Here’s a closer look at the T24A-FTS, a 4-cylinder Turbo engine that recently replaced their old V6.
When Toyota opted to replace the classic V6 engine in the 2023 Highlander with the T24A-FTS, a new 4-cylinder turbo engine that really made its debut in the 2022 Lexus NX350, it made headlines.
The Car Care Nut YouTube host recently published a new video that takes an in-depth look at the engine change and what it means for Toyota owners as he explains the differences between the new engine and the common (but similar) Toyota A25A motor found in a variety of other Toyota vehicles in an effort to help clarify what this exactly means for Toyota owners.

Which turbobrand does Toyota employ?
Toyota uses a variety of turbochargers at the factory, including the TOYOTA, which is now IHI/CLOVER, and GARRETT Advancing Motion. There are a few tips to keep in mind when identifying a Toyota turbocharger.
Why is the V6 being phased out by Toyota?
The new engine, according to Toyota, is more environmentally friendly than the previous V6 engine. As well as improving CO2 emissions, it promises a 50% reduction in NOx and NMOG. But why not the Hybrid if those qualities are crucial to a buyer? For a complete update on the 2023 Highander, keep an eye on Torque News.
How durable are Toyota turbochargers?
Turbochargers are very trustworthy. In truth, blown turbos are typically caused by issues with engine lubrication or the entrance of foreign objects, and less than 1% of warranty inspections discover a problem with the turbo itself.
OIL/LUBRICATION
Your car’s engine oil is essentially its life force. It functions to cool them while in use, prevent corrosion, and lubricate important moving parts.
The turbocharger requires a steady stream of pure, high-quality oil. Insufficient oil (oil starvation), the wrong kind of oil, or poor-quality oil will cause pollutants to accumulate in the engine (oil contamination). The inside of the turbo may sustain abrasive damage as a result.
It’s crucial to replace the oil filter and engine oil at the manufacturer’s suggested intervals.
DAMAGED SEALS
Oil will seep into the exhaust system if the seals between the compressor and the engine start to wear out or crack. Because of this, the turbo has to use more effort to raise air pressure.
Overspeeding is another name for this problem. In the end, it will decrease the turbo’s effectiveness and boost output.
FOREIGN OBJECTS/DEPOSITS
The compressor at the front and the turbine at the back are the two basic parts of a turbocharger. Foreign materials like dirt, leaves, and small stones can occasionally enter the turbo through either the compressor inlet or turbine inlet.
The air filter is frequently where the foreign object enters the compressor housing. In contrast, if the turbine is harmed by a foreign object, the issue is typically with the engine.
If foreign items begin to harm the compressor wheels or turbine blades, the turbo’s efficiency will suffer. Your air filter should be serviced and replaced on a regular basis to avoid this from happening. Additionally, you must inspect your turbo for debris.
WEAR & TEAR
Although turbos are intended to last the lifespan of the car (or roughly 150,000 miles), depending on how hard you drive the car and how well the turbo was built initially, it’s likely that they will eventually wear out.
Do turbos reduce engine longevity?
No, modern turbochargers are built to survive as long as the car itself. The fact is that boosted engines need just as much upkeep and attention as a naturally aspirated engine does. Does a turbocharger shorten an engine’s lifespan?
What is a turbo engine’s drawback?
Recall how we said a turbocharger will give you extra power? So, higher power translates to more energy produced each second. This implies that you must exert greater effort when using it. Thus, you need to consume more fuel. Theoretically, a turbocharged engine is no more fuel efficient than one without. Possibly not a significant drawback, but something to keep in mind.
Why, therefore, don’t all engines have turbochargers? After all, more power from a similar-sized engine sounds fantastic! As it turns out, turbochargers don’t always provide the best and most efficient fuel economy. Many offer noticeably inferior fuel efficiency than their competitors. So choosing hybrids and other cutting-edge technologies is the best course of action for saving fuel.
Reliability is also another drawback. An regular engine gains an additional level of mechanical complexity when a turbocharger is added to it. Because more things could go wrong, it needs maintenance more frequently. and hence raise the price of the turbocharged engine. When using a turbocharged engine, you want to squeeze out additional performance from the same fundamental architecture. However, acquiring more also means receiving higher temperatures and pressures, which accelerates the failure of parts.
You can bring the turbochargers to our turbo rebuild company on Long Island if they do break down. We can successfully address and resolve the underlying problems. While staying within your budget, of course. Furthermore, no work will be approved without your consent. Get dependable turbo installation! We’ve been doing what we do for years.
Is a V6 superior to a 4 cylinder turbo?
When properly designed, modern turbocharged four-cylinder engines will either outperform or be competitive with naturally aspirated V6 engines in practically every category. Compared to a natively aspirated V6, turbo-fours are lighter, more efficient, and occasionally more powerful. A V6 will only ever be superior at towing, and just that.
Real World Comparison
The specifications for the turbocharged 2.5L four-cylinder are shown below for numerous new 2021 Mazda models, including the CX-5, CX-30 Turbo, and Mazda3 Turbo. The new 2021 Mazda3 Sedan 2.5 Turbo AWD is contrasted with its counterpart, the normally aspirated 2021 Toyota Camry XSE V6 FWD. The data speaks for itself.
