Default Blouch Dom 5.0XT-R vs GTX3076R

Any one knows how these two turbo's compare to one another?

It seems both carries billet wheels.

Which turbo is more response and have better street manner and topend for weekend drags?

a gt30 is going to have great street manners for a 2.5L

the dom 5.0xtr is way too big for anything but a built motor.

you cannot really compare the two of them, a gt30 is good for around 450whp while the dom 5 is more of a 550-600whp setup. the dom will be laggier and be better for the strip, while i would always suggest a gt30 style turbo for the daily driver...unless you don't mind lag

Out of the two, the 3076 for sure. Im just not a fan of big turbos in small frames. No matter how big of wheels you stuff in those small housings, it seems that they just stop making good power. Those small housings can only dish out a certain amount of air, no matter what the size of the wheel is.

True, but I think rotated setups should be saved for the guys trying to break records (usually car's with ported heads/cams as well). Based off of what I've seen in the last year or so on PPB, rotated setups make more power, but I couldn't personally justify the cost difference seeing that I would only make 30-40whp more than a stock location 30r vs. rotated 30r. Obviously the bigger you go, the more pronounced the benifit is, but you get the picture. OP, try and find someone in your area with a 30r sized turbo to give you a ride, I think you'd be satisfied .

Ok. Getting back on track, looking to keep it stock. Not looking to break the bank or more power.

The GTX3076R is rated to 640CHP


The Dom 5.0XT-R is 650CHP and is a 65lbs/min. Not much is know of the Dom 5.0XT-R compressor wheel except what is posted here http://www.bptstore.com/Subaru-WRXST...ger-_p_29.html. It maybe a 82mm compressor wheel.

I am looking for real world results and I see the Dom 5.0XT-R on MPS car, but never seen any reference of the two or even a comparison of the two.

Or does it perform like the GT3582R?

That's not true the ATP 3076 turbos make the same power in stock location as in rotated location. Search the thread about ATP turbo reviews it's amazing and has so much proven information by efi

I believe it compares a couple Blouch turbos to the ATP as well

The dom5 i think is a 35r, cuz its rated pretty close.

The gtx3076 is a 30r with a lighter wheel. So the deal here is that it out flows its previous 550cfm to 640cfm.

Now ask yourself, is it a true 640cfm? No. Does it spool sooner and gets you close to 35r power? Yes.

Big turbos like dom5s should be saved for ppl with headroom to spool it. So go gtx3076.

If you're dead set on the two, 3076 should have better response and street manner (granted I've never run either). Dom 5 might have more topend for weekend drags, except it's stock location.

I'd recommend GTX3076 in rotated configuration. If you're going for that much power, just do it right. I loved my rotated 30r on the street and event he 35r had barely more lag. You should be somewhere between the two, maybe closer to the old school 35r w/the GTX3076. Cams/heads, etc. won't be completely necessary for it either, yeah it'll help, but not necessary.

I DD my Dom5xtr stock heads less valve springs, built motor, tmic here's a road dyno for you to use for comparing if you want.
blue line is my S# map @ 22psi
red line is my S map @ 17 psi
both on pump 93 so very conservative timing as well
I can't comment on higher boost levels as I have not done a kill it/ race gas map at 30psi yet.


I don't mind the lag because the block is built for 8.5k rpms without trouble, just waiting to do a complete head package so I can actually make power up there and arent just revving away.

just to give my feedback...

i use DOM5.0XTR, amazing turbo very happy, i have built engine, fmic, E100,

car at 25 psi produces virtual Dyno 550whp.

honestly i came from a 68hta the turbo is laggier , but not to much,
Dom give me the kick of power at around 4600 rpm, but before this i already have LOTS of torque near of 3000 and up...

very very happy with it!

wish someone could compare a gt30r .82 hotside/.60 comp to the new gtx3576, which parts does this turbo use? Can either of my turbo housings work with stepping up to this turbo? I know the compressor housing is a little different for the gtx center cartridge, but was hoping it was something I could have my current one machined to fit

which parts are used with the gtx3576

They might make the same "peak" HP but area under the curve will be different along with egt, egbp, knock count, ect

I would also love to see some results from a GTX3576 on an Ej257

The GTX3576 uses the 11 blade billet compressor wheel from the GTX3076 with a modified GT3076 compressor cover. On the exhaust side the GTX3576 uses a GT3582 exhaust wheel and and housings. I am not sure if the CHRA is from a GT30 or GT35.

You can upgrade the compressor wheel/housing in your GT3076 to make a GTX3076, but you still need the exhaust wheel(and possibly CHRA) from GT3582 to make a GTX3576

The Blouch turbos have the Garrett tags still on the CHRA, so if anyone has a Dom5 handy it would be very easy to check which CHRA it is using.
