What is the name of the 5.7 engine in the Tundra?
The 5.7-liter engine used in the Toyota Tundra is named the i-FORCE 5.7L V8.
The 5.7L i-FORCE V8 is a large-displacement, naturally aspirated V8 that powered early and mid-generation Tundra pickups (and related Toyota trucks) before Toyota shifted more emphasis toward turbocharged V6s and hybrids in newer models. It typically delivered robust mid-range torque and a strong towing capability, with output around 381 horsepower and 401 lb-ft of torque in most Tundra configurations, and was usually paired with a 6-speed automatic transmission.
Branding and role in the Tundra
Here is a snapshot of the engine's branding and core characteristics as it appeared in the Tundra’s lifecycle.
Key specs include the following:
- Displacement: 5.7 liters
- Configuration: V8, naturally aspirated
- Power: approximately 381 horsepower
- Torque: approximately 401 lb-ft
- Transmission: 6-speed automatic
- Primary applications: Toyota Tundra (and Sequoia in certain years)
In summary, Toyota's i-FORCE 5.7L V8 was the big V8 option for the Tundra's earlier generations, prized for its durability and towing capability.
Legacy and naming
The "i-FORCE" branding ties the engine to Toyota's family of gas-powered powertrains, with the 5.7L version standing as the flagship V8 in that lineup for trucks like the Tundra and Sequoia. In the current era, Toyota has expanded its powertrain options with the i-FORCE MAX hybrid, a different approach built around a 3.5L V6 rather than the 5.7L V8. The 5.7L V8 remains a reference point in Toyota's truck heritage and is frequently cited by enthusiasts and reviewers when discussing the Tundra's legacy of torque and durability.
Summary
The 5.7-liter engine in the Toyota Tundra is known as the i-FORCE 5.7L V8. It served as the truck’s large-displacement gasoline option in older generations, delivering strong torque and towing capability, until newer powertrains shifted the lineup towards smaller, turbocharged V6s and hybrids.
Is the 5.7 iforce a good engine?
Yes, the 5.7L i-Force V8 (3UR-FE) is generally considered a good and reliable engine, known for its power, performance, and durability. While it has some potential issues like cam tower leaks, intake valve springs, and some coolant leaks, these are manageable with proper maintenance and are outweighed by its impressive track record of high mileage and strength.
Strengths
- High performance: The engine provides strong acceleration, with 0-60 mph times around 4.5-5 seconds in early models, and significant torque for towing and hauling up to 10,000 pounds.
- Exceptional reliability: Many owners have reported the engine running strong with 200,000+ miles and even achieving 1 million miles with minimal maintenance, making it a key reason for the popularity of the second-generation Tundra.
- Durable construction: Toyota's extensive durability testing and quality control, including using X-rays to check engine block specifications, contribute to its longevity.
- Simple maintenance: For those with regular oil changes and basic upkeep, the engine is expected to last a very long time.
Weaknesses
- Cam tower leaks: A common issue is oil leaking from the cam towers due to the adhesive used in early models wearing away over time, potentially dripping onto the exhaust manifolds.
- Valve springs: Some early models may have had issues with intake valve springs breaking, which can lead to catastrophic engine failure.
- Coolant leaks: Certain coolant leaks related to the water pump or valley pan have been reported, but these are often considered relatively minor and inexpensive to fix.
Overall
The 5.7L i-Force is a powerful and durable engine that holds a reputation for being very reliable. While it's not immune to problems, these are often minor or early-production issues that can be managed with proper care and maintenance.
Is the 5.7 Toyota engine a Hemi?
No, the Toyota 5.7L engine is not a Hemi, although they are both 5.7-liter V8 engines with similar power output. The Hemi is a trademarked name for a Stellantis (Chrysler/Dodge/Ram) engine with hemispherical combustion chambers, while Toyota's 5.7L V8 is a different design, often called the 3UR-FE or i-Force V8, that uses a different combustion chamber design and has a dual overhead cam (DOHC) setup.
- Engine design: The "Hemi" name refers to the hemispherical shape of the combustion chambers in the Stellantis engine. The Toyota 5.7L V8 has a different design with a different number of valves per cylinder (four) and uses a DOHC valvetrain, while the Hemi uses a pushrod overhead valve (OHV) system with two valves per cylinder.
- Trademark: "Hemi" is a registered trademark of Stellantis. While other engines may use a hemispherical combustion chamber, only Stellantis can legally call their engine a Hemi.
- Displacement and power: While they share a similar displacement of 5.7 liters, they are two completely different engines designed by two different companies.
- Common features: The only significant similarity is that both are V8 engines with approximately a 5.7-liter displacement.
What Toyotas have the 2uz fe engine?
The engines have been used across the 100-series Land Cruiser and its Lexus GX and LX variants, the fourth generation 4Runner, and the Tundra. Toyota's TRD division also offered a bolt-on roots-type supercharger kit for the engine, increasing its power by an additional 118hp to an even 400hp, making it a potent option.
What is the 5.7 Tundra engine called?
It's paired only with a six-speed automatic through at least the 2018. Model year proven to be very refined and a reliable engine it produces 381 horsepower and 401 pound- feet of torque.
