History of the BMW B58 Engine

The BMW B58 engine is a 3.0-liter turbocharged straight-six cylinder petrol engine, first entering production in 2015 for the F30 340i. It is part of the new modular BMW engine family - the B series - which includes three, four and six-cylinder variants. The B58 replaced the N55 which had been in production since 2009 and had problems such as valve cover gasket, coolant temp, fuel pump, and oil filter housing.

Since its introduction, the B58 has been used in a variety of BMW models, including the X4M40i and Z4M40i.

It has also seen upgrades over the years with various different variants being released. The most powerful version to date is the S58 engine, found in the BMW M3 and M4.

Most recently, BMW has started using the B58 in the new Toyota Supra. The BMW's engine is tuned to produce 335hp and 500 Nm of torque, giving great performance while retaining fuel efficiency.

It provides a perfect balance between power and practicality for drivers who don't need the full blown performance of the S58 with twin turbos.

The BMW B58 engine is an impressive example of modern engineering, offering great factory performance and efficiency across a range of different vehicles. With its use in the new Supra, the engine's popularity is sure to continue for years to come.

BMW B58 Engine Mods & Tuning

When it comes to BMW B58 engine mods and tuning, there are a few parts that can be upgraded or replaced to improve performance.

Exhaust and intake:

Upgrading your exhaust and intake can not only reduce backpressure, but also increase horsepower by improving the flow of air into the engine.

Cold air intakes are a popular upgrade as they provide cooler, denser air to the engine for improved combustion.

Bigger turbo:

One of the most popular modifications for the BMW B58 engine is installing a bigger turbo. This will increase airflow, resulting in improved power and torque output.

It’s important to do your research and choose the right turbo size for your needs as too small a turbo can lead to poor performance while too big can cause lag or even damage the engine.

ECU tuning:

Using ECU tuning software to reprogram the engine’s electronic control unit (ECU) is another popular performance upgrade for BMW B58 engines.

This allows you to adjust settings such as ignition timing, fuel mapping and boost pressure to optimize performance.

It can also be used to remove the speed limiter, allowing your car to reach higher speeds.

ECU tuning should be done by experienced professionals to ensure the best results and to prevent any damage from occurring.


Installing a downpipe is another popular mod for the BMW B58 engine as it improves exhaust flow, allowing more power to be generated.

Downpipes also reduce backpressure from the turbo and can make your turbo engines sound louder and more aggressive.


Upgrading your fuel injectors to larger-capacity ones can improve the amount of fuel that can be injected into the engine, resulting in improved performance.

It’s important to ensure that the injectors you choose are compatible with your engine block and that they provide a good flow rate without any blockages or issues.

Camshaft upgrade:

Finally, upgrading your camshaft can also provide a boost in performance.

Camshafts control the opening and closing of the intake and exhaust valves and by installing a higher-performance camshaft you can increase the amount of air that enters the engine.

This will result in improved power output from your B58 engine.

Overall, there are a variety of modifications and tuning options available for the BMW B58 and other BMW engines that can improve performance, power and torque output.

It’s important to do your research and speak to experienced professionals before attempting any modifications or tuning as this will help to ensure the best results and avoid any potential damage.

Common Problems of the BMW B58 Engine

The BMW B58 engine is a powerful and reliable engine with many features that make it attractive to drivers.

However, as with any vehicle component, there are some common issues that can arise due to everyday engine wear and tear or other factors.

Here are some of the most common problems associated with the BMW B58 engine:

1.Cooling system:

A key component of any engine bay, the cooling system can fail in a B58 engine due to lack of regular maintenance or buildup of debris.

This can lead to overheating and potential damage to other parts.

2. Vanos system failure:

The Variable Camshaft Timing (Vanos) system is responsible for changing the timing of the camshaft according to driving conditions.

If this system fails, the engine will not be able to run properly and can cause stalling or poor performance.

It happens due to a lack of regular maintenance or a defect in the Vanos system itself.

3. Pcv valve:

The Positive Crankcase Ventilation (PCV) valve is a key part of the engine’s emissions system, and failure can cause a variety of issues for drivers.

This includes problems with acceleration, rough idle, and poor fuel economy.

Fortunately, most of these problems can be easily fixed or prevented with regular maintenance and servicing. It’s important to get your modern turbo BMW engines checked regularly so that any potential issues can be identified and repaired before they become more serious.

It also helps to use quality parts and fluids when making repairs or modifications, as these will ensure the best performance from your engine.
