Blouch Dominator 2.5XT-R Ball Bearing Turbocharger 2002-2007 WRX / 2004-2021 STI

DESCRIPTION

The Blouch Dominator 2.5XT-R Ball Bearing Turbocharger is a stock-location upgrade for WRX/STI owners who want a turbo that hits hard in the midrange, spools quickly for its size, and keeps pulling up top on a properly-supported EJ build. Blouch rates the Dom 2.5XT-R at 490 HP capability and lists key specs including a custom low-friction, low-inertia ceramic ball bearing CHRA, a high-flow 60mm turbine wheel, and a 71mm XT compressor wheel flowing 49 lb/min.

This turbo can be configured to match your goals with 8cm or 10cm turbine housing, optional Coated turbine housing, optional 3" inlet compressor housing, and a required oil feed line selection (WRX vs STI). It’s also supplied as a complete bolt-on style package with items like a braided stainless oil feed line, oil feed restrictor, oil drain tube, coolant lines, and turbo mounting gaskets, and includes an adjustable upgrade actuator that Blouch notes is pre-calibrated to 15 PSI unless otherwise specified. 

WHY

The Dominator 2.5XT-R is a great fit if you want a turbo that delivers a broad, street-friendly powerband while still offering the airflow headroom to support a well-built EJ setup. The ceramic ball bearing center section is designed to improve transient response and “snappiness,” while the 60mm turbine and XT compressor combo is aimed at building a strong, flat torque curve that doesn’t fall off early. With the ability to choose 8cm vs 10cm, plus coating and inlet options, you can dial the setup toward quicker response or more top-end breathing based on how you drive and what supporting mods you’re running.
