The Toyota 2JZ engine is renowned for its durability and performance potential, making it a favorite among tuners and enthusiasts. Achieving 700 horsepower with a fully built 2JZ requires careful selection of components, particularly pistons, rods, and head components. This article will guide you through the best options available for each of these critical engine parts.
Understanding the 2JZ Engine
The 2JZ engine, particularly the 2JZ-GTE variant, is a 3.0-liter inline-six engine that has gained a cult following due to its robust design and impressive tuning capabilities. Originally found in the Toyota Supra, it is capable of handling high horsepower levels when built properly.
Key Components for Achieving 700 HP
To reach the 700 HP mark, it is essential to select the right components that can withstand the increased power and stress. The main components to focus on are pistons, connecting rods, and cylinder head components.
Pistons
Pistons play a crucial role in the engine’s performance. When building a 2JZ to handle 700 HP, you need to choose pistons that can withstand high pressures and temperatures. Here are some recommended options:
- CP Pistons: Known for their strength and lightweight design, CP pistons are a popular choice among tuners.
- Wiseco Pistons: These pistons offer excellent durability and are designed for high-performance applications.
- JE Pistons: JE offers custom options that can be tailored to specific boost levels and engine setups.
Connecting Rods
Connecting rods must be able to handle the increased load from higher horsepower. Selecting the right rods is essential for reliability. Consider the following options:
- Carillo Rods: Known for their strength and reliability, Carillo rods are a top choice for high-performance builds.
- Manley Rods: These rods are designed for extreme conditions and can handle high horsepower applications.
- GRP Rods: GRP offers lightweight options that maintain strength, making them suitable for high-revving applications.
Cylinder Head Components
The cylinder head is critical for airflow and overall engine performance. Upgrading the head components is necessary to achieve 700 HP. Key components include:
- Valves: Upgrading to larger valves can improve airflow. Consider titanium valves for reduced weight and increased strength.
- Valve Springs: High-performance valve springs are essential to prevent valve float at high RPMs.
- Cylinder Head Gasket: A multi-layer steel (MLS) gasket is recommended for high boost applications to ensure a proper seal.
Supporting Modifications
In addition to the main components, several supporting modifications are necessary to ensure the engine can handle 700 HP effectively. These include:
- Turbocharger: Upgrading to a larger turbo will provide the necessary airflow to achieve higher horsepower.
- Fuel System: An upgraded fuel pump and injectors are essential to deliver the required fuel for high horsepower levels.
- Engine Management: A standalone engine management system will allow for precise tuning and optimization of the engine.
Conclusion
Achieving 700 HP with a fully built 2JZ engine is an ambitious goal but entirely possible with the right components and modifications. By carefully selecting high-quality pistons, connecting rods, and head components, along with supporting modifications, you can unlock the full potential of the legendary 2JZ engine.
