new turbo, advice needed

[rob turbo]

so, as a silly question, what is the real difference in buying a cheap turbo to one thats nearly a K, lets say a GT30/35.. then, they all do the same job by basicly blowing air into the engine, can any one advise.. im looking at a cheap one myself..

prbley the quality of the metal, casting, and assembly.

The GT3076R spins up to 145,000 rpm.

So when you try to save costs, any imbalance on really cheap bearings will fail alot early than the finely balanced Garrett unit with much more expensive bearings.

The castings probably don't make much difference though unless they're reallllly crap.
