Blouch Dominator 1.5XT-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.
All of this combined with Garrett GT turbine and full ball bearing technology to produce a complete bolt-on package that includes stainless steel turbo oil feed line and steel oil drain tube and coolant lines. Adjustable upgrade actuator is standard issue on the 1.5XT-R and is pre-calibrated to operate at 15 PSI unless otherwise specified. The 1.5XT-R has a 56mm turbine to promote better spool up and a better overall turbo.
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.
