The Garrett GT30R turbine housing kit features an O/V inlet with a V‑band outlet in a 0.61 A/R Ni‑Resist casting, providing the GT30R housing flow profile for rebuilds or custom turbo setups that require that A/R. It functions as a replacement turbine housing where the 0.61 A/R and V‑band connection are specified, and uses Ni‑Resist casting material common to such replacement housings.
