I really really really appreciate this post, I had a HUGE response typed up, but my computer battery died and I lost it all!!! SO upsetting.  It was nice meeting you, even for just a second at the track.  I didn’t mean to be prying at any secrets when I asked what turbos you were running, I honestly just wanted to know because I am a curious guy!  I am sorry you had issue there, hope its something simple like valve float, rather than anything serious.
I had a ton of good points to make about my history as a Mechanical Engineer, my appreciation of all the information you have shared, and such. As well as my dislike of Naudlee and his practices, especially with regard to his bashing of VAST and JHM.
On to this post, the biggest thing I wanted to ask was what exactly is the difference between the China LD turbos and the HD turbos?
Is it the bearings, housings, any other parts? I only noticed you specifically talking about the quality of the “virgin bronze” bearings.  I’ve only had a small bit of research into the manufacturing processes of sintered bronze bearings, but I do know a bit about material quality and scoring resistance.   Is there a specific bronze family that was better than the knock off crap the China turbos used?
Where are the HD turbos from?
Are some of the parts sourced from china, and others to other places?
