It's not necessarily the turbo. It could be a belt. What year car? What mods? What miles?

I started up my WRX this morning, it was sitting outside and it was a bit cold. When I was driving down the road I used the turbo, and it made this high pitched squealing noise that I have never heard before. After a little while of driving it subsided. Is it supposed to do that when its cold?
I just want to make sure its not broken.
No.

It possibly sounds like a small pre-turbo exhaust leak. They will screech during boost when the pipes are cold, then quiet up when everything heats up and expands.
So what does this mean? Is it a bad problem?
Not horrible, but it should be corrected if that's the problem. If that's the problem, the gasket is cheap. It's just labor that could be a few bucks if you can't do it yourself.Originally Posted by glamoureux
what could have caused this to happen, because i didnt even push it hard.
gaskets wear over time, they are usually made of some sort of rubber compound. heat and cold will make them brittle and they will break and leak.
even though you only have 60k and never drive your wrx hard, the car has been on the road for 8+ years, and over that time, the gaskets will wear and need replacement.
its nothing huge to worry about, just maintenence and wear and tear

If literally all you have is what you listed, this car shouldn't be being driven.

It's well documented that in order to upgrade a turbo a WRX requires several things.
Turbo
Fuel Pump (Walbro 255)
Larger injectors (565cc would be ok for a VF39)
Uppipe/downpipe (uppipe only required on 02-05 WRX's)
An OTS map for that turbo/injector set or a custom tune.
why?
it has the top mount intercooler, the up pipe, the down pipe, injectors, STI turbo, STI struts, Exhaust, Blow off valve
