Not sure on the XT... If it's anything like the Dominators... Think Kirt brought up something regarding the differences being the spool time ?

The oil you are talking about is more than likely the normal amount. I had that issue often. You can either always be taking off your intercooler and cleaning it, or like Paul mentioned get the GS AOS, it will/should solve your issue. I should find out in about another 900 or so miles.

The XT series just means they have the billet wheel upgrade and the R at the end means the Dominator turbo is a ball bearing. The ball bearing and billet wheels are suppost to help with spool up over a thrust bearing turbo. Granted the XT is a better spooling thrust bearing turbo. Its up to personal opinion and tuner preference if you want ball bearing or not. But, its suppost to help out.

your oil is normal i bet. all these cars get oil in the inlet, turbo, intercooler and TB from the crank case and valve cover vent return lines going into the inlet. the GS AOS is an option but not a great one because of the FMIC piping. theres not a lot of room to install one and it will hit the piping. i spent about $30 and made my own. it collects crank case and valve cover blow by and it vents to atmos. when it was venting back to the inlet i still had blow by getting into the inlet and every where else. its a very very very small amount but because im blow through it would dirty my MAF sensor. for the street the GS AOS is good but track guys still get oil coming out and soaking the inlet. hard right hand turns i bet is the problem.

FYI its flat black now.

I will definitely take a look at it when it comes time.

I hope it is. I added the GS AOS to my list yesterday. I will take some photos of my findings. That will help you see what I am seeing.

I appreciate the info. I will contact Blouch and the Cobb tuner in Plano. Gather some ideas from both side and make my decision from there.

Thats a nice little contraption you have there. What FMIC are you running?


As for my boost leak, I think for one my Wastegate may be hosed. I was looking at the data on the AP and just by barely (and when I say barely I mean super barely) pushing on the gas pedal my WG Duty Cycle was at 67%. Then, I did it again and it started going all over the place. I should be hitting around 18psi on my boost. Max I was about to achieve was 15.1psi. I was going thru the gears and max was 11.7psi, but when I started out in 3rd at 2500RPM, that is when I achieved 15.1psi. Has anyone done a smoke test to check for leaks?

I think you'll be good with either the 440 or 480 xt series, or if you go front mount the 20g-xt.

They're all in the 44-48lb/min range. If you really want to be safe on the stock internals I would get the 440, and it's still a decent increase over the TD04 you have now. Either way with a turbo much bigger than the VF52/48 you're risking the pistons.

Why if FMIC go with the 20G-XT?

Got off the phone with the Subaru Dealership. Smoke testing is the answer!

Because the 20g-xt is the old turbo layout, it doesn't have the flange like the 08+ stock turbo's have. The 440/480-xt's have the flange. I wasn't saying if you go FMIC get the 20g, just that if you want the 20g you need FMIC.

Still not really understanding what your saying

If I decide to go with 440/480 then I will want to stay TMIC, and if I want to go FMIC, then I need to stick with the 20G-XT?

Maybe I was reading it wrong...

06f250sd is an unknown
You can use any turbo combination with the front mount. With a tmic (perrin, AVO, stock) you are stuck with the LGT style turbo. The only aftermarket tmic that can use any style turbo is the Process West.

Update 3/1/2011

Ok,

I am stuck between the 20G-XT and the 480XT. I am placing one on order today. Turbo XS FMIC will be ordered today as well. Plus the supporting mods.

What kind of help are you looking for? Notice the flange difference in between the two.
