Understanding the Garrett GT2871R Turbocharger
The Garrett GT2871R is a popular choice among tuners due to its ability to produce significant power while maintaining good response. Here are some key features of this turbocharger:
- Compressor Wheel: 71mm
- Turbine Wheel: 64mm
- Optimal Boost Range: 1.0 to 1.5 bar
- Power Output: Up to 400 HP
With the right supporting modifications, the GT2871R can transform the 350Z’s performance, making it an ideal choice for a Stage 2 build.
Supporting Modifications for the Stage 2 Build
To achieve 400 horsepower with the Garrett GT2871R, several supporting modifications are necessary. These components work together to ensure the engine can handle the increased power and boost levels.
1. Upgraded Fuel System
An upgraded fuel system is crucial for meeting the increased fuel demands of a turbocharged engine. Key components include:
- High-Flow Fuel Injectors: 750cc or larger
- Upgraded Fuel Pump: Capable of supporting higher flow rates
- Fuel Pressure Regulator: To maintain consistent pressure
2. Exhaust System
A free-flowing exhaust system is essential for maximizing turbo efficiency. Consider the following upgrades:
- Turbo-Back Exhaust: Includes a high-flow catalytic converter
- Headers: Aftermarket headers to reduce back pressure
- Exhaust Tips: Larger diameter tips for better flow
3. Intercooler Upgrade
Installing a high-performance intercooler helps reduce intake temperatures, improving engine efficiency and power output. Look for:
- Front-Mount Intercooler: Larger core for better heat dissipation
- Intercooler Piping: Upgraded piping to reduce restrictions
4. Engine Management
Proper engine management is critical for tuning the vehicle to handle the additional power. Options include:
- Standalone ECU: Provides full control over tuning parameters
- Reflash or Piggyback System: For those looking to retain the stock ECU
5. Internal Engine Components
While the stock internals can handle moderate power levels, upgrading certain components can provide added reliability:
- Forged Pistons: To withstand higher boost levels
- Upgraded Rods: For improved strength and durability
- Performance Camshafts: To optimize airflow
Tuning for Maximum Performance
After installing the necessary components, proper tuning is essential to ensure the engine runs smoothly and efficiently. A professional tuner can optimize the fuel maps and ignition timing to extract the best performance from your setup.
Conclusion
The Stage 2 turbo build with the Garrett GT2871R turbocharger is an excellent way to unlock the full potential of the Nissan 350Z. By investing in the right supporting modifications and ensuring proper tuning, achieving 400 horsepower is not only possible but also reliable. This setup offers a thrilling driving experience while maintaining the integrity of the vehicle.
