Top Precision Turbos for Nissan GT-R R35
Precision 6266 Turbocharger
The Precision 6266 turbocharger is a popular choice among GT-R enthusiasts. It offers a good balance between spool time and peak power. With a 66mm compressor wheel and a 62mm turbine wheel, this turbo can support power levels up to 800 horsepower. Its quick spool characteristics make it suitable for both street and track applications.
Precision 6466 Turbocharger
For those looking for even more power, the Precision 6466 turbocharger is an excellent option. This turbo features a larger compressor wheel, allowing it to support power levels exceeding 1000 horsepower. While it may have slightly slower spool characteristics compared to the 6266, its performance in high RPM situations is unmatched.
Precision 6870 Turbocharger
The Precision 6870 turbocharger is designed for serious performance builds. With a 68mm compressor and a 70mm turbine wheel, it provides exceptional airflow and power delivery. Capable of supporting over 1200 horsepower, this turbo is ideal for those who want to push their GT-R to the limits.
Performance Analysis
When evaluating the performance of these turbos on the Nissan GT-R R35, several key metrics should be considered:
- Boost pressure
- Power band
- Throttle response
- Heat management
Boost Pressure
Boost pressure is a critical factor in determining the performance of a turbocharger. Each of the turbos mentioned can achieve high boost levels, but the efficiency at which they do so varies. The 6266 provides quick boost response, while the 6466 and 6870 offer higher peak pressures at the expense of some spool time.
Power Band
The power band of each turbo affects how the GT-R feels during acceleration. The 6266 turbo produces a broad power band, making it ideal for daily driving. In contrast, the 6466 and 6870 turbos excel in high RPM ranges, providing exhilarating performance for track use.
Throttle Response
Throttle response is essential for a performance vehicle like the GT-R R35. The 6266 turbo is known for its immediate response, allowing drivers to feel connected to the power delivery. The larger turbos may experience some lag but compensate with increased power at higher RPMs.
Heat Management
Heat management is crucial when running high-performance turbos. Precision turbos are designed to handle high temperatures effectively, but additional cooling solutions may be necessary, especially with the 6466 and 6870 models, which generate more heat due to their increased power output.
Installation Considerations
Installing a precision turbocharger on a Nissan GT-R R35 involves several considerations:
- Upgraded fuel system
- ECU tuning
- Exhaust system modifications
- Intercooler upgrades
Upgraded Fuel System
To support the increased power levels from a new turbo, an upgraded fuel system is essential. This includes larger fuel injectors and a higher capacity fuel pump to ensure adequate fuel delivery.
ECU Tuning
Proper ECU tuning is critical to optimize performance and reliability. A professional tune will adjust fuel maps, ignition timing, and boost levels to match the new turbo’s characteristics.
Exhaust System Modifications
Upgrading the exhaust system can help reduce back pressure and improve turbo efficiency. A high-flow exhaust system is recommended when installing a larger turbo.
Intercooler Upgrades
An upgraded intercooler is vital for managing the increased heat generated by a high-performance turbo. A larger intercooler will help maintain optimal intake temperatures, improving performance and reliability.
Conclusion
Choosing the best precision turbo for your Nissan GT-R R35 can significantly impact its performance. The Precision 6266, 6466, and 6870 turbos each offer unique advantages, catering to different performance goals. By considering factors such as boost response, power band, and installation requirements, you can make an informed decision that enhances your driving experience.
