The Blouch Dominator 1.5XT-R is a little tweak to our already popular Dom 2.5XT-R.  (As I have mentioned before, we are never satisfied with status quo and we are always tweaking something).  Originally designed for our 2.0L customers in the UK, the Dom 1.5XT-R uses the Garrett GT 56.5mm turbine instead of the full 60mm turbine of the Dom 2.5XT-R.  The end result is a slightly quicker spooling turbo while trading off some high RPM horsepower capability.
Beyond the turbine wheel, the Dom 1.5XT-R consists of the same cutting edge turbo technology that you have come to expect from Blouch Performance Turbo: Blouch billet fully-machined closed die forged 49 lb/min XT-R compressor wheel with state-of-the-art aero, our own custom compressor housing machined in-house and designed for improved fitment, Garrett GT ball bearing center housing and Blouch custom 10cm2 turbine housing with adjustable upgrade actuator. 
No boost creep worries here with the smaller turbine - our turbine housing and wastegate actuator are designed to work together to ease your tuner's job and provide the flattest possible boost curve.  All of this complete with turbo mounting gaskets, oil feed restrictor, braided stainless steel turbo oil feed line, oil drain tube, coolant pipes, banjo bolts and copper washers.  Only at BPT!

HIGHLY underated turbo

, Jul 24, 2012
I made 327whp & 310ft/lbs. with this lil monster. Fantastic mid-range power; I am seeing full boost @ 3800rpms @21.8psi. I got the 3" inlet and 10cm^2 variety, coupled with a TMIC, 850cc injectors and big maf intake this turbo will not disappoint! It has the same sized turbine as the 20G XT-R with the compressor size of a 2.5XT-R; which makes for a great turbo for Subaru hybrid motors. Installation would require, in my opinion, TGV deletes. I also found that because of the hard inlet pipe I used that moving the up-pipe brackets out of the way and removing the up-pipe itself for enough clearance when sliding the oil return tube into the engine hose and mounting the inlet made life A LOT easier!! This was also the last Blouch turbo Chris Schoen-Kiewert at EFI Logics ever tuned...RIP buddy.
