Is it worth fixing a turbo on a car?

The short answer is that it can be worth fixing a turbocharger on a car, but it depends on several factors. Turbochargers are complex and expensive components, so the decision to repair or replace one requires careful consideration. In this article, we'll explore the key factors to weigh when deciding whether to fix a turbo on your vehicle.

What is a Turbocharger?

A turbocharger is a device that increases the power output of an engine by forcing more air into the combustion chamber. It uses the exhaust gases from the engine to spin a turbine, which in turn drives a compressor that pressurizes the intake air. This allows the engine to produce more power from the same displacement, making turbochargers a popular choice for both performance and fuel efficiency.

Common Turbocharger Issues

Turbochargers can experience a variety of problems, including:

• Bearing failure: The bearings that support the turbine and compressor shafts can wear out over time, leading to increased friction and reduced efficiency.


• Oil leaks: Turbochargers rely on engine oil for lubrication, and leaks can cause damage to the internal components.


• Compressor wheel damage: The compressor wheel can become damaged by foreign objects, leading to reduced airflow and performance.


• Turbine wheel damage: The turbine wheel can also be damaged by foreign objects or excessive heat, causing the turbocharger to fail.

These issues can lead to a loss of power, reduced fuel efficiency, and even complete turbocharger failure if left unaddressed.

Factors to Consider When Fixing a Turbocharger

When deciding whether to fix a turbocharger, you'll need to consider the following factors:

• Cost of repair: Turbocharger repairs can be expensive, often ranging from $1,000 to $3,000 or more, depending on the extent of the damage and the make and model of the vehicle.


• Age and mileage of the vehicle: If your vehicle is older or has high mileage, it may not be worth investing in a costly turbocharger repair, as the rest of the vehicle may be nearing the end of its useful life.


• Importance of turbocharger performance: If your vehicle's turbocharger is essential for its performance or fuel efficiency, it may be worth repairing it to maintain the vehicle's capabilities.


• Availability of replacement parts: Some turbochargers may be difficult or expensive to find replacement parts for, making the repair process more challenging.

Ultimately, the decision to fix a turbocharger will depend on your specific situation and the overall condition of your vehicle. It's important to weigh the costs and benefits carefully before deciding on the best course of action.

How much does it cost to fix a turbo in a car?

On average, the cost to replace a turbocharger can be $2,000 or more. The turbo can cost at least $1,500, while labor will typically run $500 or more. However, the type of car you drive and the engine it has will impact the final price you pay.

Is it cheaper to repair or replace a turbocharger?

Budget: If you're on a tight budget, rebuilding the turbo is often the more cost-effective option. It's especially true if the damage is minor and you can restore the turbo to near-new condition.

Can you still drive a car with a bad turbo?

You can technically still drive a car with a bad turbo, but it is not recommended as it can lead to more severe and expensive engine damage. Driving with a bad turbo will result in a significant loss of power, reduced fuel efficiency, and potential damage to other engine components. It is best to stop driving the vehicle and have it towed to a mechanic to avoid catastrophic engine failure.

Risks of driving with a bad turbo

• Catastrophic engine damage: A failed turbo can send metal fragments from its impeller into the engine, causing internal damage that requires complete engine replacement. 
• Loss of power: The vehicle will feel sluggish and unresponsive, making it difficult to maintain speed or accelerate. 
• Damage to other components: A bad turbo can lead to increased oil leaks, carbon buildup, and damage to the catalytic converter. 
• Increased repair costs: The longer you wait, the more expensive the repairs will become as more components get damaged. 

What to do if you suspect a bad turbo

• Stop driving immediately: As soon as you notice any symptoms like excessive smoke, strange noises, or a loss of power, pull over and turn off the engine. 
• Have the vehicle towed: Do not risk driving it to a shop. Call a tow truck to take it to a qualified mechanic for diagnosis and repair. 
• Do not attempt to drive it: The potential for major engine failure makes it an unnecessary risk. 

Can a failing turbo be repaired?

Yes, a turbo can be repaired, a process often called rebuilding, and it is a common and often more budget-friendly alternative to replacing it with a new unit. Rebuilding involves disassembling the turbo, cleaning it, replacing worn components like bearings and seals, and carefully reassembling and balancing the parts to restore factory parameters.

Common turbo repair process

• Disassembly: The turbocharger is taken apart to access the internal components. 
• Cleaning and inspection: All parts are thoroughly cleaned to remove oil and carbon buildup. Components are then inspected for wear and damage. 
• Component replacement: A new core or cartridge, along with bearings and seals, is often the primary replacement part. Other components may be replaced as needed. 
• Balancing: The rebuilt assembly is balanced to ensure smooth and stable operation. This is a critical step to prevent future failure. 
• Reassembly: The components are put back together, with careful attention to alignment and proper torque.

Benefits of repairing a turbo

• Cost savings: Repairing can be significantly cheaper than buying a new turbocharger. 
• Extends lifespan: A successful rebuild can give the turbocharger a new lease on life, extending its service life and potentially the life of the entire engine. 
• Restores performance: A properly rebuilt turbo restores performance, improving acceleration and fuel economy that may have been lost. 

When to consider a repair

• Minor damage: If the damage is not catastrophic, a repair is often a viable and cost-effective solution. 
• Budget constraints: Repairing can be a more accessible option if you are working with a tighter budget. 

Important considerations

• Professional vs. DIY: While some DIY repairs are possible, professional rebuilding shops can use specialized equipment for testing, cleaning, and balancing to ensure factory specifications are met. 
• Potential for greater damage: It is not safe to drive with a faulty turbo, as it could cause further damage to the engine.
