The 2JZ engine has earned a legendary status among car enthusiasts and tuners alike. Its robust construction and impressive performance potential make it a prime candidate for turbocharging. In this article, we will explore the process of converting a 2JZ engine to a single turbo setup, specifically focusing on optimizing for 800+ horsepower using the GTX3584RS turbo and ARP fasteners.
Understanding the 2JZ Engine
The 2JZ engine, originally found in the Toyota Supra MK4, is known for its durability and high-revving nature. It features a cast-iron block and aluminum DOHC head, which contribute to its ability to handle significant power increases. Before diving into the turbo conversion, it’s essential to understand the engine’s components and their roles in performance.
- Block: A strong foundation that supports high horsepower.
- Head: Designed for optimal airflow, crucial for turbocharged applications.
- Pistons and Rods: Upgrading these components is often necessary for high power levels.
Choosing the Right Turbo: GTX3584RS
The GTX3584RS turbo is a popular choice among tuners looking to achieve 800+ horsepower. Its advanced design offers improved efficiency and response compared to older turbo models. Here are some key features of the GTX3584RS:
- Compressor Wheel: A larger wheel for increased airflow.
- Ball Bearing Design: Reduces spool time and improves throttle response.
- Durability: Designed to withstand high temperatures and pressures.
Essential Components for Conversion
To successfully convert your 2JZ engine to a single turbo setup, several components must be upgraded or replaced. Below is a list of essential parts needed for the conversion:
- Turbocharger: GTX3584RS.
- ARP Fasteners: For securing critical components.
- Exhaust Manifold: A high-flow manifold to accommodate the turbo.
- Intercooler: To cool the compressed air before it enters the engine.
- Fuel System: Upgraded injectors and fuel pump to support increased power.
- Tuning: A standalone ECU or reflash to optimize engine performance.
Installing the GTX3584RS Turbo
The installation of the GTX3584RS turbo involves several steps, each requiring precision and attention to detail. Here’s a general overview of the installation process:
- Remove the stock twin turbos and accessories.
- Install the new exhaust manifold designed for the single turbo.
- Mount the GTX3584RS turbo to the manifold.
- Connect the wastegate and ensure proper routing of the exhaust.
- Install the intercooler and piping to connect the turbo to the intake.
- Upgrade the fuel system with larger injectors and a high-flow pump.
Using ARP Fasteners
When building an engine for high horsepower applications, the choice of fasteners is crucial. ARP (Automotive Racing Products) fasteners are renowned for their strength and reliability. Here’s why they are recommended:
- Strength: ARP fasteners are made from high-quality materials, providing superior tensile strength.
- Durability: Designed to withstand the rigors of high-performance applications.
- Precision: Engineered for a perfect fit, reducing the risk of failure.
Tuning for Optimal Performance
After the installation of the turbo and supporting components, tuning is vital to achieve the desired performance. Proper tuning ensures that the engine runs efficiently and safely at high horsepower levels. Here are some tuning considerations:
- Fuel Mapping: Adjusting fuel delivery for optimal combustion.
- Ignition Timing: Ensuring the spark occurs at the right moment for maximum power.
- Boost Control: Setting the wastegate to manage boost levels effectively.
Conclusion
Converting a 2JZ engine to a single turbo setup using the GTX3584RS turbo and ARP fasteners is an exciting project that can yield impressive results. With careful planning, quality components, and expert tuning, achieving 800+ horsepower is within reach. Whether you are a seasoned tuner or a newcomer to the scene, this conversion can elevate your vehicle’s performance to new heights.
