Blouch Dominator 4.0XT-R Full Ball Bearing Turbocharger
The WRX/STi Dominator 4.0XT-R features Blouch's new state-of-the-art 60 lb/min fully machined billet compressor wheel, a high efficiency Garrett GT turbine wheel, Garrett GT full ball bearing system, adjustable upgrade wastegate actuator calibrated at 19 PSI and their new 10cm2 bolt on turbine housing.
All test results indicate that, in addition to being lighter and stronger, the new Blouch "XT" compressor aerodynamics will outperform existing compressor wheel aero by producing more horsepower at lower boost pressures.
They combined this new billet aero with our new 10cm2 turbine housing to further reduce turbine inlet pressure and increase peak horsepower output.
These turbos are built to order, so please allow a few extra days for shipping.
NOTE: The Dominator 4.0XT-R is a bolt-on upgrade which requires a 3" inlet and TGV deletes. It requires no modification to oil feed, oil drain, coolant or exhaust connections for installation.
