Forced Performance Subaru STi/WRX Blue Turbo 58mm Black Housing External WG w/Oil Line (D/S Only)

If you're looking to significantly upgrade the performance of your Subaru STi or WRX, a larger, more efficient turbocharger is a key component. This Forced Performance Blue turbocharger is designed to replace your stock unit and unlock more power, especially in the mid-to-high RPM range. It features a 58mm compressor wheel, which is larger than stock, allowing it to move more air to fuel your engine's increased demands. The black housing gives it a distinct look under the hood.

This turbo is built with an external wastegate, which helps to better control boost pressure compared to an internal wastegate. This precise boost control is crucial for maintaining consistent power delivery and protecting your engine from over-boosting. The package includes an oil line, which is essential for proper lubrication and cooling of the turbocharger's rotating assembly. The 58mm compressor wheel is a popular choice for enthusiasts seeking a noticeable power increase without going to an extreme setup, offering a good balance between responsiveness and top-end power. It's important to note that this turbo is not CARB approved and cannot be shipped to California.

When installing a larger turbo like this, it's often recommended to consider supporting modifications such as an upgraded fuel system, exhaust, and tuning to take full advantage of its capabilities and ensure optimal engine health. Always refer to the manufacturer's installation guide for specific details and requirements.
