BCP X500R WRX/STI Turbo – Stock Inlet, 600+ WHP

The BCP X500R isn’t just another stock-location turbo.

It set the record for the most power ever made through a stock inlet—and it’s still a true bolt-on.

Built for 600+ WHP with unreal spool characteristics, the X500R delivers big power without sacrificing response. You can throw it on a simple setup today, or max it out with a full E85 build tomorrow. Either way, it rips.

This thing uses a 9-blade billet compressor wheel and a dual-feed hydrostatic bearing system with a heavy-duty thrust bearing to stay alive under serious load.

It comes with BCP’s SureSeal™ gaskets, fresh studs, and installs like a proper stock-location unit.

Install includes:

✔️ SureSeal™ multi-layer gaskets

✔️ Brand new downpipe studs

✔️ STI-style compressor housing

⚠️ A tune is required

🚫 Don’t run an oil restrictor
