The Nissan R33 GT-R is a beloved icon among car enthusiasts, known for its impressive performance and tuning potential. One of the most significant upgrades you can make to this powerhouse is enhancing its turbocharger. This article will explore cost-effective turbo upgrades, specifically transitioning from the Garrett GT28 to the GT35, and achieving over 500 horsepower.
Understanding the Garrett Turbocharger Series
The Garrett turbocharger series has long been favored in the performance tuning community for its reliability and efficiency. The GT28 and GT35 are two popular options for the R33 GT-R, each offering unique benefits and performance characteristics.
Garrett GT28 Turbocharger
The GT28 is a smaller turbocharger, ideal for those who want a quick spool and responsive power delivery. It is a great choice for street applications and provides a good balance of performance and drivability.
- Quick spool time
- Responsive power delivery
- Ideal for lower horsepower applications (up to 450 HP)
Garrett GT35 Turbocharger
On the other hand, the GT35 is designed for higher horsepower applications, making it a popular choice for those looking to push their R33 GT-R beyond 500 HP. While it may have a slightly slower spool time compared to the GT28, the increased power potential is well worth it.
- High horsepower potential (500+ HP)
- Suitable for track and performance applications
- More lag compared to GT28, but greater top-end power
Cost-Effective Upgrade Path
Upgrading from the GT28 to the GT35 can be done without breaking the bank. Here are some cost-effective strategies to consider:
- Turbo Swap: Purchase a used or refurbished GT35 to save on costs.
- Supporting Mods: Invest in supporting modifications like upgraded injectors, a high-flow fuel pump, and an intercooler to maximize performance.
- DIY Installation: If you have mechanical skills, consider installing the turbo yourself to save on labor costs.
Supporting Modifications for Maximum Performance
To fully utilize the potential of the GT35 turbocharger, certain supporting modifications are essential. Here are some key upgrades to consider:
- Fuel System Upgrades: Upgrading to larger fuel injectors (around 750cc) and a high-flow fuel pump will ensure your engine receives enough fuel.
- Intercooler Upgrade: A larger intercooler will help reduce intake temperatures, improving performance and reliability.
- Exhaust System: A free-flowing exhaust system will minimize back pressure, allowing the turbo to spool more efficiently.
- ECU Tuning: Proper tuning is critical to ensure the engine runs smoothly and efficiently with the new turbo setup.
Installation Process
Installing a new turbocharger can be a complex process. Here’s a brief overview of the steps involved:
- Preparation: Gather all necessary tools and parts before starting the installation.
- Remove the Old Turbo: Disconnect the turbo from the exhaust manifold, intake, and oil lines.
- Install the New Turbo: Fit the GT35 turbocharger in place and reconnect all lines and components.
- Check for Leaks: After installation, start the engine and check for any oil or boost leaks.
Tuning for Performance
Once the turbo is installed, proper tuning is essential to achieve optimal performance. A professional tuner can help you set the right air-fuel ratios and timing to ensure your R33 GT-R runs smoothly and efficiently.
Conclusion
Upgrading from a Garrett GT28 to a GT35 turbocharger can significantly enhance the performance of your R33 GT-R, allowing you to reach over 500 horsepower. By following a cost-effective upgrade path and ensuring you have the right supporting modifications, you can enjoy increased power and performance without overspending.
