Blouch Dominator 1.5G2-R Ball Bearing Turbo For Subaru WRX / STI

BLOUCH DOMINATOR 1.5G2-R BALL BEARING TURBO

The Blouch Dominator 1.5G2-R Ball Bearing Turbo is a high-performance turbocharger designed specifically for Subaru WRX and STI applications, capable of delivering up to 520 horsepower. This turbo is a well-suited upgrade for those looking to enhance their vehicle's power output while maintaining responsiveness and reliability.

Key Features:

• Custom Low-Friction Ceramic Ball Bearing CHRA: The turbo is equipped with a custom ceramic ball bearing center housing rotating assembly (CHRA), which offers significantly lower friction and inertia compared to standard journal bearings. This results in faster spool times and improved throttle response, making it ideal for both street and track use.
• High-Flow 56.5mm Turbine Wheel: The turbine side features a custom 56.5mm turbine wheel designed for low inertia. This high-flow turbine wheel allows for efficient exhaust gas scavenging, improving overall turbo efficiency and contributing to quicker spool-up times.
• Blouch 71mm G2 Compressor Wheel: On the compressor side, the turbo is fitted with Blouch’s advanced 71mm G2 compressor wheel. This wheel supports an impressive 52 lbs./minute of airflow, which is critical in delivering the substantial power gains while maintaining efficiency across various RPM ranges.
• Exhaust Housing Options: The Dominator 1.5G2-R is available with either an 8cm or 10cm exhaust housing. The 8cm housing is generally preferred for quicker spool and responsiveness, while the 10cm housing offers greater top-end power for higher boost levels and is suitable for more aggressive setups.

Application Notes:

- This turbo is a direct fit for Subaru WRX and STI models, providing a bolt-on solution for significant power gains.
- For 2005-09 Legacy GT, 2005-09 Outback XT and 2008-14 WRX models, the installation of this turbo requires the use of a Front Mount Intercooler (FMIC) to ensure adequate cooling and performance under higher boost conditions.

The Blouch Dominator 1.5G2-R Ball Bearing Turbo is a balanced option that provides robust power output with fast spool characteristics, making it an excellent choice for enthusiasts seeking both performance and driveability.
