The Subaru WRX is a popular choice among car enthusiasts, particularly for those who enjoy both daily driving and track performance. One of the most critical decisions for WRX owners is whether to stick with the original equipment manufacturer (OEM) engine or invest in a built engine. This article will compare the cost and performance of a WRX built engine versus an OEM engine for daily and track use.
Understanding OEM Engines
OEM engines are designed and manufactured by Subaru, ensuring compatibility and reliability. They are built to meet specific performance standards and are generally more straightforward to maintain.
Advantages of OEM Engines
Choosing an OEM engine has several advantages:
- Reliability: OEM engines are tested for durability and performance.
- Warranty: Typically come with a warranty, providing peace of mind.
- Compatibility: Designed specifically for the WRX, ensuring a perfect fit.
- Resale Value: Maintains higher resale value due to original parts.
Disadvantages of OEM Engines
Despite their advantages, OEM engines also have some drawbacks:
- Performance Limitations: May not meet the demands of high-performance enthusiasts.
- Cost: OEM parts can be expensive, especially for high-performance models.
- Customization: Limited options for upgrades and modifications.
Exploring Built Engines
A built engine is customized and modified to enhance performance, often by aftermarket companies or experienced mechanics. These engines can be tailored to meet specific performance goals, whether for daily driving or track use.
Advantages of Built Engines
Built engines offer several benefits that can appeal to performance enthusiasts:
- Performance Customization: Can be tailored to specific power and torque goals.
- Enhanced Durability: Often built with high-performance components that can withstand more stress.
- Upgradability: Easier to modify and upgrade as performance needs change.
- Unique Builds: Allows for a more personalized driving experience.
Disadvantages of Built Engines
However, built engines also come with their own set of challenges:
- Higher Initial Cost: Often more expensive than OEM options due to custom work.
- Reliability Concerns: May not be as reliable as OEM engines if not built properly.
- Warranty Issues: Typically do not come with warranties, leading to potential repair costs.
- Complex Maintenance: May require specialized knowledge for repairs and maintenance.
Cost Comparison
When considering the cost of a WRX built engine versus an OEM engine, several factors come into play, including the initial purchase price, installation costs, and potential long-term expenses.
OEM Engine Costs
The cost of an OEM engine can vary based on the model year and specific engine type. On average, an OEM engine can range from $3,000 to $7,000, including installation. Additional costs may arise from necessary maintenance or repairs.
Built Engine Costs
Built engines can significantly exceed the cost of OEM engines, depending on the level of customization and components used. A basic built engine may start around $5,000, while high-performance builds can reach $15,000 or more. Installation costs can also add to the overall expense.
Performance Comparison
Performance is a crucial aspect when comparing OEM and built engines. The intended use of the vehicle—daily driving or track racing—will significantly influence performance requirements.
Daily Driving Performance
For daily driving, OEM engines provide a balance of performance and reliability, ensuring a comfortable ride with adequate power. Built engines can enhance daily driving performance but may sacrifice comfort for power.
Track Performance
On the track, built engines typically outperform OEM engines due to their enhanced modifications and tuning. They can deliver higher horsepower and torque, providing a competitive edge in racing scenarios.
Conclusion
Deciding between a WRX built engine and an OEM engine ultimately depends on individual needs and preferences. For those prioritizing reliability and warranty, an OEM engine may be the best choice. In contrast, performance enthusiasts seeking customization and power may find a built engine more appealing. Weighing the costs and benefits of each option can help owners make an informed decision that best suits their driving style and goals.
