Blouch Performance Turbo Dominator 5.0XT-R Ball Bearing Turbocharger w/ 3" Inlet 2002-2007 WRX / 2004-2021 STI | 650HP Capability | High-Flow Ball Bearing Turbocharger
Overview
The Blouch Performance Turbo Dominator 5.0XT-R is a high-capacity ball bearing turbocharger designed specifically for Subaru WRX and WRX STI models from 2002 to 2007 and 2004 to 2021 respectively. Engineered to support up to 650 horsepower, this turbo is ideal for enthusiasts seeking maximum power output with reliable spool characteristics. It is a bolt-on upgrade that significantly elevates the forced induction capabilities of your Subaru, making it suitable for serious street builds and track applications alike.
Blouch’s design philosophy centers on precision engineering and performance optimization. The Dominator 5.0XT-R features a billet 65 lb/min compressor wheel and a custom 3-inch inlet bellmouth compressor housing, crafted to improve airflow and fitment within the Subaru engine bay. The use of a ceramic ball bearing CHRA reduces friction and inertia, enhancing spool response and durability. Unique to Blouch, the 10cm² turbine housing and custom coolant and oil feed lines demonstrate a comprehensive approach to thermal management and reliability under high boost conditions.
For Subaru owners, this turbocharger offers a transformative upgrade that balances extreme power potential with practical considerations like fitment and cooling. The 3-inch inlet requirement and recommendation for an external wastegate reflect the turbo’s high-performance intent, ensuring that the WRX/STI platform can fully exploit the increased airflow and boost pressure. This makes the Dominator 5.0XT-R a top-tier choice for those pushing their Subaru’s engine management and supporting modifications to the limit.
