This Turbo has been averaging between 315 - 320 WHP, & 315 - 320 FT LB's of Torque when combined with 650cc Injectors, & a High Volume Fuel Pump on 2008 WRXs & properly tuned.
This is a straight forward swap no mods other than proper ECU Tuning is necessary, although Fred beans Parts does suggest upgrading your fuel sytem to help the Turbo reach its full potential. However, the oil line bracket is not needed with the VF52, there is no spot to attach it at. Also the Turbo heat shield is going to require a little trimming due to the differences in the actuators.
