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 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 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.
The Lexus IS300 is a 2JZ.
The larger Lexus GS300 sedan’s 2JZ-GE 3.0-liter DOHC 24-valve straight-six, which may be traced back to the previous Toyota Supra, is the same engine that powers the IS300.
How far can a 2JZ travel?
There are several reasons why the fourth-generation Toyota Supra is legendary, but one of them is its dependability. The 3.0 liter 2JZ straight-six in this Supra, which has allegedly racked up 520,000 miles, is particularly bulletproof. The motor, according to the owner, has also “never been touched.”
The owner of the vehicle provided Hoover Toyota in Alabama with these photos. Although the Supra isn’t for sale, the dealer nonetheless posted images and details about the vehicle on Facebook.
Despite having 520,590 miles on the clock, the non-turbo Supra is said to be free of rust and to have undergone no significant engine work. Unfortunately, no other information is given, such as the year of manufacturing or other characteristics. This Supra only has 220 horsepower, which is 100 fewer than its turbocharged predecessor.
You can make fun of Toyota for producing a decent number of unremarkable, ordinary cars, but you must recognize that every product it produces is dependable. You can be sure it will last whether it’s a humdrum Camry, a 4Runner, or a Supra like this.
Which Lexus model has a 1UZ?
The first generation Lexus LS 400/Toyota Celsior introduced the 4.0 L; 242.1 cu in (3,968 cc) all-alloy 1UZ-FE in 1989. The engine was gradually released across a number of different models in the Toyota/Lexus lineup. With a bore and stroke size of 87.5 mm and 82.5 mm, the engine is oversquare by design (3.44 in3.25 in). [2] With features like 6-bolt main bearings and belt-driven quad-camshafts, it has proven to be a powerful, dependable, and smooth engine. The timing/cam belt also powers the water pump. Steel is used in the construction of the crankshaft and connecting rods. Hypereutectic pistons are used.
One of the few road-going engines with FAA approval for use in aircraft is the FV2400-2TC variant.
Its standard, original trim produces 191 kW (256 horsepower; 260 PS) of power and 353 Nm of torque (260 lbft).
[2]
With lighter connecting rods and pistons and an improved compression ratio to 10.4:1, the engine had a minor revision in 1995 and now produces a maximum of 195 kW (261 horsepower; 265 PS) at 5,400 rpm and 365 Nm (269 lbft) at 4,400 rpm.
With the introduction of Toyota’s VVT-i variable valve timing system in 1997 and an additional 10.5:1 compression ratio increase[2,] output and torque were increased to 216 kW (290 hp; 294 PS) at 5,900 rpm and 407 Nm (300 lbft) at 4,100 rpm. 224 kW (300 horsepower; 305 PS) at 6,000 rpm and 420 Nm (310 lbft) at 4,000 rpm were the output ratings for the GS400.
The Ward’s 10 Best Engines list for 1998 to 2000 included the 1UZ-FE.

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.

Was a 1JZ included with the IS300?
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 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).
What vehicles feature a 1JZ?
Actually, the Soarer GT (JZZ30), also known as the Lexus SC on other continents, was the first vehicle to use the 1JZ engine.
It’s important to note that each of these engines were available with and without turbocharging. They also received direct fuel injection during the latter years of manufacturing.
We’ll concentrate on the top-of-the-line turbocharged cars, though. The 1JZ GTE actually has a lot of characteristics with its predecessor, the 7M GTE, but without all of the problems. In essence, it was the 7M executed correctly.
The 2.5-liter, four-valve-per-cylinder 1JZ inline-six engine has double overhead cams (DOHC). It has an over-square design because of its 86 mm (3.39 in) bore and 71.5 mm (2.81 in) stroke measurements. An engine will often be more rev-happy as a result than an under-square unit. Variable valve timing from Toyota was added to later models (VVT-i). It has two parallel turbochargers in its 1JZ GTE configuration, which are supplied by either a front- or side-mounted air-to-air intercooler.
As compared to the regularly aspirated version’s 10:1, it also has a decreased compression ratio of 8.5:1.
The 1JZ GTE produced the promised 280 horsepower (206 kW) at 6,200 RPM and 279 pound-feet (378 Nm) at 2,400 RPM with a stock boost of 9 psi (0.62 bar).
The Toyota Chaser (JZX100), a four-door sleeper sedan that uses the 1JZ GTE, is one of the most renowned vehicles. It can sprint from 0 to 62 mph (100 km/h) in about 5.6 seconds in stock form.
Toyota Chaser/Cressida (JZX81, JZX90, JZX100, JZX110), Toyota Soarer (JZZ30), Toyota Supra Mk III (JZA70, but exclusively in Australia and Japan), Toyota Verossa, Toyota Crown (JZS170), and Toyota Mark II are among the vehicles powered by the 1JZ GTE.
