With high dependability and exceptional performance capabilities, it is impossible to identify many shortcomings in these engines. No engine, however, is perfect or completely bulletproof. As a result, throughout this article, we will identify and discuss the many benefits and drawbacks associated with the Toyota 5.7 V8.
Just so you know, the Toyota 5.7L V8 engine is also known as the 3UR-FR engine. The Toyota 5.7L 3UR-FE engine has aluminum heads and blocks, which helps to reduce curb weight for Toyota’s highest displacement engine in the UR family. The 5.7L V8 engine was created for Toyota’s heavy vehicle and truck applications. Unfortunately, rising demand for more fuel-efficient engine systems may spell the end of the Toyota 5.7 V8 engine. One of this system’s obvious flaws is its lack of fuel economy. Regardless, the 3UR-FE’s structural integrity and performance value are undeniable.
With that stated, let’s take a look at the Toyota 3UR-FE’s fundamental engine specs, as well as a list of its applications, in the sections below.
Toyota 5.7 V8 Engine Specifications
The following are the basic engine specs for the Toyota 5.7L V8 engine:
The Toyota 5.7L V8 engine, as previously stated, has the highest displacement of any engine in the Toyota UR series and was designed to be used in larger Toyota automobiles and trucks. The 3UR-FE’s progressive design was created to replace the 4.7L 2UZ-FE. The 3UR-FE, like its predecessors, employs an aluminum cylinder block with a 90-degree V angle construction. In addition, each Toyota UR engine has a 94mm bore.
Aluminum alloy headers, four valves per cylinder, and two overhead camshafts are used in this design. Furthermore, no direct injection occurs throughout the 3UR-FE. The engine instead has a sequential fuel injection method. Toyota’s 5.7L V8 engine features three notable Toyota technology systems: Dual Variable Valve Timing-intelligence (Dual VVT-i), Acoustic Control Induction System (ACIS), and Toyota’s DIS (Direct Ignition System). These engines are well-known for their dependability and durability, which we will investigate and discuss further in this article.
Now that we have a better knowledge of the Toyota 3UR-FE’s engine specifications and overall design, let’s look at a complete list of its model applications.
What Vehicles Make Use of the Toyota 3UR-FE Engine?
Surprisingly, the same models that used the Toyota 5.7 V8 when it was first introduced in 2007 will continue to do so in 2021. As a result, the 3UR-FE’s design integrity and adaptability are reaffirmed. Having stated that, the models that utilise the Toyota 5.7 V8 engine are as follows:
- Sequoia
- Tundra
- Toyota Land Cruiser
- LX570 Lexus
This engine, once again, was meant to be used in Toyota’s bigger automobiles and trucks. The 381 horsepower and 401 lb-ft of torque are regarded as enough or decent for many applications. As a result, many Toyota aficionados see these engines as not only reliable but also versatile. Now, let’s take a closer look at the general reliability of the 3UR-FE engine, including some of the most regularly encountered issues.
What is the dependability of the Toyota 5.7 V8?
The 3UR-FE is the most dependable engine in the Toyota UR engine family. Extensive reliability testing confirmed how durable this engine truly is. Many drivers expect their Toyota 5.7 V8s to last up to 300,000 miles before requiring major or costly repairs. However, achieving these higher mileages is entirely dependent on proper maintenance and upkeep (i.e., using high-quality fuel and oil, as well as timely oil and oil filter changes). However, no engine, including our 3UR-FE, is completely bulletproof or perfect throughout.
High oil consumption owing to malfunctioning piston oil rings is a prevalent issue for many drivers. True, oil consumption rises with wear and time. However, this issue is recurring more frequently than expected for many Toyota 5.7 V8 owners. As a result, it’s critical to keep an eye on your oil levels in order to prevent further engine damage and extend the life of your engine.
Furthermore, the 3UR-FE has recurring issues with its crankcase ventilation system sensor. Aside from that issue, a number of electrical components lack the structural integrity required to be considered extremely reliable. Furthermore, leaking water pumps are a common and bothersome problem for many Toyota 5.7L V8 owners. However, we want to emphasize that the 3UR-FE is one of the most reliable engines in this Toyota engine series.

Toyota 3UR-FE Upgrades and Modifications
Many Toyota 5.7L V8 applications are both tough and useful. As a result, many drivers may be looking for the right tweaks or upgrades to improve the capabilities of their 3UR-FEs. This section will concentrate on the most popular upgrades for increasing the power and performance of your Toyota engine system. Our aggregate list of upgrades below will get more time-consuming and expensive over time. However, it’s important to emphasize that bigger gains require a combination of helpful mods, a good tune, and proper installation methods. Finally, let’s look at several tweaks that can assist drivers get the most bang for their dollars.
Cold Air Intake 3URFE
To begin, a cold air intake, like many of the engines we’ve looked at, is a simple and inexpensive adjustment that helps enhance power. Promoting good airflow is closely related to increasing engine power. It’s worth noting that many stock models that use the 3UR-FE have restrictive air intakes that will benefit from an update. However, as previously stated, more significant power gains will necessitate additional supportive mods, a good tune, and an upgraded intake. It’s advisable to go with recognized manufacturers like K&N, Spectre, Injen, and others. When it comes to aftermarket parts, our golden rule is “you get what you pay for.” Sure, there are numerous low-cost cold air intake choices on the market today. However, spending a little more on aftermarket parts can often result in better structural quality and engine longevity.
Toyota 3UR Headers Upgrade
This brings us to our next more expensive and serious repair, improved headers. Once again, we are attempting to promote more efficient airflow. Upgraded tubular heads frequently provide more total airflow than stock manifolds. This is particularly true for Toyota’s 5.7L V8 engine arrangement. The faster exhaust emissions can depart the car, the more power the engine can generate. As a result, improved headers can be a critical component in achieving greater horsepower and torque benefits.
E.C.U. for Performance
The engine control unit, or E.C.U, is in charge of operating the engine’s electronic components. Upgrading the E.C.U. to a high-performance aftermarket option can result in increased total power. This change will result in more aggressive fuel and spark delivery, allowing the engine to produce more power. It is vital to emphasize the necessity of purchasing a high-quality aftermarket product once more. When considering a performance E.C.U, stick to reputable companies and avoid sacrificing quality for a lower price.
It’s worth noting that supercharger kits are one of the more extensive, though frequently used, upgrades. Due to the high cost and potentially difficult installation procedures, many drivers consider this update to be their final resort. Turbochargers propel additional air into the engine through the intake. Again, increased airflow allows the engine to generate greater power. Toyota provided TRD supercharger kits for several of their available models, basically making it the best, if not the only, option for many 3UR-FE cars. Before we wrap up our Toyota 5.7L V8 guide, we must emphasize the importance of supportive mods and a good tune. Drivers will not experience significant benefits without a combination of well-researched and well implemented modifications, and they may also lead to a rapid degeneration of their engine’s lifespan.
