I haven't seen any new compressor diagrams for these on their site though. Are you sure they also sell new wheels?

Would the Blouch wheels then be the same or did they really R&D their own billet wheels?

jeez....at least garrett's downplaying the gains

they claim 10% for the pr and flow but the graph shows a 25% increase in PR and 20% on the flow....

anyways, the garrett stuff is only available for the GTX4294R, GTX4202R, and GTX4508R and there are probably only 25 subarus in the world with turbos that large.

Expect those wheel to be in their entire line in the next two years. At least that is what I was told.

Meth or race gas would help a little, but the issue is clear from all the dyno plots I've seen for the XT-R's, big hotside sacrifices spool for top end. Physics wins again.

Bet you'd be happier with a 1st gen DOM 3.

I have to disagree. I had the 1st gen DOM 3 and I sent it back to Blouch to upgrade it to the XTR, and there is no comparison between them. The XTR is a much better turbo. If the turbo spools 200rpm later, you will not even feel the difference while driving, and considering it pulls like a freight train all the way to redline, it is way worth it.

i agree with this.. the dom 3 xt-r is a monster turbo and holds nuts all the way to redline and beyond..

stepping down to a 2.5 xt-r would likely hold disappointment if it falls flat at high rpm/high speed forcing a shift way before necessary..

i would really like to shift the slope of the xtr plot left by a grand.. ive already added meth and am wondering if going back to a TMIC would help achieve this, or [a smaller hotside]??

A smaller hotside will begin to kill the topend you love so much with the XT-R. Likely also the TMIC. So far I'm sticking by with what I've seen that these turbos make power up top and you have to wait for it. In reality is that not what you'd expect from a large hotside? I can't wait to see what the 2.5 XT-R looks like, but I'm guessing it'll be a little disappointing. Its delayed isn't it? Wonder why? I think a rotated setup still wins over these turbos.

And I'm not a Blouch hater. I have every intention of getting a Blouch turbo this spring, just not an XT-R.

Hey guys, does anyone run the dom4xtr on the street in the tristate area?

Im very curious as to how it performs on 93 octane compared to my turbo (60lb/min and only 7cm).

Speaking physics, the 4.0 should dominate. But im not sure thats going to be the case.


I need to decide whether the 10cm back housing is worth the money. Right now my turbo will hit 23.5 psi, and hold it from 4800-7300.

all this stuff about low end vs. top end......

you wanna keep low end? stay on the stock turbo. just my .02

as for the latter, the choice is obvious.

def agree with this,it just holds boost so much better than the old dom 3.and like you said when driving ,you can't even tell the difference in spool.

didn't you see the first page and the first post.....

That Dom4 XT-R make 430whp on CBRD's dyno on 93oct thats 430whp airboy right there .

Thats like 50-40whp more than what you make on pump, I really think you will gain 30-40whp by switching to a larger back housing

Not everyone cares about highest numbers or driving around at 5K-7K all the time. I'm not bashing the turbo but there's obviously still a place for 18G's in the world.

im putting an 18G on in the spring, believe me i agree. im just supporting this line of turbos for those few of us who dont feel the need to go rotated to make 11-sec capable power levels. but its like no matter where ya go theres constantly someone who has a gripe about spool or price or some other.....thing.

every friend i have that i know of that is in the process of building their cars, that i have told about this lineup, is deff considering a purchase (versus a rotated kit) of one of these.


still waiting on some more 2.5XT-R results.......there is a video on youtube of one but i have to find the link....

ahh here it is...


if you read the description only the hotside has been upgraded ( i think) so its not a complete XT-R upgrade. but still good results, especially on a mustang dyno.
