You need to try another dealer, some of them are lazy or do not really know much about the evo. After calling corporate they assigned me a case number and followed up and made it a point to know which dealer i was taking it to so they could notify the service manager to take care of my situation.

Regarding mechanical issues, i didnt notice any major issues, apart from a really noisy wooooo noise especially when its cold. I have a third party warranty though costco and they wouldnt cover the turbo because mitsu has a factory warranty in place up to 60k miles as its part of the powertrain/exhaust

Also if they try to tell you that its normal, try to get the service guy to ride with you in a new evo on their lot to show them that there IS a difference in the noise.

The corporate rep told me to do this as a followup to the dealer who said it was normal. They said if it makes the same noise on a new car then its normal if it doesnt then it means it needs to be worked on.

The dealer definitely isn't replacing my aftermarket turbo, lol.

sounds exactly like the rest of yours, perhaps a little quieter, I swear I was swivelling my head like a freak. Just got my car back from some routine maintenance and a new brake booster and heard this for the first time. I've had this turbo for some time now.

so none of these turbos has grenaded yet?

I guess, I'll just cross my fingers and pray.

--Do a complete visual inspection
--Is your FPR hose connected, vac lines from turbo, wg, EBCS, and intake? How about pcv vale? All the couplers snug? Anything loose or move excessively? Nothing caked/clogged on your airfilter right? Check all your fluids.

--Check your WB AFR gauge, are your AFRs good? (don't have a gauge...get one, its more important that boost IMO)

--Check your boost gauge, what's your vac levels at idle. Is your engine stumbling as it idles.

--Datalog your car, is it seeing lots of knock?

If all those steps and you still don't see any problems...then follow the previous advice that maybe you're being overly sensitive...and double check that by having a trustworthy friend take a look at things.

if all is good after that, then relax.

Its hard to hear a leak when doing a boost leak test without the engine running. With the engine running and the turbo spooling, the exhaust and numerous other operational sounds will drown it out.
