Blouch Dominator 3.0XT-R 10cm^2 Twin Scroll JDM Turbo 2002-2007 WRX / 2004-2021 STI

Investing in a larger turbo as well as supporting mods is one of the best power upgrades you could buy. Blouch is the leader in turbo development; they consistently build the best turbos. The new XT-R line of turbos from Blouch consists of a billet compressor wheel to optimize the aerodynamics of a turbo and increase compressor flow within the same inducer geometry. 

This allows you to build more horsepower at lower boost pressure. 

It also consists of a 55 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 15 PSI and with their new 10cm2 bolt on turbine housing. 

The larger turbine housing reduces turbine inlet pressure and increase peak horsepower output. 

This twin scroll turbo requires a twin scroll header, uppipe, downpipe and cat back. None of the listed items will cross over with a non factory twin scroll car.
