BCP X400 WRX/STI Turbo – Bolt-On VF Upgrade for 400+ WHP

Looking for a turbo that spools like stock but hits way harder?

The BCP X400 is your move.

This is the mildest turbo in the BCP lineup—but don’t let that fool you. It’ll support up to 400whp with supporting mods, while spooling within 100 RPM of your factory VF-series turbo. It bolts right in, uses the stock inlet, and gives you room to grow without sacrificing low-end drivability.

Whether you’re dailying it, tracking it, or just want a car that finally feels fun again—this is the turbo to start with.

It’s built with an 11-blade billet compressor, uses BCP’s dual-feed hydrostatic bearing system, and comes with everything you need to get it installed and sealed up right.

Install includes:

✔️ SureSeal™ multi-layer gaskets

✔️ Brand new downpipe studs

✔️ Standard cover compressor housing

⚠️ Strongly recommended: aftermarket oil feed line kit

💥 No tune required technically, but highly recommended for power gains
