These turbos are reliable for high-performance needs. But, they need proper care to work well over time.

Reduced Oil Flow Needs

Ball bearing turbos need less oil to work well. Unlike journal bearing turbos, which need constant oil flow for the shaft, ball bearing turbos use special ball bearings to cut friction. This design lowers oil use, making it easier to maintain.

Tip: If your car has limited oil or you want less strain on the oil system, a ball bearing turbo is a good option.

Here’s why using less oil helps:

• Lower Oil Pressure Needs: Ball bearing turbos don’t need high oil pressure. This reduces the engine oil pump’s workload and boosts engine efficiency.

• Less Heat Transfer: With less oil in the turbo, less heat moves to the oil. This keeps oil cooler, which is better for the engine.

• Simpler Oil System: Cars with ball bearing turbos need fewer oil system changes. This saves time and money during setup.

For example, in high-speed driving, less oil flow stops oil starvation problems. It also lowers the chance of oil leaks, which happen more with high-pressure systems.

Choosing a ball bearing turbo improves performance and makes maintenance easier. It’s a great choice for drivers wanting power and reliability.

Drawbacks of Ball Bearing Turbochargers

Higher Initial Cost

Ball bearing turbos cost more than journal bearing turbos. This is because they use advanced designs and precise engineering. The materials and production methods are expensive, raising the price. If you have a small budget, this might not be the best choice.

For instance, a journal bearing turbo may cost a few hundred dollars. A ball bearing turbo, however, can cost twice as much or more. For casual drivers or those not focused on speed, the extra cost might not be worth it.

More Complex Maintenance Needs

Taking care of a ball bearing turbo is harder than a journal bearing turbo. The design is detailed and needs careful handling. You might need special tools or expert help to maintain it properly.

Skipping maintenance can hurt performance or cause damage. For example, dirty oil or poor lubrication can harm the bearings. Regular oil checks and changes are very important. If you want something easier to maintain, a journal bearing turbo might be better for you.

Risk of Early Failure in Tough Conditions

Ball bearing turbos face tough conditions like high heat and speed. These can make them fail sooner, especially in rough environments.

• Moving parts rubbing together can wear out quickly.

• High speeds and vibrations can strain the bearings.

• Smaller engines with turbos face extra stress, making vibrations worse.

Companies are improving designs to lower vibrations and make them last longer. But without proper care, the bearings can wear out faster. This is especially true for off-road or high-stress driving. Knowing your turbo’s limits can help avoid expensive repairs.

Note: Using good oil and regular maintenance can help prevent early failures.

Limited Availability for Certain Vehicles

Ball bearing turbos don’t fit every car. They are made for specific engines and uses. If your car is older or uncommon, finding one can be hard.

Some cars, like those with small engines or special setups, may not have ball bearing turbo options. This makes upgrading tricky. You might need to change your engine or get a custom turbo, which costs more and is harder to do.

Note: Check if your car can use a ball bearing turbo before buying. Researching first can save money and effort.

Here’s why they aren’t always available:

• Specialized Design: These turbos are often made for racing or high-speed cars. Popular models get priority over rare ones.

• Market Demand: Most cars use journal bearing turbos. This lowers the need for ball bearing ones in some groups.

• Vehicle Age: Older cars may not work with newer ball bearing turbo designs.

If you own a common performance car, you’ll likely find options. But for rare or old cars, custom solutions may be needed.

Tip: Talk to a turbo expert to find the best upgrade for your car. They can help with compatibility and suggest other choices if needed.

Knowing these limits helps you decide wisely. Ball bearing turbos are great, but their fit depends on your car. Always check before spending money on one.
