Turbine Housing, V-Band Flanged Entry GT4294/GT4202, GT42RS GTX42 W/4″ Discharge

This V-Band flanged turbine housing is built for Garrett GT42 and GTX42 platform turbochargers, giving serious builders the flexibility to dial in exhaust housing sizing without sacrificing flange compatibility. It’s designed for enthusiasts and shops running high-output GT42-series turbos who need a broader A/R selection than what’s typically available in comparable aftermarket housings. If you’re chasing a specific spool and top-end balance on a big-power build, this housing gives you the sizing options to get there.
