The BCP X500+ Turbocharger is the ultimate stock location solution for EJ-power Subarus. Like the X500, we’ve combined an unparalled quick-spooling turbo matched with high volume airflow. The X500+ will support up to 550whp with proper supporting mods. 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.
Our line kit offers stainless braided high pressure AN lines and AN fittings to ensure proper flow volume and leak-free operation.
We have turbos in the field with over 60,000 miles of hard use with unmatched reliability! Please note, this turbo is only available in the STI-Style compressor housing. You will need to clearance your air pump hard line on 08-14 WRX to address a minor clearance issue on the compressor cover.
