BCP X500 Turbo – 2015–2021 WRX Drop-In FA20 Upgrade (400–450+ WHP)

Got a 2015–2021 WRX with bolt-ons and wondering what’s next?

This is it.

The BCP X500 FA20 is a true drop-in turbo upgrade for the FA20 platform—no funky fitment, no custom fab, no BS. Just power. It bolts right up to all factory-style inlets and J-pipes, and it’s built to make 400+ WHP on a stock motor, and 450+ WHP on a built one.

BCP packed it with a 6+6 blade billet compressor, a twin-scroll turbine housing, and their dual-feed hydrostatic bearing system with HD thrust bearing to keep it alive under serious boost. It also includes a billet internal wastegate actuator and wastegate springs right in the box.

Whether you’re still on a stock block or going all-in, the X500 FA20 gives you serious headroom with real drivability.

Install includes:

✔️ SureSeal™ multi-layer gaskets

✔️ New downpipe studs

✔️ Billet internal wastegate actuator + springs

✔️ Stainless oil feed line kit included

⚠️ Tune is required

🚫 Don’t run an oil restrictor
