The Nissan R33 GT-R, a legendary figure in the world of performance cars, has captivated enthusiasts since its release. Known for its robust engineering and impressive capabilities, many owners seek to enhance its power output. In this article, we will explore the process of upgrading to Nismo turbos and forged internals, enabling the R33 GT-R to achieve 700+ horsepower.
Understanding the R33 GT-R
The R33 GT-R, produced between 1995 and 1998, is part of Nissan’s iconic Skyline series. With its RB26DETT engine, a 2.6-liter inline-six twin-turbocharged powerhouse, it laid the foundation for a performance legacy. However, as with any performance vehicle, there is always room for improvement.
Why Upgrade to Nismo Turbos?
Nismo, Nissan’s performance division, offers turbocharger upgrades that significantly enhance the R33 GT-R’s performance. Here are some reasons to consider upgrading:
- Increased Boost Pressure: Nismo turbos can handle higher boost levels, translating to more power.
- Better Response: Upgraded turbos provide improved throttle response, enhancing the driving experience.
- Reliability: Nismo components are designed for performance and durability, ensuring longevity under stress.
Choosing the Right Forged Internals
To support the increased power from the upgraded turbos, it’s essential to consider forged internals. Here are the key components to focus on:
- Forged Pistons: These provide better strength and resistance to detonation, crucial for high horsepower builds.
- Forged Connecting Rods: Stronger than stock rods, forged options can handle the increased stress from higher power levels.
- Upgraded Crankshaft: A forged crankshaft can withstand the demands of high horsepower applications, ensuring engine reliability.
Installation Process
Upgrading to Nismo turbos and forged internals is a complex process that requires careful planning and execution. Here’s an overview of the installation process:
- Preparation: Gather all necessary tools and parts. A clean workspace is essential for a successful installation.
- Remove the Engine: Detach the engine from the chassis for easier access to internal components.
- Disassemble the Engine: Carefully remove the cylinder head, oil pan, and other components to access the internals.
- Install Forged Internals: Replace the stock pistons, connecting rods, and crankshaft with forged components.
- Upgrade the Turbochargers: Install the Nismo turbos, ensuring proper fitment and alignment.
- Reassemble the Engine: Carefully put all components back together, following manufacturer specifications.
- Reinstall the Engine: Place the engine back into the chassis and reconnect all necessary components.
- Tuning: A professional tune is crucial to optimize performance and ensure reliability.
Tuning for Maximum Performance
After upgrading the turbos and internals, tuning is essential to unlock the full potential of the R33 GT-R. Here are some tuning considerations:
- ECU Remapping: Adjust the engine control unit (ECU) settings to accommodate the new turbochargers and fuel requirements.
- Fuel System Upgrade: Consider upgrading injectors and fuel pumps to support increased power levels.
- Dyno Testing: Use a dynamometer to measure power output and make necessary adjustments to the tune.
Conclusion
Upgrading the R33 GT-R with Nismo turbos and forged internals is a rewarding endeavor that can yield impressive results. With the right components and careful installation, achieving 700+ horsepower is within reach. Always prioritize quality parts and professional tuning to ensure the best performance and reliability from your upgraded GT-R.
