The Forced Performance blue UHF turbocharger for Subaru STi and WRX applications is a 58mm CH7CM UHF unit with a ported turbine housing, external wastegate, and oil feed line. The ported turbine housing suggests altered flow characteristics and the external WG keeps boost control separate from the housing. Select this ported-external UHF version when that layout and oil-fed lubrication align with your Subaru installation.
