The car engine is what provides power to the vehicle and makes it move. There are many different types of engines, but one that is particularly popular among car enthusiasts is the “2JZ” engine.
You may be wondering which cars have this engine, and so in this article, we’ll be taking a comprehensive look at that very question.
The Toyota Supra is one of the most popular cars to ever come equipped with a “2JZ” engine, and the Supra name has become synonymous with this powerful engine. Lexus also used this engine in some of its models, including the IS300 and GS300. Other Toyota models that came with the “2JZ” engine include the Aristo, Chaser, Crown, Mark II, and Verossa.
The 2JZ engine came as a stock option in many of these cars and was incredibly popular among the widest variety of car enthusiasts due to its modding potential and prestige.
2JZ Engine
The 2JZ engine was developed back in the late 1980s and early 1990s. It was designed as a replacement for the older and less powerful “MA” series of engines that were used in Toyota’s cars at the time. The engine made its debut in 1991 in the Toyota Aristo, which is a Japanese market-only car.
The engine quickly gained popularity among tuners due to its high power output and potential for modifications. It became even more popular when Toyota released the Supra in 1993, which came standard with the “Twin Turbo” version of the engine.
The engine is an “inline-six” design, meaning that there are six cylinders lined up in a straight line. This configuration is often used in performance cars because it allows for a high power output while still being relatively compact.
The engine is also very reliable, which is another reason why it is so popular among car enthusiasts. It is not uncommon for cars with this engine to have over 200,000 miles on them and still be running strong.
2JZ Engine Variants
When talking about a 2JZ engine, the two refers to the second generation of the engine as the first generation was known as the 1JZ engine. The “JZ” refers to a family of engines that Toyota developed and used in a variety of their cars.
The “JZ” family of engines includes the following:
- JZA80 – The engine that was used in the Supra from 1993 to 2002
- JZZ30 – The engine that was used in the Toyota Soarer from 1991 to 2000
- UZJ100 – The engine that was used in the Lexus LS400 from 1998 to 2005
- ARZU340 – The engine that was used in the Nissan Skyline GT-R from 1989 to 2002
The First Generation – The 1JZ Engine
The first generation of this engine was known as the “JZ” engine. It made its debut in 1991 in the Toyota Aristo, which is also known as the Lexus GS300. This engine was available in two different versions.
The first was a naturally aspirated version that produced 210 horsepower and 216 lb-ft of torque. The second version was a turbocharged version that produced 276 horsepower and 260 lb-ft of torque.
Secret Behind 2JZ Engine Power
As we already mentioned, the 2Jz engine is very powerful. But what exactly is the secret behind its power?
1. Forged Crankshaft
One of the main reasons why this engine is so powerful is because it has a “forged crankshaft.”
This means that the crankshaft (which is responsible for converting pistons’ up-and-down motion into rotational energy) is made out of very strong and durable material. This allows the engine to handle more power without breaking.
2. High-Quality Pistons
Another reason why the “JZ” engine is so powerful is that it has high-quality pistons. These pistons are made out of a lightweight but strong material, which helps to improve the engine’s efficiency.
3. Better Breathing
The “JZ” engine also has better “breathing.” This means that it can pull in more air, which allows for more complete combustion. This, in turn, results in more power.
All of these factors combine to make the “JZ” engine one of the most powerful and reliable engines on the market.
Frequently Asked Questions
How Much Does a 2JZ Cost?
The cost of a “JZ” engine will vary depending on where you purchase it and what condition it is in. However, you can expect to pay anywhere from $1000 to $4000 for a used engine.
What Is the Best 2JZ Engine?
The 3-liter turbocharged engine that was used in the Supra from 1993 to 2002 is considered to be the best “2JZ” engine. This engine produces 320 horsepower and 315 lb-ft of torque.
Why Did They Stop Making 2JZ Engines?
Toyota stopped making the “JZ” engine in 2005. However, they continue to produce a similar engine known as the “GR” engine. The main reason why they stopped making the “JZ” engine is that emission regulations were getting stricter and it was becoming more difficult to meet them.
What Cars Have a GR Engine?
The following cars have a “GR” engine:
- Toyota 86 (2017-present)
- Toyota Supra (2019-present)
- BMW Z3990i (2019-present)
- Lexus RC350 (2019-present)
As you can see, the “GR” engine is still being used in a variety of cars. This shows that it is a very reliable and powerful engine.
How Much HP Can a 2JZ Engine Make?
The least powerful “JZ” engine produces 210 horsepower, while the most powerful one produces 320 horsepower. This means that the average “JZ” engine can produce around 265 horsepower.
You can however add some tuners which can improve the engine’s power. With the help of a tuner, you can expect to get up to 1000 horsepower from a “JZ” engine.
Can I Swap a Jz Engine Into My Car?
Yes, you can swap a “JZ” engine into your car. However, it is important to note that this is not a simple task. You will need to have a lot of mechanical knowledge and experience to do this correctly.
It is also important to note that not all cars can accept a “JZ” engine. This is because the engine bay needs to be large enough to accommodate the engine.
Can I Turbocharge My Jz Engine?
Yes, you can turbocharge your “JZ” engine. Although, it is important to note that this will void your warranty.
Turbocharging your “JZ” engine can significantly increase its power output. With the help of a turbocharger, you can expect to get up to 1000 horsepower from your engine.
What Is the Difference Between a JZ And a UJZ Engine?
The main difference between a “JZ” and a “UJZ” engine is that the “JZ” engine is made out of iron, while the “UJZ” engine is made out of aluminum.
The “JZ” engine is also slightly taller than the “UJZ” engine. This is because it has a longer stroke.The “JZ” engine is more powerful and durable, while the “UJZ” engine is lighter and more fuel-efficient.
How Reliable Is the 2Jz?
The 2JZ engine is considered to be one of the most reliable engines on the market. It is known for its durability and power. This is why it is often used in performance cars.
However, there are some downsides to the engine. For example, it is known for being fuel-inefficient. This can be a problem if you are trying to save money on gas. Additionally, the engine can be noisy. This can be an issue if you are trying to keep your car as quiet as possible.
