Turbo Help
For the last couple of months my 2003 Quattro TT has been acting fatigued. The turbo feels really delayed and underpowered. When at the top of a higher gear the turbo felt like it was gone entirely. I have put it off as money was tight, but i am wanting to get it fixed now. I took it to a mechanic and after listening to it rev up a few times he told me that the bearings in my turbo need to be replaced and that i was probably running at about 50% power. I am very uneducated on turbo's. I shopped around online and it seems that the only way to fix the problem is to rebuild the turbo for about 400 dollars. Firstly, how likely is it that this is the problem? Second, would it be more ideal to just buy a new, better turbo? I should point out that i AM wanting to increase the power and acceleration in my car, but thought i would start with cheaper mods.

Here are the possible problems:
Boost pressure control swing valve/poppet valve does not close
Dirty air filter system
Dirty compressor or charge air cooler
Engine air collector cracked/missing or loose gaskets
Excessive flow resistance in exhaust system/ leakage upstream of turbine
Foreign body damage on compressor or turbine
Fuel system/injection feed system defective or incorrectly adjusted
Insufficient oil supply of turbocharger
Pipe assy. to swing valve/poppet valve defective
Suction and pressure line distorted or leaking
Turbine housing/flap damaged
Turbocharger bearing damage
Valve guide, piston rings, engine or cylinder liners worn/increased blow by
I would not rebuild but rather replace the turbo.

Ok, why would you replace instead of rebuild, and what turbos would you suggest?

What RPM should the turbo kick in? It feels kinda jerky to me, but then I've never owned a turbo bef
