Vehicle owners who notice a turbo going bad usually need to make a difficult decision: to turbo repair or replace the turbo? As to the reason turbo goes bad, it could be due to excessive wear, i.e. car wasn’t serviced regularly. Or it may be the turbo you bought used had a defect. A failing turbo has to be repaired or replaced promptly for safe driving. When the turbo is not done in good time, other parts of the engine will get damaged, which will raise the bill significantly.

But before taking any major action about turbo, vehicle owners should weigh out all the pros and cons: Repair or replace the turbo? Which option should you go for? We will try to help you decide this critical issue and make the best choice for your car/truck/SUV.

Signs Your Turbo Needs Attention

If considering whether to repair or replace your turbocharger, there are some signs you should be aware of that signal when it has failed – or failed prematurely – and when it should be considered for replacement. Symptoms of a failing turbo are:

Loss of Power

If the turbocharger feels like it is failing to provide more power to the engine, or if the power delivered by your car feels weak, the turbo is likely suffering from a failing compressor wheel or worn bearings.

Excessive Smoke

A common starting indicator for turbo trouble is blue or white smoke of either variety coming out of the exhaust pipe. This happens when oil is leaking into the exhaust system, often due to damaged turbo seals.

Unusual Noises

If the noise has anything of a grinding, whining or rattling nature coming from the turbo area, it can indicate that something inside is wrong, either shaft imbalances or worn-out bearings. How the turbo is designed can affect the kind of noise it makes, but the inability of a turbo to spin smoothly will likely lead to bigger problems.

Boost Pressure Issues

When experiencing a boost loss, which is when the turbo fails to push the right amount of boost (the pressure) it should, a common reason is due to the wastegate, compressor wheel, or intercooler failing. This can result in the vehicle having less power and worse fuel economy.

When to Choose Turbo Repair

Sometimes just the turbo needs to be repaired rather than replaced, particularly when the damage is to a single component. Here you have the scenarios where turbo repair might be your best option:

Minor Damage to Internal Components

When it breaks, it usually just needs an individual bearing, seal or axle to be replaced, rather than replacing the entire turbocharger. This is one of the advantages of these robust pieces of equipment. Turbocharger repair kits exist for an ever-growing list of models that allow certain parts to be replaced, rather than having to get a full unit.

Limited Budget

Most of the time, it is cheaper to repair the turbo than to get a new one. If your budget is limited, you might be better off getting a repair on what’s there now, especially if the damage is limited and does not require that everything will be disassembled and rebuilt.

Low-Mileage Vehicle

If your car has generally low mileage and the turbo hasn’t seen a lot of wear, repairing it could get your turbo back in working order and push it out for a couple of more years without needing a full replacement. When properly taken care of, a turbo can last for a good long while with just a little TLC.

When to Choose Turbo Replacement

At other times, it makes more sense to replace the turbocharger rather than repair it. Here are the circumstances that favour turbo replacement versus repair:

Severe Turbo Damage

If there are extensive internal damage (broken shaft, burnt out compressor wheel, etc.), it is often less expensive to replace the turbo versus the cost to repair it.The cost of repairing a turbo is often cheaper than buying all the parts and hiring the expertise necessary for a full fix.

High-Mileage Turbo

The truck’s turbo, if it is an old one, has probably exceeded its life expectancy. Once a turbo has been around the block for a while, the expected amount of general wear has likely been exceeded, and regardless of whether you repair one problem, another will likely be there to crop up soon. Replacing a failing turbo with a new or remanufactured unit might offer more long-term reliability.

Performance Upgrades

Replacing the turbo with a more powerful or more effective unit can give a significant performance advantage, and performance upgrades typically involve a full replacement because the existing turbo is almost certainly not capable of supporting the higher boost pressure, or higher airflow rates, required for high-performance use.

Cost Considerations

The best option you are recommended is to look out the extent of the damage then compare the cost and get what works in your financial plan .

You could get an estimate of turbo prices from 250 dollers to 1700 dollar depending on how

Extent of the damage, Type of your vehicle and the affordability of the prices of parts, If you are willing to go for repair you are saving on money. Below is a breakdown on the cost of turbo repair compared to replacement.

Typical turbo repair price: A turbo replacement usually costs $400-$1,000, depending on how much needs to be replaced, and if it’s a seal or bearings that’s been damaged. If there’s damage that needs repair, fixing the turbo will often cost less than replacing it.

Turbo Replacement: To replace a full turbocharger assembly – including piping, electrical connections and any compressor shrouds or intercooler end-tanks, the cost moves into the $1,000-$3,000 or more range (on most passenger cars); higher for high-performance or aftermarket turbos. A new unit can provide a whole new chapter in longevity and durability. If the original unit has significant wear or a history of problems, getting this may be a very good idea.

Conclusion

If there’s just minor damage, or you’re on a tight budget, a turbo repair can be sufficient. If the damage is too severe, or you want to improve the performance of the whole engine, a turbo supplier can help with a turbo replacement. By carefully assessing the condition of your turbo and balancing the costs of a turbo repair versus other options, you can make the right choice to keep your car running smoothly.
