cypher0117 Posted October 17, 2011 Share Posted October 17, 2011 Feel kinda dumb for asking this but do the 2.5 turbo engines all sound really choppy around 3k rpm and light throttle? Honestly...I might just be paranoid right now as I just finished major maintenance (clutch job). Well, I finished it 2 weeks ago. But since then I've been listening close to make sure I buttoned up everything right. ~850 miles later I am making this (hopefully not useless) post. Maybe it's because I've never really driven the car as light as I could. I'm doing it now for the new clutch. Anything more than light throttle and I can't hear the choppyness. I can hear it fairly well on the freeway cruising with the engine speed around 3k. Here is a sound clip: http://s5.photobucket.com/albums/y156/Cypher0117/lgt/?action=view¤t=noise.mp4 Let me know if this is another quirk that these engines are known for or if something is wrong...

Drakien Posted October 17, 2011 Share Posted October 17, 2011 I have a slight stutter at around 3k RPM at part throttle. At the same time, at full throttle 3k is when my turbo really spools up. Might be coincidence? I will take a closer listen to it and see if it makes that same sound and let you know. Link to comment Share on other sites More sharing options...
frank_ster Posted October 17, 2011 Share Posted October 17, 2011 put a 1/2" threaded into a 1 pint tin can and roll it around and that's the sound of a brand new subaru at cold start Now that's thinking out of the boxer! fyi all 05 + legacy's have built in code reader Link to comment Share on other sites More sharing options...
Strizzy Posted October 17, 2011 Share Posted October 17, 2011 Sounds like normal inefficient Subaru unequal length headers to me. Do you have any mods? My bad luck build Link to comment Share on other sites More sharing options...
BAC5.2 Posted October 17, 2011 Share Posted October 17, 2011 Normal. I think the noise is a combination of AVCS and header design.

cypher0117 Posted October 18, 2011 Author Share Posted October 18, 2011 I put the clutch in 2 weeks ago. And that is around when I noticed the 'new' noise. The sound is easy enough to ignore, it just sounded different so I thought I'd pose the question to the forums. Don't want my engine to explode. On a side note...I did notice very slight shaft play in my stock turbo at 70k miles. I doubt that would have anything to do with this noise though Link to comment Share on other sites More sharing options...
