The X400 Turbocharger is the best mild stock turbo upgrade you can find for EJ-power Subarus.

Like the X500 turbos, we've combined an unparalled 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. Turbo includes everything you need to install including our SureSeal © multi-layer gaskets to ensure leak-free operation and brand new downpipe studs. We Strongly suggest running our line kit or another aftermarket feed line kit to ensure adequate oiling to the turbocharger.

Tune Required? Yes an ECU Calibration is required to use this turbocharger. Professional installation is highly recommended.
