BCP X400 WRX/STI Turbocharger
Quick response for an EJ Subaru upgrade
The BCP X400 is a mild upgrade for EJ-powered Subaru builds, supporting 400whp with the right supporting modifications. BCP reports spool within 100 rpm of the factory VF turbo. It retains the stock-size inlet and is currently offered with the standard compressor cover.
Specifications and included hardware
Manufacturer part number: BCP-400-007
11-blade billet compressor wheel; 44 lb/min flow rating
Dual-feed hydrostatic bearings
Stock-size inlet
7cm turbine housing with Subaru inlet and outlet flanges
SureSeal multi-layer gaskets and new downpipe studs included
Installation and options
A tune is required. BCP strongly recommends its oil-feed kit or a suitable aftermarket feed-line kit to provide adequate oil flow. The optional oil-feed kit and DEI Titanium Turbo Blanket are sold separately through the selectors above.
Confirm vehicle fitment with Johnson Tuning. The oil-kit label applies to the line kit, not universal turbo fitment. BCP recommends professional installation and provides a one-year, unlimited-mileage warranty on shelf turbos.
