To Install this Turbo You May Need TDO5 Coolant Line Install Kit, Because The thread Pitch of the TDO4 and VF turbos for the Coolant is Different than the MHI TDO5 TDO6 Which is M14 x 1.5. You can buy this coolant kit on ebay Here. (turbo oil feed line water pipe install gasket kit for subaru EJ20 EJ25)

NOTE: 2011+ Year STI Requires Rotation kit to install the turbo upgrade with the 3″ inlet compressor Housing. You must use the 3″ compressor housing for the Compressor wheels 56mm and Larger.
