The B58 engine, known for its robust performance and tuning potential, has garnered a reputation among automotive enthusiasts for its ability to reach impressive power figures. With the right upgrades, achieving over 600 horsepower is not just a dream but a tangible goal. This article delves into the proven upgrades necessary for building a 600+ HP B58, focusing on the Garrett GT2860RS turbo and forged internals.
Understanding the B58 Engine
The B58 is a 3.0-liter inline-six engine produced by BMW, part of their modular engine family. It is known for its smooth power delivery, strong torque characteristics, and impressive tuning capabilities. With a robust design and advanced technology, the B58 can handle significant power upgrades when properly modified.
Key Upgrades for 600+ HP
To achieve over 600 horsepower from the B58, several key upgrades are essential. Each component plays a crucial role in ensuring reliability and performance. Here are the primary upgrades to consider:
- Garrett GT2860RS Turbo
- Forged Internals
- High-Performance Fuel System
- Upgraded Intercooler
- ECU Tuning
Garrett GT2860RS Turbo
The Garrett GT2860RS turbo is a popular choice for B58 builds aiming for high horsepower. Known for its quick spool and ability to support significant power, this turbocharger is an excellent upgrade. It features:
- Ball bearing design for improved response
- High flow capability for increased power

- Upgraded crankshaft for improved durability
Supporting Modifications
In addition to the turbo and internals, several supporting modifications are necessary to ensure the engine runs smoothly and efficiently at high power levels.
- High-Performance Fuel System: Upgraded fuel injectors and fuel pump are essential to meet the increased fuel demands.
- Upgraded Intercooler: A larger intercooler helps keep intake temperatures low, improving performance and reliability.
- ECU Tuning: Proper tuning is critical to maximizing power and ensuring the engine runs efficiently with the new upgrades.
Installation Considerations
When undertaking a build for 600+ HP, careful consideration must be given to the installation of each component. It is advisable to work with experienced professionals to ensure that all parts are installed correctly and that the engine is tuned properly.
Choosing the Right Shop
Selecting a reputable shop with experience in B58 builds is crucial. Look for the following:
- Experience with turbo installations
- Knowledge of BMW engines
- Positive customer reviews
Conclusion
Building a 600+ HP B58 is an achievable goal with the right upgrades and careful planning. The combination of the Garrett GT2860RS turbo and forged internals provides a solid foundation for high-performance builds. Remember to consider supporting modifications and choose a skilled installation shop to ensure your build is successful.
