$450 chinese turbo and 600 plus HP(food 4 thought)

I read an interesting article in one of my magazines were they built a 600 plus HP stock 350 with an ebay $450 chinese turbo.They got the motor from the bone yard with 160K on it. I think they were getting 5000 to 10000 miles out of the bearings.in the turbo(bearings being the weak link)
I could post the article if anybodies interested?
I wonder why they didn't upgrade the bearings? The article said other than the bearings not being the best the units were pretty substantial

If your Drain for the Turbo is not up to par you could damage the turbo and have early failure. The turbo's I am using are bought off ebay. Everyone was saying they would never last. I did a bunch of research and all the people that said they would not last were never the end users. Matter of fact I could not find a single end user that had a failure with them. Kind of weird....

Here is a BB 468 CI Chevrolet that has been running for 5 seasons now without any problems at all. Runs 8.8 in the 1/4 at 158MPH also.

I talked to this guy and he said that Failure with any turbo is usually linked to drainage.
