Tomei ARMS BX8265 Turbo Subaru Models (inc. 2002-2007 WRX / 2004-2021 STI)

This turbo is a direct bolt on for ALL EJ ENGINES! This unit comes with all gaskets, lines and fittings needed for install. IF YOU HAVE A 2008-2014 WRX OR 2005-2009 LGT, you'll need to either have a FMIC or Verticooler as this turbocharger uses the STi style compressor outlet.

This turbocharger features a CNC billet compressor wheel for durability over the conventional cast compressor wheel, and it also features Tomei's Multi-Rate Billet Actuator to allow the user to perform fine-tuning of the boost so you can hit your preferred targets every time,
