Blouch Dominator 1.5XT-R Ball Bearing Turbocharger Subaru WRX 2002-2007 / STI 2004-2019

Regular price $1,645.00


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!

Nice turbo

8cm nerly Spool Oem turbo great sound and good quilty thank blouch with nice black color looking good under the hood.
With Methanol 50/50 make 380 whp & 91 oct ,with big Tmic and support mode.

So good!

Turbo came with everything you need including studs, gaskets, and oil line with adapter. I had to grind a small amount off of the turbine inlet flange to get to to seat fully on the uppipe since I installed on a 2005 Legacy GT. Spool is around 3800 rpm with killer b equal length and it pulls HARD to redline. Cannot recommend the dominator series enough for ease of install and performance.

Good turbo

To start with with this turbo. The quality is great and looks very good. The sounds the turbo makes on spooling is great. The down side of the turbo is the fitment. It sits way to low on the uppipe pedestal. so had to modify the turbo feed line to the right cylinder head. Just to make sure the turbo sat flush and did not contact the the feed line. Also would be nice if there was a wastegate delete kit for it. Had to make a custom delete bracket.
