The Mazda MX-5 Miata NB is a beloved sports car known for its lightweight design and agile handling. One popular modification among enthusiasts is the installation of a catch can, which helps manage engine blow-by gases and can improve performance. This article will delve into the cost, process, and the potential for a 4 horsepower improvement from this modification.
Understanding the Catch Can
A catch can is a device that collects excess oil and gas that escape from the engine’s crankcase. This is particularly important in turbocharged engines, where blow-by gases can be more prevalent. By installing a catch can, you can reduce oil consumption and improve engine performance.
Cost of Installation
The cost of installing a catch can on a Mazda MX-5 Miata NB can vary based on several factors, including the type of catch can you choose and whether you perform the installation yourself or hire a professional. Here’s a breakdown of the potential costs:
- Catch Can: $50 – $200
- Installation Kit: $20 – $50
- Labor (if professional): $50 – $100
Overall, if you decide to do it yourself, you can expect to spend around $70 to $250. If you opt for professional installation, the total cost could range from $120 to $350.
Installation Process
Installing a catch can on your Mazda MX-5 Miata NB is a straightforward process if you follow these steps:
- Gather Tools: You will need basic hand tools, including wrenches, pliers, and possibly a drill.
- Choose Location: Select a suitable location for the catch can. It should be easily accessible for maintenance.
- Disconnect Battery: Safety first! Disconnect the negative terminal of the battery.
- Remove Engine Cover: If applicable, remove the engine cover to access the PCV system.
- Install Fittings: Install the fittings on the catch can according to the manufacturer’s instructions.
- Connect Hoses: Connect the hoses from the engine’s PCV system to the catch can.
- Mount the Catch Can: Securely mount the catch can in the chosen location.
- Reconnect Battery: Reconnect the battery and check for any leaks.
After installation, it’s important to regularly check the catch can for accumulated oil and empty it as needed.
Potential Performance Improvement
One of the main reasons for installing a catch can is the potential performance improvement. Many Mazda MX-5 Miata NB owners report an increase in horsepower, with some estimates suggesting as much as a 4 HP gain. This improvement can be attributed to:
- Reduced Oil Consumption: Less oil in the intake means better combustion efficiency.
- Improved Engine Breathing: A cleaner intake allows the engine to breathe better, enhancing performance.
- Lower Engine Knock: Reducing oil vapor can decrease the chances of engine knock, allowing for more aggressive tuning.
While 4 HP may seem modest, every bit counts in a lightweight sports car like the MX-5 Miata, where performance is key.
Conclusion
Installing a catch can on your Mazda MX-5 Miata NB can be a worthwhile investment for those looking to improve performance and maintain engine health. With a reasonable cost and a simple installation process, it’s an upgrade that many enthusiasts find beneficial. Whether you’re a DIYer or prefer professional help, the potential for a 4 HP improvement makes this modification an exciting option for any Miata owner.
