It's the motor for a variable exhaust flap.

Really!!! Thanks

So I'm new here and I bought this beautiful vehicle in 2015 and I have done stuff to it. And when I went to get it tune, the guy said he can't tune it until it's working properly. I found out I was leaking boost. It was suppose to be around 14psi but I was only getting 4psi.
We did boost checks and found several each time and the psi increase from 4 to now 11. However air is escaping from the secondary turbo, we can hear it but not see it nor feel it. I even try smoke and we didn't see any smoke escape. Weird yeah I know. I was told the actuator could be the problem and I check that and it was good although the setting were wrong and I adjusted it the the right setting distance and the was the last thing I did. I'm now out of option. I did notice a actuator looking part under the top mount inter cooler that has traces of oil coming from it. Was told it's the Intake air solenoid but I can find anything online like it. 😢😢
I'm a DIY guy and I live in a country where there are only about 6 of my vehicle that I have seen so far.
I really want to get it to its optimal performance and install some gauges and have it tune and I'll be the happiest an on earth.
I will post some pictures of what I have done to the wagon so far.

Installed a rear stabilizing bar
A 4 point front lower stabilizing bar (this one is crazy, all corners feel like a straight road)
Removed the cat and the resonator. But it stil sounds quiet, I believe due the the other cat by the primary turbo down pipe.
And the last picture is 2002 Subaru Legacy GT-B E-Tune aka Toothless
The rest pictures are not shown...
I also install hood damper. Really love that part the most. Don't have to look for a arm to keep the bonnet open
6 discs changer Pioneer DVD stereo and I was lucky to get it to work with the Japanese navigation screen, so I can still see my air-condition functions
I'm sitting on 215/45/18 Goodyear Eagle F1 and I had to get all 4 fenders flared to avoid rubbing.

Welcome.

[duncanm]

the valve under the IC you're talking about is the intake control valve (ICV. Not to be confused with the IACV)

http://www.subyclub....-to-twin-turbo/

 

They usually look oily, because any blowby that accumulates in the TMIC tends to dribble down the secondary turbo outlet pipe and sit in the valve, where it then leakes out the shaft of the butterfly valve.

[Arfreedom]

What!!!! Omg.
So I should really install air oil separator? I notice the pipping have 3 points of oil (2 breathers from the side and the one in the back not sure what it calls)
1) can I just install a oil catch can for the 2 at the sides that will help or the majority come from the one at the back?
2) so just clean the area and ICV exterior and it should be ok.
That won't cause a boost leak?

Well -- its no more blowby than usual in an EJ20T, its just that the secondary rarely gets a workout, so what little oil there is accumulates there.

 

There's instructions on appropriate catchcan installation elsewhere on subyclub

 

For now - as you say, pull the secondary outlet tract and TMIC off and give the whole lot a clean inside and out.

 

Never heard of the valve leaking enough to cause boost issues.

[Arfreedom]

Thanks Duncanm ,
I read somewhere that there is some kind of spray to spray inside the intake that cleans out the intake as well as the turbos...
Is there such a thing?

Now based on what I got feedback from. Thank you guys. I will change out the vacuum lines in my bbod and see if I get boost. Yes I know about the pill in line 2.
What I'll do is show a video on how it performs later

A 4 point front lower stabilizing bar (this one is crazy, all corners feel like a straight road)

- Now I want one. How much was it and where from?

 

I installed catch cans. One for the head breathers and another for crank case. I found the oil cleared up when I fixed my boost leaks though. It seems these turbos blow oil when they're over worked. Now the cans mostly catch condensation during cold morning starts during winter.

[duncanm]

Luke -- used ones are all over yahoo JP and similar: try here for starters
 
Pretty cheap (but you'll pay in shipping).
 
Have been thinking about one as the basis for an alloy sump guard, myself - but worried about how low they hang.
 
Anyone have anything definitive about how effective / noticeable they are?

Hi Luke, I'm a eBay junkie here is a link to the bar
http://www.ebay.com/...9xXOqUV&vxp=mtr

Yes indeed there are very reasonable but the shipping to much country costume a great deal but it was well worth. It.
Installation was plug and play. And fit right inside under the carriage and look it was built for it with plenty of clearance.
Before I had it installed when I go around corner the wagon would lean very bad (I know stiffer shocks and springs will solve that) but I went with this bar first. And it was the best investments. I can now go around the corners now at extreme speed and the wagon just sit down with little body roll.

Oh can you send me pictures of how your catch can looks and where you installed them in the engine bay?

I did a smoke test and would you believe the smoke was going in but I couldn't find the smoke going out. Know know if I was doing it right.
I use a fog machine and built a hose to connect to the intake. But nothing.
I later found out that my secondary actuator was open and I adjusted it (help from YouTube) but still no difference.

I have seen different diy smoke test on YouTube and they see smoke coming out in places so to see no smoke coming out was strange.
I will try again now that the actuator is closed and see what happens and do a video for you guys to see and correct me if I'm doing something wrong.
Also was also going to clean the solenoid so in the BBOD but don't know where to start and change out the hoses too. Help anyone there

Did you block off your air filter? If so, the smoke might have come out the exhaust depending on what position your engine is at. Also, does the smoke from a fog machine last long enough to see it escape somewhere?

 

When I do my smoke testing I use a milo tin or a paint can with a oily old rag in it. Just hook up a couple of hoses to it; one goes to a compressor and the other into the intake somewhere on the car. Ideally you want to be able get the compressor to pump out a slow steady flow or it will just blow the lid off the can. Once you get the rag alight, let it burn for a bit, blow it out and let it smoulder for a minute inside the can before turning the compressor on; otherwise the compressor will fan the flames and things get a bit hot to handle! If that happens turn the compressor off and starve the can of air. The choice of rag helps, something the burns slow but smokes a lot.

 

I generally block the air filter just enough to push the smoke out any air leaks, but not so much that it won't blow out when the pressure builds up.

 

Thanks for the link to Ebay. I'm seriously tempted. My car is very stiff at the rear, but I think the front could be better.

[LukeFranky]

Oh, and it shouldn't matter if the secondary actuator (ECV) is open or closed.

 

Finally, check out the 'Your Guide to Twin Turbo' page for information about BBoD: http://www.subyclub....-to-twin-turbo/

Just pick up my wire harness fore coil packs from the post office yesterday. But before I install them want to change out the spark plugs for the first time. What is recommended for my ej208, 2.0l twin turbo?
Also I see that they have new ir fusion spark plugs.... Does anyone knows which type will fit my engine. I saw one on Amazon that fits the ej25 but not Ej20. Or any experiences with that same plugs??

I use Iridium but that's not what these other guys on here recommend.
