The Toyota IS300 is a beloved platform for enthusiasts, especially when paired with the legendary 2JZ-GTE engine. For those looking to push the limits and achieve a reliable 700 horsepower, a solid upgrade plan is essential. This article outlines the top upgrades needed for a successful 700 HP IS300 2JZ-GTE swap using the Garrett GTX3582R turbo.
Understanding the 2JZ-GTE Engine
The 2JZ-GTE engine, known for its robust construction and high-performance capabilities, is an inline-six engine that can handle substantial power upgrades. Its design allows for significant tuning potential, making it a favorite among tuners.
Choosing the Right Turbo: Garrett GTX3582R
The Garrett GTX3582R turbocharger is an excellent choice for those aiming for 700 horsepower. This turbo offers a good balance of spool time and peak power, making it suitable for both street and track applications.
Key Features of the GTX3582R
- Ball bearing design for quicker spool times.
- High flow capabilities for increased power.
- Durable construction to withstand high boost levels.
Essential Upgrades for Achieving 700 HP
1. Fuel System Upgrades
To support 700 horsepower, a robust fuel system is crucial. This includes upgrading the fuel pump, injectors, and fuel lines.
- High-flow fuel pump (e.g., Walbro 450 or similar).
- Upgraded fuel injectors (1000cc or larger recommended).
- AN fittings and lines for improved fuel delivery.
2. Engine Management System
A reliable engine management system (EMS) is vital for tuning and optimizing performance. A standalone ECU will allow for precise control over fuel and timing.
- Standalone ECU (e.g., AEM, Haltech, or MoTeC).
- Wideband O2 sensor for accurate air-fuel ratio monitoring.
- Tuning software for custom maps.
3. Exhaust System
An efficient exhaust system is essential for maximizing turbo performance. Upgrading to a 3-inch downpipe and full exhaust will reduce back pressure and improve flow.
- 3-inch stainless steel downpipe.
- High-flow catalytic converter or test pipe.
- 3-inch cat-back exhaust system.
4. Intercooler Upgrade
To ensure optimal performance, a larger intercooler is necessary to cool the intake air and prevent knock. A front-mount intercooler is typically the best choice.
- Front-mount intercooler with sufficient core size.
- High-flow intercooler piping.
- Quality couplers and clamps for secure connections.
5. Internal Engine Components
While the 2JZ-GTE can handle a lot of power, upgrading internal components can provide added reliability. Consider the following:
- Forged pistons for increased strength.
- Forged connecting rods to handle high power levels.
- Upgraded valve springs and retainers for better high RPM performance.
6. Cooling System Enhancements
A high-performance cooling system is essential to prevent overheating, especially during high-power situations. Upgrading the radiator and adding an oil cooler can help maintain optimal temperatures.
- Upgraded aluminum radiator.
- Oil cooler kit for better oil temperature management.
- High-performance thermostat.
Conclusion
Achieving 700 horsepower in a Toyota IS300 with a 2JZ-GTE swap using a Garrett GTX3582R turbo is an ambitious but rewarding project. By carefully selecting the right upgrades for the fuel system, engine management, exhaust, intercooler, internal components, and cooling system, you can create a reliable and powerful setup that performs well on the street and track.
