The Nissan RB26 engine has long been a favorite among car enthusiasts and tuners, especially for those looking to extract maximum performance from their vehicles. With its robust design and proven reliability, the RB26 is capable of reaching impressive horsepower figures when upgraded with the right components. In this article, we will explore how to upgrade the RB26 turbo system using AMS Performance components to achieve over 800 horsepower.
Understanding the RB26 Engine
The RB26DETT is a 2.6-liter inline-six engine that powered the iconic Nissan Skyline GT-R. Known for its strong internals and twin-turbo setup, the RB26 provides a solid foundation for high-performance builds. Its architecture allows for significant upgrades, making it a popular choice for racing and street performance applications.
Key Components for Upgrading the RB26 Turbo
- Turbochargers
- Intercoolers
- Fuel injectors
- Intake and exhaust systems
- Engine management systems
Turbochargers
Upgrading the turbochargers is one of the most effective ways to increase horsepower. AMS Performance offers a range of turbo options for the RB26, including their high-flow turbo kits that are designed to support over 800 horsepower. These turbochargers provide improved spool times and greater airflow, essential for maximizing power output.
Intercoolers
Cooling the intake air is crucial for maintaining performance and preventing knock. AMS Performance intercoolers are designed to provide efficient cooling, reducing intake temperatures and allowing for more aggressive tuning. A larger intercooler will help support the increased horsepower from upgraded turbochargers.
Fuel Injectors
To achieve over 800 horsepower, the RB26 will require upgraded fuel injectors. AMS Performance provides high-flow injectors that ensure the engine receives the necessary fuel, even at high boost levels. Proper fuel delivery is essential for achieving optimal power and maintaining engine reliability.
Intake and Exhaust Systems
Upgrading the intake and exhaust systems allows for better airflow to and from the engine. AMS Performance offers performance intake manifolds and exhaust systems that reduce restrictions and enhance engine output. A free-flowing exhaust will help improve turbo response and overall horsepower.
Engine Management Systems
With all these upgrades, a proper engine management system is necessary to tune the RB26 effectively. AMS Performance provides standalone engine management solutions that allow for precise tuning of fuel maps, ignition timing, and boost levels. This is critical for achieving the desired horsepower and ensuring engine safety.
Step-by-Step Upgrade Process
Upgrading the RB26 to achieve over 800 horsepower involves several key steps. Below is a general outline of the process:
- Remove the stock turbochargers and exhaust manifold.
- Install AMS Performance turbochargers and associated hardware.
- Upgrade the intercooler and piping.
- Replace stock fuel injectors with high-flow AMS injectors.
- Install a performance intake manifold and exhaust system.
- Connect and configure the engine management system.
- Tune the engine on a dynamometer for optimal performance.
Testing and Tuning
After completing the upgrades, it’s essential to test and tune the vehicle. This process involves running the car on a dynamometer to measure horsepower and torque output. The tuning process ensures that the engine runs efficiently and safely, maximizing performance while minimizing the risk of damage.
Conclusion
Upgrading the RB26 engine with AMS Performance components can transform it into a powerhouse capable of exceeding 800 horsepower. By carefully selecting and installing high-quality parts, enthusiasts can unlock the full potential of this legendary engine. With the right setup, the RB26 can deliver exhilarating performance on the street or the track.
