The Garrett GT28R turbine housing (THWA) is a replacement turbine housing configured for a T25 5-bolt outlet with an 0.86 A/R ratio, listed here as Hi Sil. It houses the turbine and helps direct exhaust flow to the wheel; the 5-bolt T25 flange suits compatible turbine outlets. Use this housing when rebuilding or upgrading a GT28R-based turbo, and confirm fitment against your turbo model and flange requirements.
