2008, 2009, 2010, 2011, 2012, 2013, 2014, Subaru, STi, (GR/GV), EJ25, High Flow Turbine Housing, 10.5cm2, AMR Performance
A high-flow 10.5cm turbine housing for the 2008-2014 Subaru WRX STI (GR/GV) 2.5L Turbo, replacing the restrictive factory housing to cut exhaust backpressure and free up top-end power.
The AMR Performance 10.5cm Turbine Housing is a high-flow exhaust housing upgrade developed for the 2008-2014 Subaru WRX STI (GR/GV) equipped with a factory-style turbocharger.
Replacing the restrictive factory turbine housing with AMR’s larger 10.5cm housing increases turbine-side flow capacity, reduces exhaust backpressure, and allows the turbocharger to operate more efficiently as airflow, boost pressure, and engine speed increase.
The larger 10.5cm design is especially beneficial for modified STI applications where the factory housing becomes a restriction. Improved exhaust flow through the turbine helps maintain stronger performance at higher RPM while providing additional flow capacity for upgraded and hybrid factory-style turbochargers.
Rather than replacing the entire turbocharger system, the AMR 10.5cm housing provides an effective way to increase the turbine-side capability of compatible Subaru turbo combinations while retaining a factory-style configuration.
Key benefits: upgrades the restrictive factory-style turbine housing to 10.5cm; increased turbine-side exhaust flow; reduced exhaust backpressure at higher airflow levels; improved high-RPM efficiency and power potential; greater headroom for increased boost and airflow; an excellent complement to larger compressor wheel and hybrid turbo upgrades; retains a factory-style Subaru turbocharger configuration; developed for the 2008-2014 Subaru WRX STI GR/GV 2.5L Turbo.
For GR/GV STI owners looking to push beyond the flow limitations of the factory turbine housing, the AMR Performance 10.5cm Turbine Housing provides the additional exhaust-side capacity needed to let the turbocharger breathe and continue producing power at higher airflow levels.
