The RB20DET engine, a turbocharged inline-six from Nissan, is a popular choice among car enthusiasts looking to increase horsepower. With the right modifications, it is possible to boost the power output from a modest 200 HP to an impressive 350 HP. This article explores various power modifications using trusted brands like HKS, Trust, and Greddy.
Understanding the RB20DET Engine
The RB20DET is part of Nissan’s RB family of engines, known for their robust construction and tuning potential. This engine, originally designed for the Nissan Skyline, features a DOHC design and a factory turbocharger, making it a solid foundation for performance upgrades.
Initial Power Upgrades
Before diving into more extensive modifications, a few initial upgrades can significantly enhance the RB20DET’s performance. These upgrades typically focus on improving airflow and tuning the engine for better efficiency.
- Upgraded Intake System: Replacing the factory air filter with a high-flow unit can increase airflow to the engine.
- Aftermarket Exhaust: A performance exhaust system reduces back pressure and allows for better exhaust flow.
Boosting Power with HKS Components
HKS is renowned for its high-quality performance parts, and several of their components can help achieve significant power gains on the RB20DET.
HKS GT Turbo Kit
One of the most effective ways to increase horsepower is through a turbo upgrade. The HKS GT Turbo Kit provides a larger turbocharger that can handle higher boost levels, resulting in a substantial power increase.
HKS Super Sequential Blow-Off Valve
This blow-off valve helps to reduce turbo lag and improve throttle response by releasing excess pressure when the throttle is closed. This component is essential for maintaining performance during rapid acceleration and gear changes.
Enhancements with Trust Components
Trust, also known as Greddy, offers a variety of performance parts that can complement the RB20DET modifications, especially in terms of tuning and exhaust systems.
Trust/Greddy Intercooler Kit
An upgraded intercooler is vital for reducing intake temperatures, which can enhance performance and reliability. The Trust intercooler kit is designed to provide better cooling efficiency, allowing for higher boost levels without the risk of knock.
Trust/Greddy E-Manage Ultimate
This advanced engine management system allows for precise tuning of fuel and ignition maps, enabling the engine to run optimally with the new modifications. Proper tuning is crucial for maximizing power and ensuring engine longevity.
Maximizing Power with Greddy Components
Greddy parts are often used in high-performance builds, and they offer several components that can help achieve the 350 HP target.
Greddy Exhaust Manifold
A high-performance exhaust manifold can improve exhaust flow significantly. The Greddy manifold is designed to optimize turbo response and overall engine performance.
Greddy Fuel Management System
To support increased horsepower, adequate fuel delivery is essential. The Greddy fuel management system ensures that the engine receives the right amount of fuel, enhancing performance and preventing lean conditions.
Supporting Modifications
In addition to the primary upgrades, several supporting modifications can help ensure that the engine performs reliably at higher power levels.
- Upgraded Fuel Injectors: Larger injectors are necessary to provide the increased fuel flow required for higher power outputs.
- High-Performance Fuel Pump: A fuel pump capable of delivering adequate pressure is crucial for maintaining performance under load.
- Upgraded Ignition System: A stronger ignition system can help ensure complete combustion, maximizing power and efficiency.
Tuning for Optimal Performance
Once all modifications are installed, proper tuning is essential. A professional tune will ensure that the engine runs smoothly, maximizing power output while maintaining reliability.
Conclusion
With the right combination of HKS, Trust, and Greddy components, it is feasible to increase the RB20DET’s power from 200 HP to 350 HP. Each modification plays a critical role in enhancing performance, and careful tuning is necessary to achieve the best results. Enthusiasts looking to maximize their RB20DET should consider these upgrades for a thrilling driving experience.
