The Nissan R34 GT-R is an iconic vehicle known for its performance and tuning potential. Achieving over 700 horsepower from this legendary car requires significant upgrades to its internal components and supporting modifications. In this article, we will explore the essential upgrades needed to reach this performance milestone while maintaining reliability.
Understanding the R34 GT-R Engine
The heart of the R34 GT-R is the RB26DETT engine, a 2.6-liter inline-six twin-turbocharged powerhouse. To achieve 700+ horsepower, it’s crucial to understand the engine’s design and limitations. The RB26 is known for its robust construction, but certain components must be upgraded to handle increased power levels.
Upgrading Internal Components
Pistons and Rods
One of the first upgrades should be the pistons and connecting rods. Stock components are not designed to withstand the stress of 700+ horsepower. Consider the following options:
- Forged Pistons: These provide increased strength and durability.
- Forged Connecting Rods: Necessary for handling higher RPMs and power levels.
Crankshaft
While the stock crankshaft can handle moderate power increases, for 700+ horsepower, a forged crankshaft is recommended. This upgrade ensures that the engine can handle the additional stress without failure.
Camshafts
Upgrading to performance camshafts can significantly improve airflow and overall engine efficiency. Look for camshafts designed for high horsepower applications that provide a good balance of lift and duration.
Supporting Mods for Maximum Performance
Turbochargers
The stock turbochargers will likely not suffice for 700+ horsepower. Upgrading to larger, high-performance turbochargers is essential. Consider the following:
- Single Turbo Conversion: A single large turbo can provide more power and efficiency.
- Upgraded Twin Turbos: Larger twin turbos can also be effective for maintaining balance and power delivery.
Fuel System Upgrades
To support increased horsepower, the fuel system must be upgraded. This includes:
- High-Flow Fuel Injectors: Essential for delivering the necessary fuel volume.
- Upgraded Fuel Pump: A high-capacity fuel pump ensures adequate fuel delivery under high demand.
- Fuel Pressure Regulator: Helps maintain consistent fuel pressure across the system.
Cooling System Enhancements
With increased power comes increased heat. Upgrading the cooling system is crucial to maintain optimal engine temperatures. Consider:
- Upgraded Radiator: A larger radiator can improve cooling efficiency.
- Intercooler Upgrade: A high-performance intercooler reduces intake temperatures, enhancing performance.
Exhaust System
An upgraded exhaust system is vital for improving airflow and reducing back pressure. Options include:
- High-Flow Catalytic Converter: Improves exhaust flow while remaining street legal.
- Performance Exhaust System: A full cat-back exhaust system enhances sound and performance.
Tuning for Performance
After all upgrades are complete, proper tuning is essential to achieve and maintain 700+ horsepower. A professional tune ensures that the engine runs efficiently and reliably. Consider using a standalone engine management system for optimal control over fuel and ignition settings.
Conclusion
Achieving 700+ horsepower in an R34 GT-R is an ambitious yet rewarding endeavor. By upgrading internal components and implementing supporting modifications, owners can unlock the full potential of this legendary vehicle. Always prioritize quality parts and professional installation to ensure reliability and performance.
