The Toyota 2JZ-GTE engine is renowned for its robust build and impressive tuning potential. Among the various modifications enthusiasts pursue, upgrading the turbocharger is one of the most impactful. In this article, we will explore two of the best turbo combos for the 2JZ-GTE: the Garrett GTX3584RS and the Precision 6466. These turbochargers are popular choices for those seeking maximum power and performance.
Understanding the 2JZ-GTE Engine
The 2JZ-GTE is a 3.0-liter inline-six engine that features a dual overhead cam design and a robust iron block. It was originally designed for the Toyota Supra MK4, but its applications have expanded into various performance builds. With a strong aftermarket support system, the 2JZ-GTE can handle significant power increases, making it a favorite among tuners.
Why Upgrade the Turbo?
Upgrading the turbocharger is essential for achieving higher horsepower and torque figures. A larger turbo can provide more airflow, which translates to increased power output. However, the choice of turbo must match the engine’s characteristics and the intended use of the vehicle. Below, we will examine two leading options for the 2JZ-GTE.
Garrett GTX3584RS Turbocharger
The Garrett GTX3584RS is a popular choice among 2JZ-GTE enthusiasts for its ability to provide a balance of power and responsiveness. It features a 76mm inducer and is designed to support power levels up to 800 horsepower.
Key Features
- High-efficiency compressor wheel for improved airflow.
- Ball bearing design for quicker spool times.
- Lightweight construction to reduce turbo lag.
The GTX3584RS is known for its broad power band, making it suitable for both street and track applications. Its ability to spool quickly allows for a more responsive throttle, enhancing the driving experience.
Precision 6466 Turbocharger
The Precision 6466 turbocharger is another excellent option for those looking to maximize power from their 2JZ-GTE. With a 66mm inducer, this turbo is designed for high-performance applications and can support power levels exceeding 800 horsepower.
Key Features
- Large compressor housing for optimal airflow.
