Bolt-On Ball Bearing Turbo P660 for Subaru WRX STI (08-20): A Comprehensive Analysis

The EJ25 turbocharged engine in Subaru WRX STI models from 2008 to 2020 is known for its power and responsiveness. One popular upgrade for these vehicles is the installation of a ball-bearing turbocharger, such as the P660 model from PLM-Mfg. In this analysis, we will discuss the potential advantages and disadvantages of purchasing this bolt-on turbocharger for your Subaru WRX STI.

1. Increased power: The primary reason for installing a ball-bearing turbocharger is the significant power increase it provides. The P660 model can reportedly deliver up to 450 horsepower at the crankshaft, which results in noticeable improvements in acceleration and top speed.

2. Smoother boost: Ball-bearing turbochargers are known for their smoother and more consistent boost delivery compared to their journal-bearing counterparts. This translates to a more responsive and linear driving experience.

3. Reduced lag: By eliminating the need for oil to lubricate the journal bearings, ball-bearing turbos can provide quicker spool-up times, reducing turbo lag, and improving overall driving performance.

4. Improved durability: Ball-bearing turbos are generally more robust and less prone to failure due to their simpler design, which relies on fewer moving parts. This can lead to extended component life and fewer maintenance requirements.

1. Higher cost: The primary disadvantage of upgrading to a ball-bearing turbocharger like the P660 is the substantial cost involved. The turbocharger itself can cost several thousand dollars, and additional installation and tuning services may also be required.

2. Potential noise increase: Some users report an increase in noise levels with a ball-bearing turbocharger, as the lack of oil between the turbine and compressor wheels can lead to more vibration and noise during operation.

3. Installation complexity: Installing a ball-bearing turbocharger requires specific expertise and tools, as the process can be more intricate than a standard journal-bearing turbo upgrade. This may lead to increased labor costs and potential complications during installation.

4. Potential compatibility issues: It is essential to ensure that the P660 turbocharger is compatible with your specific Subaru WRX STI model and engine configuration. Incorrect installation or usage of an incompatible turbocharger can lead to significant engine damage and expensive repairs.

The decision to purchase and install a bolt-on ball-bearing turbocharger like the P660 from PLM-Mfg for your Subaru WRX STI depends on your priorities as a performance enthusiast. If you're looking for increased power, smoother boost delivery, and reduced lag, a ball-bearing turbocharger may be an attractive option. However, you must also consider the significant cost, potential noise increase, installation complexity, and compatibility issues associated with this upgrade. Ultimately, it's crucial to weigh the pros and cons carefully and consult with experienced professionals before making a final decision.

1. Thoroughly research the market and consult with experts to determine if a ball-bearing turbocharger is the right choice for your specific application.

2. Consult with a trusted tuning shop or installation professional to discuss the potential costs, complexities, and compatibility issues.

3. Establish a realistic budget for the upgrade and consider additional expenses, such as tuning services, maintenance, and potential repair costs.

4. Ensure that you source a high-quality, reputable ball-bearing turbocharger from a trusted manufacturer, such as PLM-Mfg.

5. Proceed with the installation process only after receiving professional guidance and adhering to all necessary safety precautions.
