BCP X400 WRX/STI Turbocharger 400whp

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. Assembled locally in Michigan. See tuning results below!
