The Mazda RX-7 is a legendary sports car known for its lightweight design and rotary engine. One of the most effective modifications for enhancing its performance is the installation of a Greddy intercooler. This article will guide you through the costs, steps, and performance benefits of installing a Greddy intercooler on your RX-7.
Understanding Intercoolers
An intercooler is a heat exchanger that cools the air entering the engine after it has been compressed by the turbocharger. Cooler air is denser, allowing for more oxygen and fuel to enter the combustion chamber, which can significantly improve engine performance.
Cost of a Greddy Intercooler
The cost of a Greddy intercooler can vary based on the model and where you purchase it. Here’s a breakdown of potential costs:
- Greddy Intercooler Kit: $600 – $1,200
- Installation Costs (if not DIY): $200 – $500
- Additional Parts (hoses, clamps): $50 – $150
Overall, you can expect to spend between $850 and $1,850 for the entire installation, depending on whether you do it yourself or hire a professional.
Steps to Install a Greddy Intercooler
Preparation
Before starting the installation, gather all necessary tools and parts:
- Greddy intercooler kit
- Socket set
- Wrenches
- Hose clamps
- Cutting tool (if necessary)
- Safety glasses
- Gloves
Ensure your RX-7 is parked on a flat surface and the engine is cool before beginning.
Step 1: Remove the Old Intercooler
Start by disconnecting the battery. Then, remove the intake pipes connected to the old intercooler. Unscrew the mounting bolts and carefully take out the old intercooler.
Step 2: Prepare the New Intercooler
Unbox the Greddy intercooler and check for any damage. If you need to modify any pipes for fitment, use the cutting tool carefully to ensure a snug fit.
Step 3: Install the New Intercooler
Position the Greddy intercooler in place, ensuring it aligns with the mounting points. Secure it with the mounting bolts provided in the kit. Reconnect the intake pipes, ensuring all connections are tight.
Step 4: Reconnect the Battery
Once everything is securely in place, reconnect the battery. Double-check all connections and fittings to ensure there are no leaks.
Step 5: Test Drive
Take your RX-7 for a test drive. Monitor the performance and check for any signs of issues. If everything is functioning properly, you have successfully installed your Greddy intercooler!
Performance Benefits of a Greddy Intercooler
Installing a Greddy intercooler on your Mazda RX-7 offers several performance benefits:
- Increased Horsepower: Cooler intake air leads to more power output from the engine.
- Improved Engine Efficiency: A more efficient combustion process results in better fuel economy.
- Enhanced Turbo Performance: Reduces the risk of heat soak, allowing the turbo to perform optimally.
- Better Reliability: Reduces the chances of engine knock and overheating.
Overall, the installation of a Greddy intercooler is a worthwhile investment for any RX-7 enthusiast looking to enhance their vehicle’s performance.
Conclusion
Installing a Greddy intercooler on your Mazda RX-7 can significantly improve its performance and reliability. While the upfront costs may seem high, the benefits in horsepower and efficiency make it a valuable upgrade.
