The Toyota Supra has long been a favorite among car enthusiasts, known for its impressive performance and tuning potential. One of the most significant upgrades that owners consider is the replacement of the factory throttle bodies with Tomei Individual Throttle Bodies (ITBs). In this article, we will compare the performance and cost of Tomei ITBs against the OEM throttle bodies to help you make an informed decision.
Understanding Individual Throttle Bodies
Individual throttle bodies are designed to improve the engine’s airflow and responsiveness. Unlike the OEM setup, which uses a single throttle body for multiple cylinders, ITBs allow each cylinder to have its own throttle body. This design can lead to several performance benefits, including:
- Improved throttle response
- Increased horsepower and torque
- Better tuning flexibility
Performance Comparison
When considering performance, it’s essential to look at various factors, including horsepower gains, torque delivery, and overall driving experience. Here’s a breakdown of how Tomei ITBs compare to the OEM throttle bodies.
Horsepower Gains
Tomei ITBs have been shown to provide significant horsepower gains over the OEM throttle bodies. On average, users report an increase of:
- 15-30 additional horsepower
- Improved peak power delivery
Torque Delivery
In addition to horsepower, torque is a critical aspect of performance. Tomei ITBs can enhance torque delivery across the RPM range, providing a more enjoyable driving experience. Key benefits include:
- Improved low-end torque
- Smoother power band
Cost Comparison
While performance is crucial, cost is another significant factor when deciding between Tomei ITBs and OEM throttle bodies. Here’s a breakdown of the costs associated with each option:
OEM Throttle Bodies
The cost of OEM throttle bodies can vary based on the model year and availability. On average, you can expect to pay:
- Approximately $300-$500 for a set
- Installation costs if not DIY
Tomei Individual Throttle Bodies
Tomei ITBs typically come at a higher price point due to their performance benefits and engineering. The average cost is:
- Approximately $1,200-$1,500 for a complete set
- Additional installation and tuning costs
Installation and Tuning Considerations
Installing Tomei ITBs is more complex than replacing OEM throttle bodies. It often requires additional modifications and tuning to achieve optimal performance. Here are some key points to consider:
- Professional installation recommended
- ECU tuning necessary for optimal performance
- Potential need for additional components (e.g., intake manifold, fuel system upgrades)
Conclusion
In summary, upgrading to Tomei Individual Throttle Bodies can offer significant performance improvements over OEM throttle bodies for the Toyota Supra. While the cost is higher, the potential gains in horsepower and torque, along with the enhanced driving experience, make it a worthwhile investment for serious enthusiasts. Ultimately, the decision will depend on your performance goals, budget, and willingness to invest in the necessary modifications and tuning.
