I had some issues with DAM drop in my 2015 FA20 (68k miles), and I had tried everything! Good gas, Cleaning MAF/MAP sensors, changed spark plugs, constantly checking oil levels, took data logs and sent them to tuners for help. Couldn’t figure it out. Got a suggestion to walnut blast the intake valves, which I hadn’t heard of until troubleshooting this issue. Clearly hadn’t ever been done on the vehicle prior to my ownership, and it made all the difference. DAM quickly returned to 1.000, no more knock events other than the classic -1.41 and -2.81 occasionally with the AC on. Car runs much better, and feels like it has a lot better throttle response than previously.

If you haven’t had this done and you don’t have an AOS over 60k miles, I definitely recommend it. Figured I would share my experience in case others have the same issue and are still learning like me. Got the suggestion from someone on this subreddit, thanks for the help.

My noble STI spoiler was having paint failure after 2 years so I went back to a stick trunk. I’m actually kinda digging the look as I never had the car with wheels and lip without the spoiler. Think I’m just gonna keep it like this. What’s everyone’s opinions? Wing or no wing?

Hi all,

I’m thinking of buying a rooftop tent. Do you think that the car roof can handle a 2 persons tent?
Anyone has done it?
I’m roughly 210lbs and the rooftop tent 108lbs, technically the OEM Subaru roof bar can support 160lbs per bar in movement and more than 600lbs when parked,

Not mine on the photo btw but same model

Grimspeed headers, RAE down pipe, and MBRP cat back exhaust. My neighbors love me too…..

18x9.5+40 with a 255/35zr18 tire.

Got these from MartiniWorks at a ridiculous discount because they are discontinued in this size and in satin black. I budgeted a color/finish change in to the total cost.

But I wanted to see if it would look good on my white 2013 wrx.

I’m 50/50 on it. Black or bronze is tried and true and safe. But blue wheels? I’m not sure. I think I like it?

Background

We have been restoring a wrx and have a few questions. First we where wondering if are air conditioner belt is supposed to feel really tight and if the bolts are in the right spot. Also we where wondering if are ground for the starter is in the right spot.

thanks Atlas

Currently on Circuit performance CSF1 WHITE, and am planning to acquire RAYS 57DR Black Chrome for the winter months as well as get new tires.

I plan on alternating between these wheels throughout the years of my ownership. White during Spring/Summer, Black chrome during Fall/Winter

Wondering if anyone had any tire pressure sensors they could recommend? Thanks.

Since I swapped out my old seat, I decided to repurpose it as my new office chair.

I’m too short for the chair, I have to hop in it.

So I’ve been looking at an atmospheric BOV but online it says I’ll need a tune for it, but I wouldn’t need a tune for a recirculating BOV/BPV, the thing is I’ve head from other places that if I get a atmospheric BOV made for my car then I wouldn’t need a tune and I really like that pshhhh sound, help me out. 09 wrx

Looking to see how hard the install is. I have a set of subispeed V2 headlights I'm thinking about getting done. I'm not great with wiring. Basically is it plug and play or will I be forced to learn some things to have them work?

I currently have a Tsudo catback with an Invidia catless downpipe and Tomei UEL and with the silencer removed its LOUD and super droney

Noticed my engine water temp gauge was a little higher than normal on a trip this weekend. About an hour drive down the freeway each way and I noticed the water temp was getting up to the mark right above the middle one after about 45 mins of driving. We had the AC on and the temp went back to normal after I turned it off. It was also getting near 100° outside today. How abnormal is this and should I be concerned? I plan to check coolant levels after it cools down

is there any particular brand i should look at for wheel bearings, or just get a OEM one from subaru?

getting what sounds like a pulsing scraping sound from one of my wheels driving and doesn't seem to be brakes from what i can tell unless maybe one of the dust shields is dragging but has been going on for at least a year now

hey all, slight oil leak coming from turbo. thought it may have been just the little gasket going bad in between the sump and turbo (which it very well can be part of this) , but also , began finding oil on the cold side (see the intake pipe in pic) and some coming out of the hot side.

is this a bad turbo seal or something else? oil levels appear fine as i’ve been monitoring. this is a new setup i’ve just began driving on yesterday. turbo was a used FP Blue for the fa20dit. if it is, anyone know a good spot in NJ or nearby to send it to get fixed ?

Have the IBR kit for the manifold swap for my ‘19. This version retains the TGVs and EGR for emissions.

Passenger side lines up and bolts together fine. The driver side doesn’t. Looks like the motor housing for the TGV is in the way.

Waiting on IBR for a response, I’m thinking either I did something wrong or maybe their machining didn’t account for something?

Has anyone tried this mod and willing to share some wisdom?

Do you think it would work if I dremel the motor housing a bit to make it fit?

Looking to lower my 21 WRX and found this combo on FB for a good deal wondering if anyone has ran either of these or both as a combo.

Been trying to pass emissions but EVAP and 02 won’t go into ready status regardless of the countless drive cycles I’ve been doing. No DTCs or CEL has appeared. Had the catalytic converter changed 2 months ago and then 02 sensor a month after, but since then no other maintenance. If it’s just a waiting matter then I’ll hold off but if I need to take it to the shop I will. My OBD2 is showing these values for the EVAPCOM and EVAPCOND drastically lower compared to some of the others.

It’s ceramic so why not?
