The SR20DET engine has gained a reputation for its tuning potential and performance capabilities. Among the various modifications available, upgrading the turbocharger is one of the most impactful changes that can be made. In this article, we will compare two popular turbo options: the Garrett GT2871R and the T28. We will explore their specifications, performance gains, and overall suitability for different applications.
Introduction to the SR20DET Engine
The SR20DET is a 2.0-liter inline-four engine produced by Nissan, known for its robust design and turbocharged performance. It has been widely used in various Nissan models, including the 240SX and Silvia. Due to its strong aftermarket support, many enthusiasts seek ways to enhance its power output.
Understanding Turbochargers
Turbochargers play a crucial role in increasing an engine’s power by forcing more air into the combustion chamber. This allows for more fuel to be burned, resulting in greater horsepower and torque. The choice of turbocharger can significantly affect the engine’s performance characteristics.
Garrett GT2871R Overview
The Garrett GT2871R is a popular choice among SR20DET enthusiasts looking for significant power gains. It is known for its ability to provide a broad power band and quick spool time. Here are some key specifications:
- Compressor Wheel: 71mm
- Turbine Wheel: 64mm
- Peak Power: 400+ hp
- Ideal Boost Range: 18-24 psi
Performance Gains with GT2871R
When properly tuned, the GT2871R can provide impressive performance gains. Many users report increases in horsepower ranging from 300 to 400 hp, depending on supporting modifications and tuning. The turbo’s efficiency allows for strong mid-range torque, making it suitable for both street and track applications.
T28 Turbo Overview
The T28 turbo is another well-known option for the SR20DET. Originally equipped on the Nissan Silvia models, it is often seen as a more budget-friendly alternative to larger turbos. Here are some specifications for the T28:
- Compressor Wheel: 60mm
- Turbine Wheel: 53mm
- Peak Power: 300-350 hp
- Ideal Boost Range: 12-18 psi
Performance Gains with T28
The T28 turbo can provide a solid performance upgrade for enthusiasts looking to enhance their SR20DET’s capabilities. Users typically see horsepower gains between 250 and 350 hp. While it may not match the GT2871R in peak power, it offers a more linear power delivery, making it a great choice for daily driving.
Comparative Analysis: GT2871R vs. T28
When deciding between the Garrett GT2871R and the T28, several factors must be considered:
- Power Output: The GT2871R generally provides higher peak power compared to the T28.
- Spool Time: The T28 may spool faster, making it more responsive at lower RPMs.
- Cost: The T28 is usually more affordable, making it accessible for budget builds.
- Application: The GT2871R is better suited for high-performance builds, while the T28 is ideal for street use.
Conclusion
