The RB26 engine, known for its robust performance and tuning potential, has become a favorite among car enthusiasts. Upgrading to 700 horsepower is an exciting journey that involves careful planning and the right components. In this article, we will guide you through the step-by-step RB26 turbo upgrade process using Turbosmart components.
Understanding the RB26 Engine
The RB26DETT is a 2.6-liter inline-six engine that was originally designed for the Nissan Skyline GT-R. With twin turbochargers, it has a reputation for being highly tunable. Before starting your upgrade, it’s essential to understand the engine’s capabilities and limitations.
Choosing the Right Components
For a successful upgrade to 700 hp, selecting high-quality components is crucial. Turbosmart offers a range of products that enhance performance and reliability. Here are the key components you will need:
- Turbosmart wastegate
- Turbosmart blow-off valve
- Upgraded turbochargers
- High-flow fuel injectors
- Upgraded fuel pump
- ECU tuning software
Step 1: Preparing the Engine
Before diving into the upgrade, ensure your engine is in good condition. Perform a compression test to check for any issues. It’s also a good idea to replace worn-out components such as spark plugs and ignition coils.
Step 2: Removing Stock Turbochargers
Begin by removing the stock turbochargers. This process involves disconnecting the intake and exhaust piping, as well as the oil and coolant lines. Make sure to label all connections for easy reinstallation.
Step 3: Installing Upgraded Turbochargers
Once the stock turbos are removed, install the upgraded turbochargers. Ensure a proper fit and secure all bolts. Reconnect the oil and coolant lines, making sure there are no leaks.
Step 4: Installing Turbosmart Wastegate
The Turbosmart wastegate is crucial for controlling boost levels. Follow the manufacturer’s instructions for installation. Position it correctly to avoid boost creep and ensure proper functionality.
Step 5: Adding Turbosmart Blow-off Valve
Install the Turbosmart blow-off valve to manage pressure and prevent compressor surge. This component enhances throttle response and protects your turbochargers. Ensure it is plumbed correctly to the intake system.
Step 6: Upgrading Fuel System
To support the increased horsepower, upgrading the fuel system is essential. Replace the stock fuel pump with a high-flow version and install larger fuel injectors. This will ensure adequate fuel delivery under high boost conditions.
Step 7: ECU Tuning
With all hardware installed, it’s time to tune the ECU. Using tuning software, adjust fuel maps and ignition timing to optimize performance. A professional tuner can help achieve the best results while ensuring engine safety.
Step 8: Testing and Fine-Tuning
After tuning, it’s vital to test the vehicle under various conditions. Monitor boost levels, air-fuel ratios, and engine temperatures. Make adjustments as necessary to ensure reliability and performance.
Conclusion
Upgrading your RB26 to 700 hp is an exciting endeavor that requires careful planning and execution. By using Turbosmart components and following this step-by-step guide, you can achieve impressive performance while maintaining reliability. Always remember to prioritize safety and consult professionals when needed.
