is a 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).
What makes the 2JZ engine so effective?
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 helps the block’s rigidity.
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.

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.
Which Lexus model is superior, the ES or the GS?
Both vehicles use a six-cylinder engine and a six-speed automated transmission. The 2018 Lexus GS boasts 311 horsepower, higher torque, and worse gas consumption than the 2018 Lexus ES, which has 268 horsepower. Unlike the ES, which only comes with front-wheel drive, the GS also comes with all-wheel drive.
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.
What distinguishes the Lexus GS300 from the 350?
Since the GS 350 and GS 300 are identical vehicles, they have identical features and choices; the only distinction is in the powerplant. The V6 engine of the GS 350 is stronger, and all-wheel drive is an option. On the other hand, the GS 300 is more economical and only comes with rear-wheel drive.

Discover the most potent car that Lexus has ever produced. The Lexus GS F flawlessly mixes power, style, and grace into one ideal performance vehicle, with an amazing 467 horsepower and top track speed of 168 MPH.
Is the 2JZ-ge an effective motor?
All 2JZ versions are regarded as legendary in the enormous realm of 2JZ engine discussions. Since the DNA of the 2JZ-GE and 2JZ-GTE is almost identical, their similarities outweigh their differences. Having stated that, the argument between 2JZ-GE and 2JZ-GTE rages on. In the end, neither option is likely to disappoint you.
Despite being siblings, the 2JZ-GE and 2JZ-GTE have some significant variances. The sequential twin-turbos on the GTE dramatically boost horsepower and torque, which is the most notable improvement.
Nearly every other distinction between the two 2JZ types may be attributed to the GTE’s forced induction. Toyota enhanced intake flow when designing the cylinder head for the GTE. The 2JZ-GTE uses recessed piston tops, which reduce compression and make boost safer for internal components. When it comes to the GTE’s incorporation of piston oil squirters, the same mindset is at work.
Both the 2JZ-GE and 2JZ-GTE are among the most powerful production engines to date, notwithstanding. As a result, both have a ton of aftermarket potential and tons of information available. Toyota’s inline-6 engine is definitely going out with the 2JZ series. Many people feel that nothing greater will ever exist.
