Forced Performance 2015+ Subaru WRX FA20 Blue Turbo LOPE BB External WG w/Welded Flapper

Forced Performance is well-known for building robust turbochargers that can handle serious power. This Blue LOPE BB turbocharger is designed for the 2015 and newer Subaru WRX with the FA20 engine. It features a ball-bearing center cartridge for improved spool and durability, and an external wastegate setup with a welded flapper for better boost control. This turbocharger is a significant upgrade for those looking to increase horsepower and torque beyond stock levels.

The LOPE Blue turbo uses a larger compressor wheel and housing compared to the stock unit, allowing it to move more air. The ball-bearing design means less friction inside the turbo, which helps it spin up faster and respond more quickly to throttle inputs. This translates to a more immediate feeling of power when you step on the gas. The external wastegate setup is a key feature for fine-tuning boost pressure. Unlike internal wastegates, an external unit can be plumbed to vent exhaust gases more efficiently, leading to more stable and precise boost control, especially at higher power levels. The welded flapper on the wastegate ensures it stays sealed when closed, preventing boost leaks and maintaining consistent pressure.

This turbocharger is intended for modified vehicles and requires supporting modifications for optimal performance and reliability. It is not CARB approved and cannot be shipped to California. Please ensure you have the necessary supporting modifications, such as an upgraded fuel system and engine tuning, before installation.