*Higher numbers correspond to ratings with Premium fuel; lower numbers correspond to ratings with Regular fuel.
The power output of the 2021 Mazda3 Turbo and the 2021 Toyota Camry is comparable. But the 2021 Mazda3 Turbo has AWD as standard, while the 2021 Camry only has FWD when powered by the V6. Although AWD always reduces fuel efficiency, the Mazda3 Turbo’s mpg is equal to that of the Camry V6.
Do turbo engines pose a risk?
Although, once again, that wasn’t always the case, it appears that when customers reported problems, the issues were more often with the engine than the turbo. Overall, the data indicated that turbocharged engines were dependable and efficient, with occasional problems being caused by a number of factors, including the turbocharger itself and the engine computer.
“In actuality, it can take several model years for automakers to implement such new technology properly.
Since the relative newness of turbocharging systems to each company appears to be correlated, it is expected that as time goes on, these systems will improve and become more dependable and effective for businesses who are more recent entrants to the turbocharged engine industry.
How durable are four-cylinder turbo engines?
Despite the fact that certain turbocharged engines are dependable, turbo engines frequently have additional issues. A normally aspirated (non-turbo) engine has fewer parts than a turbocharged engine. These include an intercooler, boost control system, vacuum pump, exhaust wastegate configuration, and a more intricate crankcase ventilation system (PCV). Failure of the turbocharger itself is not unusual. More things can go wrong the more parts there are.
Higher combustion chamber pressure causes higher crankcase pressure when the cylinder walls and piston rings deteriorate with increased mileage. This may lead to oil leaks that appear in numerous locations and are challenging to rectify.
Having said that, many turbo engines have a lengthy lifespan. Consider the Mark IV Volkswagen Golf / Jetta’s turbodiesel (from the early 2000s). With proper maintenance, many of them are operating well into 200K miles. Learn more about engine maintenance.
Does Toyota produce a V6 turbo?
Two new engines are being produced exclusively by the plant for the 2022 Tundra.
Birmingham, Alabama (October 18, 2021)
Toyota Motor Manufacturing, Alabama (TMMAL), along with local and state officials, hosted a celebration to mark the first engine for the brand-new 2022 Tundra to leave the factory. These new engines, a twin-turbo V6 driven by gas and an electric hybrid system, usher in the next generation of powertrains made in Huntsville.
The $288 million investment in Toyota’s new twin-turbo V6 engine line included the creation of 450 new employment. That increased the number of people employed at the plant to 1,800, which was the highest hiring need in Toyota Alabama’s history. The completion of this project, which was first announced in February 2019, represented Toyota Alabama’s fifth expansion. Toyota Alabama has made a total of $1.2 billion in investments and can currently produce 900,000 engines annually.
The 1,800 employees at the facility will have stable jobs for the foreseeable future because Toyota Alabama is the only manufacturer of both engine versions for the 2022 Tundra in North America.
According to Jason Puckett, president of Toyota Alabama, “Our team members in Alabama recognize the confidence and trust Toyota places in us since we are the only facility selected to make engines for the all-new Tundra.”
Our 20th anniversary and the introduction of the new twin-turbo V6 series serve as a reminder of how fortunate we are to have such amazing team members who have helped Toyota Alabama become renowned as “the engine capital of the world.”
The 2022 Tundra’s twin-turbo V6 engine options are being produced on the largest Toyota engine line in North America, which is 142 yards long. With a capacity to create 18,000 engines each month, the V6 Turbo line will be able to produce a new engine every 58 seconds. With the addition of these extra engines, Toyota Alabama will now be able to produce up to 900,000 engines annually.
Later this year, the brand-new 2022 Tundra goes on market. Up to 389 horsepower and 479 lb.-ft. of torque are produced by the standard i-FORCE 3.5L twin-turbo engine. The most potent engine in the Toyota lineup is the i-FORCE MAX, which has 437 horsepower and 583 lb.-ft. of torque.
According to Governor Kay Ivey, “our state and Toyota Motor Manufacturing Alabama have shared a mutually beneficial relationship for the previous 20 years that has produced extraordinary results for Alabamians.
Toyota’s $288 million investment to create the brand-new twin-turbo V6 engine serves as more proof that Alabama is the best state in which to conduct business.
Will Toyota produce a Tacoma turbo?
A 3.5-liter gas V6 engine used in the present Tacoma is extremely comparable to that seen in the 2022 Highlander. Toyota is probably going to stop making the V6 in a number of its vehicle lines. It implies that the new 2.4-liter turbo I4 will also be available in the following Tacoma. Since the Tacoma and Highlander do not share a common platform, a new engine will need to be developed to fit between the frame rails of the Tacoma.
If the upcoming Tacoma is turbocharged, I hope it increases the truck’s fuel economy (at least by 1 MPG) in comparison to the V6. I’m hoping it at least keeps the same load-carrying capacity while accelerating more quickly.
Toyota started producing turbocharged engines when?
Toyota provided a turbocharged engine option on both its pickup truck and the first generation 4Runner in the middle of the 1980s, when turbocharging was mainly used in sports cars and other specialty vehicles.
