The Nissan S13 240SX has long been a favorite among car enthusiasts, especially those who appreciate the thrill of tuning and performance upgrades. In this article, I will share my personal experience with a $1,500 intake and exhaust system upgrade that significantly boosted my S13’s performance. This review will cover the installation process, performance improvements, and overall satisfaction with the modifications.
Why Upgrade the Intake and Exhaust?
Upgrading the intake and exhaust systems is one of the most common modifications for performance cars. These systems play a crucial role in how efficiently the engine breathes, which directly impacts horsepower and torque. For the S13 240SX, enhancing airflow can lead to noticeable improvements in acceleration and throttle response.
The Intake System Upgrade
For my intake upgrade, I chose a high-performance cold air intake system. This type of intake is designed to draw cooler air from outside the engine bay, improving combustion efficiency.
Installation Process
The installation was straightforward, taking about two hours. Here’s a quick rundown of the steps:
- Remove the factory air intake system.
- Install the new intake pipe and filter, ensuring a secure fit.
- Reconnect any sensors and hoses as needed.
- Start the engine and check for leaks.
Performance Improvements
After the installation, I immediately noticed a difference. The engine felt more responsive, and the throttle response was sharper. Acceleration improved significantly, especially in the mid-range RPMs. The sound of the intake was also a pleasant surprise, adding a sporty growl that made driving more enjoyable.
The Exhaust System Upgrade
Next, I turned my attention to the exhaust system. I opted for a cat-back exhaust system that promised to enhance performance while providing a deeper sound.
Installation Process
The exhaust installation was slightly more complex, taking around three hours. Here’s how I tackled it:
- Lift the car and secure it on jack stands.
- Remove the old exhaust system, starting from the rear and working forward.
- Install the new cat-back system, ensuring all connections are tight.
- Lower the car and start the engine to check for any leaks.
Performance Improvements
With the new exhaust system in place, the performance enhancements were even more pronounced. The car felt lighter and more agile, with a noticeable increase in horsepower. The sound was exhilarating, providing a throaty roar that turned heads wherever I went.
Overall Performance Boost
Combining both the intake and exhaust upgrades, I experienced a significant boost in overall performance. The car felt more powerful, responsive, and engaging to drive. The estimated horsepower gain was approximately 20-25 hp, which is substantial for a naturally aspirated engine.
Cost Breakdown
Here’s a quick breakdown of the costs involved in these upgrades:
- Cold Air Intake: $300
- Cat-Back Exhaust System: $1,200
- Installation Costs: $0 (DIY)
Final Thoughts
Overall, the $1,500 investment in the intake and exhaust systems for my S13 240SX was worth every penny. The performance gains were noticeable, and the enhanced sound made driving a more enjoyable experience. For anyone considering similar upgrades, I highly recommend it. Just be sure to do your research and choose quality parts that fit your specific needs.
