The Toyota Supra is a legendary sports car known for its performance and tuning potential. Upgrading the fuel pump is a critical step in enhancing its power, especially when considering injector upgrades. This article will explore the cost and power gains associated with upgrading your Toyota Supra’s fuel pump from 440cc to 800cc injectors.
Understanding Fuel Injectors
Fuel injectors play a crucial role in the performance of your engine by delivering fuel to the combustion chamber. The size of the injector is measured in cubic centimeters (cc), which indicates the amount of fuel it can deliver per minute. Upgrading from 440cc to 800cc injectors can significantly impact your Supra’s performance.
Benefits of Upgrading to 800cc Injectors
When considering an upgrade to 800cc injectors, several benefits can be expected:
- Increased Fuel Flow: 800cc injectors allow for a higher fuel flow rate, essential for supporting higher horsepower levels.
- Improved Engine Performance: With more fuel available, your engine can produce more power, especially at higher RPMs.
- Better Tuning Options: Larger injectors provide more flexibility in tuning, enabling adjustments for optimal performance.
- Enhanced Throttle Response: Upgraded injectors can improve throttle response, making the driving experience more exhilarating.
Cost of Upgrading Fuel Pump and Injectors
The cost of upgrading your Toyota Supra’s fuel pump and injectors can vary based on several factors, including the brand of parts, labor costs, and whether you choose to do the installation yourself.
Estimated Costs
- Fuel Pump: The cost of a high-performance fuel pump can range from $100 to $300, depending on the brand and specifications.
- Injectors: Upgrading to 800cc injectors typically costs between $600 and $1,200 for a set, depending on the manufacturer.
- Labor Costs: If you choose to have a professional install the parts, expect to pay an additional $200 to $500 for labor.
Installation Process
Installing a new fuel pump and upgrading injectors involves several steps. Here’s a brief overview of the process:
- Preparation: Gather all necessary tools and parts before starting the installation.
- Remove Old Fuel Pump: Disconnect the battery, remove the fuel tank, and take out the old fuel pump.
- Install New Fuel Pump: Install the new high-performance fuel pump and reassemble the fuel tank.
- Replace Injectors: Remove the old injectors and replace them with the new 800cc injectors.
- Reassemble and Test: Reassemble any components removed during installation and test the system for leaks and performance.
Power Gains from Upgrading
Upgrading to 800cc injectors can lead to substantial power gains, especially when paired with other performance modifications. Here’s what you can expect:
- Horsepower Increase: Depending on your setup, you can see power gains ranging from 50 to 150 horsepower.
- Torque Improvements: Upgraded injectors can also enhance torque, providing better acceleration.
- Performance at Higher RPMs: Larger injectors allow for sustained power at higher RPMs, improving overall driving dynamics.
Conclusion
Upgrading your Toyota Supra’s fuel pump and injectors is a worthwhile investment for anyone looking to enhance their vehicle’s performance. With the potential for significant power gains and improved throttle response, the transition from 440cc to 800cc injectors can transform your driving experience. Consider the costs and installation process carefully, and enjoy the thrill of increased power on the road.
