Blouch Dominator 4.0 XT-R Ball Bearing Turbocharger

The Blouch Dominator 4.0XT-R features our new state-of-the-art 60 lb/min fully machined billet “XT-R” compressor wheel in our own 3″ inlet bellmouth compressor housing, Garrett GT full ball bearing system, a high efficiency Garrett GT turbine wheel

and the new Blouch 10cm² turbine housing.

So what’s the big deal? The new Blouch XT-R billet compressor wheels are simply amazing and outperform traditional compressor wheel aero by producing more horsepower and torque at lower boost pressures. Born and bred in racing development, the Garrett GT turbine and ball bearing system are the mainstay of turbocharger performance. And the new Blouch 10cm2 turbine housing reduces turbine inlet pressure and engine pumping losses to free up additional torque and horsepower. (These turbine housings work so well that customers have bolted them onto our competitor’s turbos and significantly increased torque and horsepower). The big deal is a stock location bolt-on upgrade Subaru turbocharger using state-of-the-art technology that supports 600 crank horsepower efficiently with fitment that is unparalleled in the industry.  Only at Blouch Performance Turbo! 

Choose from 8cm² and 10cm² turbo housing. Optional ceramic coating for the turbine housing is available at modest addtional cost. (Note that ceramic coating may add 1-2 weeks for delivery.) 

NOTE: The Dominator 4.0XT-R is a bolt-on upgrade that requires a 3″ inlet.  Blouch Turbo specifies that installation requires either aftermarket TGV housings or heavy modification of OEM TGV housings to clear the very large compressor housing.

Fits all 2002-2007 WRX, and 2004-2021 WRX STI.

Note that all Blouch turbochargers are custom-built to order and may not be returned.
