Our attention is on the top bolt-on IS300 modifications. The addition of forced induction is one thing we didn’t mention in our list. The 2JZ-GE can manage power and boost pretty well because it is constructed on the same platform as its more powerful brother. We will reserve our discussion of turbo kits for a separate, more in-depth tutorial because they are a bit more complicated.
Additionally, there were two distinct transmission choices available for the first-generation IS300: a 5-speed manual and a 5-speed automatic known as the e-shift transmission. Both manual and eshift variants will dyno at around 180 whp stock, respectively.

IS300 2JZ-GE Turbo Considerations
The six finest IS300 upgrades we’ve listed here will increase your power by roughly 210210whp for eshifts and 220-230whp for manual transmissions. Even if you surpass such amounts, maintaining natural aspiration is quite expensive. A stroker kit, meth injection, an aggressive tune, and possibly even some nitrous are needed. Let’s just disregard this option for the time being because the stroker kits cost roughly $7.5k.
Therefore, adding a turbocharger is your best bet if you want more power than 230whp. We advise disregarding the majority of the modifications on this list if you do intend to eventually add a turbocharger. It is a waste of money to add headers and y-pipes because they will eventually be obsolete because adding a turbo will alter your entire exhaust system and need that your car be retuned.
Spend your money on handling-related upgrades that will be more important with a high horsepower automobile, such as suspension, braking, tires, and other modifications, if you do intend to add a turbocharger.
Also bear in mind that installing a turbo kit will cost you, at the low end, up to $5k and, if you include the boost controllers, timers, widebands, fuel management systems, upgraded injectors, full exhaust systems, etc., up to $10k+ for a proper setup.
IS300 Cold Air Intake
One of the simplest initial modifications you can make to almost any car is an improved intake. Even though an otherwise stock IS300 won’t gain much performance from adding an intake, it will after the other modifications mentioned are made. Greater combustion is required to generate more power, and air or oxygen is a crucial element in combustion.
An intake will likely add 1-2 whp to a stock 2JZ-GE. However, it will produce gains of 710 whp when coupled with these further IS300 bolt-on modifications. Therefore, even if it might not be the “best first mod,” it is a necessary and one of the least expensive for beginners.
The IS300 3.0L has a variety of different intake choices. They all essentially have the same features and advantages.
A 300 is it 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).
How similar is the IS300 2JZ to the Supra?
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.
Lexus IS300: Does it require premium fuel?
In order to get the best performance out of your IS300, Lexus does advise using premium unleaded fuel with a minimum octane level of 91 or above. To get the most performance and power out of the engine of your car, this is typically advised. Always fill up your car with higher octane fuel; it’s a smart suggestion.
Which motor powers the Lexus IS300?
A 2.0-liter twin-scroll turbocharged four-cylinder engine with 241 horsepower and 258 pound-feet of torque powers the 2021 Lexus IS 300. A 3.5-liter V6 engine powers the IS 300 AWD, generating 260 horsepower and 236 pound-feet of torque. Finally, a 3.5-liter V6 engine with 311 horsepower and 280 pound-feet of torque is included in all IS 350 versions. While all-wheel drive variants use a 6-speed automatic with paddle shifters, rear-wheel drive vehicles couple with an 8-speed automatic transmission with paddle shifters.
The Lexus IS300 was released when?
With the same 3.0 liter six-cylinder engine (the 2.0 liter six-cylinder was not available), the IS 300 sedan made its US debut in July 2000 as a 2001 model, and the IS 300 wagon made its US debut in 2001 as a 2002 model. In Europe, the IS 300 joined the IS 200 in the model lineup.
How many horsepower does an IS300 turbo add?
Our opinion: Finding a turbo kit that is available for less than $1,000 brand new is definitely a rarity, but FastWayRacer has outdone themselves with the least expensive option on our list.

Is the IS300 trustworthy?
The Lexus IS300 is regarded by Toyota fans as one of the most dependable vehicles produced by the company. It had a 3.0-liter inline-six engine with 217 horsepower from 1998 to 2005. Additionally, it could feature an automatic or manual transmission. Although it weighed 3,255 pounds, it offered opulent comfort and athletic performance. Its engine was a naturally aspirated 2JZ GE Supra Mark IV engine that was overbuilt and tested and true. Although there aren’t many issues with this car, those that do warrant addressed.
What kind of boost can a 2jzge withstand?
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.
How durable is the Lexus IS300?
The Lexus IS is a luxurious sedan that is incredibly dependable and can travel, on average, between 250,000 and 300,000 miles with regular maintenance and cautious driving.
