  1. Maintenance, service, and repair
    So a little back story, my car started to smoke in October 25 to 26, i ask a friend who knows everything subaru and he said turbo seals. So i bought a new turbo and put it on triple checked every hose and line, good. Prime it good, then start it and its still smoking. But the thing is its hard...
  2. Engine Modifications
    I bought a 2008 wrx about 4 months ago without the sellers having any knowledge of what was done to the car, turns out that it was an absolute steal because of that one reason. But without the owners not knowing what was done to it, I know very little about what is done to it internally. I know...

    I'm trying to figure out how to make my turbo louder because I'm seeing videos of wrx's just idling and I can hear the turbo spooling from the exhaust. I've done pretty much everything that I can do to get that signature turbo noise. I have a bigger turbo, turbosmart compgate 40 external...

    The owner before me obviously did some adjusting of the actuator arm because I found out they had the T hoses backwards, broken bolts on the heat shield, and it's just obvious they were in there at some point trying to raise the boost, or had a "sports car" mechanic that was lost on Subarus. So...

    Hello Everyone! I'm new here, and new to the WRX fam, but I'm very interested in upgrading a few bits of my car to take her to the next level. I live in southern Maine (New England - rough winters) and I want my suspension to handle the bumpy roads a bit better, but not feel like I'm suddenly...

    When in boost I hear a loud groan coming from the engine bay. This could be linked to the code that got thrown on the other day (PO244) for turbo wastegate solenoid. Light turned off and back on, I think it may come on because I am overboosting (new to stick shift) which I read on another forum...

    Hi all, I have an 03 WRX that is bone stock and had a code p0420 for bank 1 cat. I changed out the downpipe/stock cat with a Bosal "oem" cat. Looks to be pretty much the same minus all the heat shielding the factory cat has. I also put on new multi layered steel gaskets to ensure the whole...

  10. Motorsports Talk
    Hi. So I just recently bought a 2011 WRX, doesnt seem to have many issues whatsoever but I recently got a check engine light. It was towards the o2 sensors so me and a buddy of mine who knows wrx’s pretty well jacked up the car and tried diagnosing it. Nothing seemed too bad but we decided to...

    What's up all. I just bought my first manual car this week, and it happens to be a 2019 STI with 5 miles on it. A dream. I'm new to this whole scene before this, I had an 03' BMW 325i, so I somewhat know my way around the engine. What I don't understand is how a turbo works while driving...

    So the problem is that whenever I try to hit boost 2500-2800rpm my car jerks back and forth slightly. I can hear the turbo spool really loud but it does not generate any noticeable power. I originally thought that is was because I had a blown HG, but I just barely finished my motor rebuild a...

    Just like it says, if i'm driving and shift at like 3-3.5k (i usually shift at 2k) or let some boost build up, as soon as i go off throttle and on the clutch i hear a "PPFfffffffffwhoosshh" kinda sound, kinda sounds like a cheap BOV but it's all stock, so i thought "hmm it recirculates not...
