The RB20DET engine, a 2.0L inline-six turbocharged powerhouse, is known for its potential in the tuning community. Many enthusiasts have successfully modified their RB20DET engines to achieve impressive power outputs, ranging from 280 to 320 horsepower. In this article, we will explore real-world owner reports on various upgrades and modifications that have led to these performance gains.
Understanding the RB20DET Engine
The RB20DET is part of Nissan’s RB family of engines, which are celebrated for their robust design and tuning potential. Originally found in models like the Nissan Skyline and the Nissan Laurel, the RB20DET features an iron block and aluminum DOHC cylinder head. This engine is favored for its ability to handle significant power increases with the right modifications.
Common Upgrades for 280-320 HP Builds
- Upgraded Turbocharger
- Performance Intercooler
- High-Flow Fuel Injectors
- Aftermarket Engine Management
- Upgraded Exhaust System
Upgraded Turbocharger
One of the most significant upgrades for increasing power in the RB20DET is the turbocharger. Many owners report switching to larger turbo options, such as the Garrett GT28 or similar models, which provide a substantial boost in horsepower. These turbos can help achieve quicker spool times and higher boost levels, essential for reaching the desired power output.
Performance Intercooler
To maximize the benefits of a larger turbo, upgrading the intercooler is crucial. A performance intercooler helps lower intake temperatures, improving air density and combustion efficiency. Many RB20DET owners have reported noticeable gains in horsepower and throttle response after installing a front-mount intercooler.
High-Flow Fuel Injectors
As power levels increase, so does the demand for fuel. Upgrading to high-flow fuel injectors ensures that the engine receives the necessary amount of fuel to match the increased air intake. Many enthusiasts opt for 550cc or 740cc injectors, which have proven effective in supporting 280-320 HP builds.
Aftermarket Engine Management
Proper tuning is essential for any modified engine. Many RB20DET owners turn to aftermarket engine management systems, such as the AEM EMS or Link G4, to control fuel maps, ignition timing, and boost levels. These systems allow for precise tuning, ensuring that the engine runs efficiently and reliably at higher power levels.
Upgraded Exhaust System
An upgraded exhaust system not only improves performance but also enhances the engine’s sound. Many owners report gains in horsepower after installing a high-flow cat-back exhaust or a turbo-back system. These upgrades help reduce back pressure and improve exhaust flow, crucial for maximizing turbo efficiency.
Owner Reports and Experiences
To provide insights into the real-world performance of RB20DET upgrades, we gathered reports from several owners who have successfully built their engines to achieve 280-320 horsepower. Here are some key takeaways from their experiences.
