Posting this here as Ive gone through my intercooler piping from the intercooler all the way back to the turbo and found nothing suspicious.


Starting thanksgiving my car started making an odd noise. Sounds alot like the radio frequency interferance you get from an unshielded electric motor or from running copper core plugs and wires. it is NOT coming from the radio. it ONLY happens when the turbo is building boost and seems to be coming from the turbos vacinity.

any input or suggestions/ideas would be greatly appritiated!

You most likely have a leaky exhaust gasket. My bro-in-law's legacy made the most annoying noise under any time of acceleration and it turned out to be because he re-used the exhaust gaskets. I've also done an exhaust swap and heard the same noise with a re-used gasket, it went away once I cinched the nuts down a little more on the downpipe. BUT you don't have to have re-used gaskets for them to leak. Most likely the leak is so small it will be very hard to find but if I were you I'd but out a small pivoting mechanics mirror and a flashlight and check all the gaskets for soot marks.

ps- in my experience it was most often the uppipe-to-turbo gasket or the turbo-to-downpipe gasket.

I think this might have something to do with it >.>

that could possible be it
