The Garrett GT28R turbine housing is a direct-replacement T25 outlet housing for GT28R turbo applications. The THWA kit specifies a 5-bolt flange and 0.64 A/R to suit common GT28R builds, and the description notes Ni-Resist construction. Use this housing when upgrading or repairing a GT28R-based charger to match compressor and turbine sizing without altering the core turbo assembly.
