When it comes to aftermarket turbochargers for this particular platform, Blouch Performance Turbo is among one of the more popular choices among enthusiasts because they are built using careful manufacturing methods to produce a more powerful direct bolt-in option. On this page, you are looking at their Dominator 1.5 XT-R 10cm2 Twin Scroll JDM Turbocharger. 

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.

A stainless steel oil line is included to make this turbocharger ready for the installaion. 

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.

Blouch Twin Scroll on JDM
NickM 3 years ago
Very good stock location turbo for those lucky enough to have access to JDM models. I switched this from my stock twin scroll VF49 and made over 100+whp extra. Lag is minimal, good stock location turbo that won't over tax a non built engine. Dyno here:

Good Turbo, very responsive, great if used with e85, Poorly thought out

I purchased a blouch 1.5xtr twinscroll to use in conjunction with my spec c manifold, uppipe and down pipe which is mandatory for this turbo. Moore performance also makes a twinscroll mani, uppipe and dp to use with this turbo but too pricey for my taste. My setup is as follows: 1.5xtr stock inlet size/no coating/turbo blanket process west tmic ID 1300 w/ rails/lines 05 STi engine ej257 with drop in CP pistons the rest is stock Tuned on pump 93 What I was wanting was a very responsive turbo with minimal lag. Something that works well on a daily driver platform but could still shine at the track. This turbo with my setup put down 358/415 on a dynojet at TopSpeed motorsports. It would have easily put down over 400whp on e85. The engine was making globs of torque right over 3k and is perfectly suited for roads like the tail of the dragon! The NUMBER ONE problem that was noticed by the tuner was that the hotside of the turbo was just too restrictive to touch into the higher numbers (400) on pump. The spec c manifold/uppipe/downpipe hurts the exhaust flow greatly and was building too much back pressure to really let the turbo breathe. Is this a bad turbo? NO Is this the best stock location turbo? NO but truly depends on your goals If you're looking to reach into the 400s on pump just go rotated.. If you're wanting a very responsive stock location turbo that has the ability to make great power over 400wheel on e85 or race fuel then this is it. If you have the extra coin to spend I highly suggest picking up the Moore Performance manifold/upipe/downpipe.

    What Blanket and Shield fits this application ,

    • A: Any aftermarket heat shield should work with this turbo and for turbo blankets we typically recommend the PTP Subaru Turbo Blanket for the Blouch Dominator 1.5XT-R series.

    I just want to make sure, my car is SUBARU WRX STI GVB JDM SPEC-C SEDAN 2012 This turbo will direct fit /replacement to my car? What is the OEM turbo inlet size? Because you have 2 different inlet size for this turbo. I've got a TOMEI SILICONE TURBO INLET HOSE (Model #TOM 451002) on my car. Thank you

    • A: If your car is the JDM twinscroll then this will be a direct bolt on.
