The Boost Controlled Performance X400 Turbocharger is the best mild stock turbo upgrade you can find for EJ-power Subarus. Like the X500 turbos, we’ve combined an unparalleled quick-spooling turbo matched with high volume airflow. The X400 will support 400whp while spooling within an incredible 100 rpm of the stock VF turbo. With a stock inlet size, it truly is a bolt-on unit.
