Replacing a stock turbo with high miles with another new stock turbo?

Is there any power to be gained by replacing a turbo with 60k on it with a fresh brand new one? Or as long as there isnt smoke or oil spewing, is there really no reason to bother replacing it?

 

No reason to replace unless the current has problems. Shaft play bad seals etc....

 

a new turbo may result in a slight power gain(1-2hp) due to better flow, but as long as the turbo is working, there is no need to replace it.

 

I got turbo that'll give you some performance gain...

 

ok thanks. I dont think anythings wrong with it. Its just pretty loud since i swapped my uppipe. It even audibly whistles when im in vacuum per my Cobb data monitoring.

 

You probably have a leak....

 

i dont think i have a leak. it boosts 16psi all day long. its not weird loud, but i can hear it.

 

when you swap the up, you should hear the turbo more...

 

^^^^
yes, it is normal to hear it more when you change things out.

 

I don't see how changing the uppipe would allow you to hear the turbo more. Intake:Yes, Downpipe:Yes. Uppipeon't think so. Whistling is a characteristic sound of an uppipe leak. Boosting to stock level with a stock turbo is pretty easy. Even with a leak.

 

then you've never had an uppipe before. Its way louder. It removes all the muffling from the input of the turbo. As it loses the cat.

 

I'd say you have a leak also. Did you replace all the gaskets when you changed the uppipe?

 

How long ago did you install the new UP?
