This 0.82 A/R T3 Divided turbine housing is engineered for enthusiasts running Garrett’s GT30R and GTX30R family of turbochargers who demand the throttle response and exhaust scavenging benefits of a true twin-scroll setup. Built as a genuine Garrett casting, it’s the housing of choice for serious builders who refuse to compromise on spool characteristics or outlet flow. Whether you’re running a GT3071R, GT3076R, or one of the GTX30/GTX29 variants, this housing is purpose-built to extract maximum performance from a 60mm turbine wheel.

Specifications

• Turbine Wheel Size: 60mm
• A/R Ratio: 0.82
• Flange Type: T3 Divided (Twin-Scroll)
• Outlet: 3″ V-Band (welded)
• Construction: Garrett casting

Performance & Application

This twin-scroll turbine housing is designed to keep exhaust pulses separated from each cylinder bank, improving scavenging efficiency and sharpening turbo response compared to an open, undivided housing. It’s built specifically around a 60mm turbine wheel, making it the correct match for the GT30R, GTX30R, and GEN2 GTX30 series of turbochargers. For builders running GT30R-WG or GTX29 series units, this housing serves as a proven alternate fitment option. The welded V-Band outlet simplifies exhaust-side plumbing while maintaining a robust, leak-free connection for high-boost applications.

Compatibility & Fitment

• GT3071R
• GT3076R
• GTX30R series
• GTX29R
• GEN2 GTX30 series
• GT30R-WG (alternate fitment)
• GTX29 series (alternate fitment)
