Performance & Application
This turbine housing is engineered specifically for turbochargers running a 56.5mm turbine wheel within the GT30R and GTX29 series. The internally gated design integrates wastegate control directly into the housing, simplifying installation and boost management for builds that don’t require external wastegate plumbing. With two A/R ratio options available, builders can choose the housing that best matches their target spool-up behavior versus top-end flow, whether prioritizing quick response or maximizing high-RPM power. This housing is a direct fit for those upgrading or rebuilding within the GT3071R-WG, GT3076R-WG, GTX2971R, and GTX2976R turbocharger family.
