Forced Performance Subaru STi/WRX Blue Turbo 58mm Black Turbine Hsg External WGw/Oil Line (D/S Only)

This Forced Performance turbocharger features a 58mm compressor wheel and a black turbine housing designed for external wastegate setups on Subaru STi and WRX models. The housing is cast from durable iron, chosen for its ability to withstand the high temperatures and pressures associated with turbocharging. This specific unit is configured for the driver's side (D/S) application, ensuring proper fitment and exhaust manifold alignment for these performance Subarus.

The 58mm compressor wheel is a key component, offering an improved balance between airflow capacity and spool response compared to smaller turbos. This size is often selected for builds aiming for a significant power increase while maintaining reasonable street drivability. The external wastegate port is integrated into the turbine housing, allowing for precise boost control when paired with an appropriate external wastegate actuator. This setup is generally preferred for its ability to handle higher boost pressures more effectively and reduce turbo lag compared to internal wastegate designs.

Included with this turbocharger is a dedicated oil supply line, crucial for proper lubrication and cooling of the turbocharger's rotating assembly. Ensuring this line is correctly installed and provides adequate oil flow is vital for the longevity of the turbo. Please note that this turbocharger is not CARB approved and cannot be shipped to California due to emissions regulations. For optimal performance and reliability, consult the manufacturer's installation guide for specific requirements regarding oil and coolant lines, as well as exhaust and intake plumbing.
