Anyone have experience with the new CXRacing X Series Turbos
 

With this new X Series, CXRacing is offering billet compressor wheels, dual ball bearings and they claim that they are balanced (/assembled?) in the US. While this is all fine and dandy, it doesn't mean anything if the bearings are crap and the turbo flies apart after 2,500 miles. Does anyone have any more knowledge or experience with these? I have found a distinct lack of info on the web, outside of Stovall's Garage (youtube channel oriented around a Ford Escort).

I did some looking at them when I decided to upgrade from my journal bearing ebay turbo. I found the way they market the ball bearing turbos to be suspicious. It didn't look like any of the typical miata sized turbos were actually X series turbos. They just put an X series blurb on all of the ball bearing turbo pages even if the turbo model wasn't shown as part of their X series.

The guy you linked didn't even get a turbo that matched the advertised specs.

The conclusion I came to is that spending that kind of money on a chinese turbo is stupid. Either you go dirt cheap and get a journal bearing turbo for $150, or you get a used garrett. I now have a used BB garret that cost far less than a new chinese BB turbo.

My understanding is that the X series were the ones that were dual ball bearing with the option of a billet compressor wheel. I agree about the suspicious marketing, it seems that many of the "hybrid" (ball bearing and journal bearing) turbos are marketed as the X series as well.

I guess i just wasn't surprised the the inaccurate specs that Stovall encountered. When buying "Ebay" grade stuff, I think it is only fair to expect something close to what you ordered.

I already have a new GT2560R for my build and at only $150 more than the CXRacing X series stuff, i don't really see a reason to take the risk. I am more just curious than anything else.

He ordered a 3576 and got a turbo that measured as a 3084. That's not even remotely close to the same thing.
