Achieving 700 horsepower in an RB engine swap is an exhilarating challenge for automotive enthusiasts. This article provides key modifications and tuning tips to help you reach this impressive power level.
Understanding the RB Engine Platform
The RB engine series, particularly the RB26DETT, is renowned for its performance potential. Originating from Nissan, this inline-six engine is a favorite for swaps due to its robust construction and tuning flexibility.
Essential Modifications for 700 HP
1. Upgraded Turbochargers
To achieve 700 hp, upgrading to larger turbochargers is crucial. Consider the following options:
- Garrett GTX3582R
- HKS GT-RS
These turbos provide the airflow necessary for high horsepower while maintaining efficiency.
2. Fuel System Upgrades
A reliable fuel system is essential for high horsepower builds. Key components include:
- High-flow fuel injectors (1000cc or larger)
- Upgraded fuel pump (e.g., Walbro 450)
- Fuel pressure regulator
These upgrades ensure sufficient fuel delivery under high boost conditions.
3. Engine Internals
Strengthening the engine internals is vital for reliability at high power levels. Consider the following modifications:
- Upgraded pistons (e.g., forged pistons)
- Connecting rods (e.g., forged rods)
- Upgraded crankshaft (if necessary)
These components help withstand the increased stress from higher boost levels.
4. Exhaust System
An efficient exhaust system enhances turbo performance. Consider these upgrades:
- High-flow downpipe
- Cat-back exhaust system
- Performance catalytic converter
These modifications reduce back pressure and improve turbo spool time.
5. Tuning and Engine Management
Proper tuning is critical for achieving and maintaining 700 hp. Key considerations include:
- Standalone engine management system (e.g., AEM, Haltech)
- Dyno tuning to optimize air-fuel ratios
- Boost control settings
Professional tuning ensures the engine runs efficiently and reliably under high power conditions.
Additional Performance Enhancements
1. Cooling System Upgrades
To manage increased heat from high horsepower, upgrade your cooling system with:
- Upgraded radiator
- Performance intercooler
- Oil cooler
These enhancements help maintain optimal operating temperatures during performance driving.
2. Suspension and Drivetrain Modifications
To handle the increased power, consider upgrading your suspension and drivetrain:
- Performance coilovers
- Upgraded sway bars
- Stronger axles and differential
These modifications ensure better handling and traction, essential for high-power applications.
Conclusion
Reaching 700 hp in an RB swap requires careful planning and execution of key modifications. By upgrading essential components and ensuring proper tuning, you can achieve this performance milestone while maintaining reliability.
