CX racing GT45R Failure Juts finished up my build in my cts V. Here's a link to my build
https://ls1tech.com/forums/forced-in...rbo-build.html
Have less than 100 miles on it and the turbo has taken a ****. It went to squalling and the best I can tell iy has locked up. Ill know tomorrow when I pull it. I've checked the oil feed and have oil going to the turbo. I run the restrictor that came with the turbo. I think its .035. Not sure what went wrong, I dont think it was the fault of the turbo, but maybe I didn't have enough oil flow. Any ideas?

Check the oil and see if its clean,how did the motor run before the turbo locked up? Was it smoking out the pipes or anything abnormal for a warning sign things were going wrong?

I haven't measured the restrictor hole size but it looks to be about .060.
Tore the turbo apart.... looks like it was getting good oil flow,maybe. shaft is bent and bearings are fried. this turbo has a journal bearing on the exhaust side and a cheesy looking ball bearing on the compressor side.

Your "ball bearing" turbo is likely journal bearing, and should not have been restricted.

At all? It has a .060 restrictor that came with it that I used. I took the the turbo apart it is a "ball bearing" but only on the compressor side( a little thin thing that is missing a ball bearing and looks to have came that way) they thinned out that part of the shaft tp put it in. The design looks horrible to me I think I would have been better if they hadn't put a BB on the compressor as I think that is what caused the issue. Comp wheel hit the housing and bent the shaft.

Glad to hear (read: sarcasm) since I'm in the middle of a build using a CX Racing T76 "ball bearing" turbo...so now you got me thinking whether i should run restrictor or not with a journal bearing turbine and ball bearing compressor side...
Make sure all the bearing is there lol.

A buddy had a manual with a pic of the bearing and you are correct, they do come like that so I must have had an oiling issue.
