but if your only spending that much on a turbo setup then you probably wont have a nice rebuilt/forged engine that your putting it on

the ebay turbos just get shaft play in them real quick. lots of people run cheap ebay coolers, they do the job but obviously if you spend a grand on a cooler its going to be better than a $200 one. but then it wouldnt surprise me if you expensive coolers also used cheaper cores and just stamp/paint a brand on them

would only be the exhaust impeller that would be ceramic but then would a ceramic wheel be cheaper than steel one? coz im doubting that it would be. cant say ive heard of a ceramic front wheeled turbo so you wil only shoot an impeller down the exhaust and kill a cat or muffler if it does let go
