If you’re a car enthusiast, chances are you’ve heard of the legendary 2JZ engine. Made famous by the Toyota Supra, the 2JZ engine is renowned for its immense tuning potential and has become a popular choice for high-performance race car builds. Whether you’re looking to build a street legal monster or a dedicated track machine, having the right custom 2JZ turbo race car parts is essential for achieving the power, speed, and reliability you need to dominate the competition. In this blog, we’ll explore 9 essential parts to consider when building a custom 2JZ turbo race car, so buckle up and let’s dive in!
1. Turbocharger:
The turbocharger is the heart of any turbocharged engine, and choosing the right one is crucial for achieving the desired power output. There are various sizes and types of turbochargers available, each with its own strengths and limitations. Factors to consider include the size of the compressor and turbine wheels, the A/R ratio, and the compressor map. Selecting the right turbocharger for your specific racing application is crucial to achieving optimal boost levels and power delivery.
2. Fuel System Upgrades:
To support the increased horsepower and boost levels of a custom 2JZ turbo race car, upgrading the fuel system is essential. This may include larger fuel injectors, a high-flow fuel pump, a fuel pressure regulator, and upgraded fuel lines. Proper fuel delivery is critical for ensuring adequate fuel supply and preventing lean conditions that can lead to engine damage.
3. Engine Management System:
An aftermarket engine management system is a must for fine-tuning and controlling the increased power and boost levels of a custom 2JZ turbo race car. A standalone ECU (Engine Control Unit) allows you to adjust and optimize various parameters, such as ignition timing, fuel delivery, boost control, and more. This gives you precise control over your engine’s performance and ensures reliable operation under extreme racing conditions.
4. Intercooler:
An intercooler is an essential part of any turbocharged setup, as it helps to cool the intake air charge before it enters the engine. This denser and cooler air allows for more efficient combustion, resulting in increased horsepower and torque. Upgrading to a larger, more efficient intercooler can help reduce intake air temperatures and improve overall engine performance.
5. Exhaust System:
A high-flow exhaust system is crucial for allowing the engine to breathe properly and optimize turbocharger efficiency. Upgrading to a larger diameter exhaust with minimal restriction, such as a turbo-back or a cat-back system, can help reduce backpressure, improve exhaust flow, and enhance overall performance.
6. Performance Clutch:
A performance clutch is essential for handling the increased power and torque of a custom 2JZ turbo race car. Upgrading to a performance clutch with a higher torque capacity and improved engagement characteristics can help ensure reliable power transfer and prevent clutch slippage, especially during high-performance driving or racing situations.
7. Suspension Upgrades:
A race car needs a suspension system that can handle the increased power and provide optimal handling characteristics. Upgrading to performance-oriented coilovers, sway bars, and control arms can improve stability, cornering, and overall handling performance. Proper suspension setup is critical for keeping the car planted on the track and maximizing performance.
8. Brake Upgrades:
A high-performance race car needs brakes that can handle the increased speeds and provide consistent stopping power. Upgrading to larger, high-performance brake rotors, calipers, and pads can improve braking performance, reduce brake fade, and increase overall safety on the track.
9. Lightweight Wheels and Tires:
Reducing unsprung weight is crucial for improving acceleration.
