Features & Product Details

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 Blouch Dominator 1.5XT-R 10cm2 Ceramic Coated 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 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.

Note that this particular turbocharger will come with a ceramic coated exhaust housing for extra protection against heat and corrosion, and it will also come supplied with both coolant and oil drain pipes already installed. Additionally, an oil feed line, new hardware, as well as a new downpipe and up pipe gasket will be included to make this turbocharger ready for the installation.

Noticeable lag but great turbo overall 11 months ago
5out of 5stars

I was torn between this turbo or Tomei M7760, I didn't want to sacrifice drivability over power. These turbo has the same turbine size (56.5mm) but the 1.5XT-R uses bigger compressor 71mm over 68mm. From what I read the 10cm is better suited for the 2.5L, while 2.0L engine would be better off using the 8cm. My car is a 2011 Subaru WRX STi on a stock engine with various supporting modification. It has noticeable lag, the ball bearing helps reducing the lag to around 300 rpm for the same HP before 4000 RPM and pull away all the way afterwards and raise the top HP around 50 HP on a Dyno Dynamics.

Great turbo. Spools decently and pulls hard Installed on a JDM EJ207 Should have bought the Blouch TD05H-18GXT Billet Turbo 8cm^2 for even better turbo response

2010 WRX stock block and tranny, e85 @ 24psi 3 years ago
5out of 5stars

Running this turbo with a PW TMIC, and FIC 1100 injectors and hitting 86% on duty cycle. 24 Psi is where the MAF reached its limit and a 4 bar map sensor is needed to go beyond that and a speed density tune would be utilized from there. Ok, so I got the 10cm2 housing and the housing ceramic coated...I'm hitting full boost at 3800 RPM with Tomei UEL thermal wrapped headers, catless Invidia DP (also wrapped) and a turbo blanket. Not going to lie, it spools a bit faster of course on a stock VF52, but this turbo still spools quick with and holds the boost to least to 23.5psi by 7k which is nice. As I said, stock block and tranny, running South Bend 550lb ft 4 puck clutch (sprung) You will NEVER have enough power and never be satisfied, but if you could be, this is a great turbo. I'm putting down somewhere just north of 400/400 on a Mustang Dyno with this setup and closer to 480hp Dynojet. I knew that stock block/tranny, this turbo was about as much as I could get away with. Beyond these power levels, you're looking at a build due to the head studs failing typically around 25psi or so. E85 solves the ringland problem best I can tell at these boost levels though, and jury still out on the tranny, but I don't use FFS or launch control...but even then, I wouldn't feel comfortable going beyond these power levels. A good stopping point really to keep things within budget. Happy Boosting everyone!

Conservatively tuned on e85 427hp437tq 4 years ago
5out of 5stars

Great turbo. Spools decently. I haven't datalogged to see when it's hitting full boost, but floor it at 4k and this turbo pulls HARD. I have this on my 2010 WRX. When I went to get it tuned, I was told about the limitations of my setup. Ring Lands, Head Studs, and OEM tranny are all holding me back from this turbo's true potential which I was told by the shop could throw down 500lb ft tq on e85. Running it with a target boost of 23psi with gobs of ignition timing. Frankly, if you're on 91 octane, this isn't the turbo for you. On 93, it get's 10% more hp/tq than 91. But e85 is where this turbo is at. And even then, I feel I'm not utilizing it's full potential. I'm almost thinking I should have gotten the 18G ball bearing Blouch for even quicker spool and would have less peak power, but maybe I might have been happier? Don't get me wrong, I love the rush, but I really think I need a few more PSI to really wake up this turbo and have it hitting hard. But, the cost to swap out pistons, head studs, and a tranny swap is just not worth getting another 50lb ft. Moral of the story...aim a little smaller with the 2.5L WRX. If you have an STi, go for it. Your trans is already up to the task, and a few extra thousand tidying up the ring land and head stud issue can get this turbo performing where it should be. BUt, at that point, maybe the next step up to the 2.5XTR or 3.0 might be in order? Ok, thx for listening.

  • Q: Fitment   Dan Harper3 months ago

    What would be needed to fit this on an 2011 Wrx with a process west verticooler. ?
  • Q: DOM 1.5 vs DOM 3  Suaku163 years ago

    Which will be a better choice for a WRX 07 auto 5 speed transmission. What will be the performance difference?
    • 0 of 0 people found the following answer helpful

      A:  Im not sure what the wrx 5 speed auto can hold power wise. I think as far as performance goes, the 1.5 would be a good choice. I would look into a 16g or 18g if you dont plan on upgrading your transmission.

  • Q: vs gtx3071  korinthia4 years ago

    Im not beating a dead horse I swear, I see that you have said this will perform similarly to a gtx3071r, Im assuming though you guys are referrring to the ATP stock location variant, what I would like to know is how this turbo compares to a rotated gtx3071r .63 a/r
    • 0 of 0 people found the following answer helpful

      A:  This turbo will still be comparable to a rotated 3071R, but rotated will provide slightly quicker spool and about the same top end.

  • Q: Injectors  Shane Hollis4 years ago

    What size injectors do you recommend to get the most out of this turbo?
    • 0 of 0 people found the following answer helpful

      A:  That depends on the fuel type, but if you are using regular pump gas 1000cc would be plenty.

      A:  On e85 however, you will need at least a 300lph fuel pump and FIC 1100's (actual flow rate closer to 1200) or DW1300's ID1000's will limit your tuning possibilities.

  • Q: Turbo comparison  Bencwj4 years ago

    So which will give a better power output? And which spools faster compared to the gtx-3071R. What's the benefits for ceramic coated
    • 0 of 0 people found the following answer helpful

      A:  This turbo will be very similar in terms of performance when compared to the GTX3071R. The 1.5 Dom will have a slight edge in power and response though. Ceramic coating helps reduce heat in the engine bay, and keeps heat in the turbo, making the turbo more efficient.
