Broken ct20b and 93+ turbo rear brake calipers

ct20b - $100 - bought from a member on here maybe 10 years ago but found it didn't boost once I installed it. The turbine looks ok and there's a bit of shaft play but not major. It makes a whining noise when it should produce boost. The boost gauge changes from showing vacuum to 0psi when it's boosting. I don't know what's wrong with it, should at least be good as a core.


93+ turbo rear brake calipers - $100 - also bought from a member here but were never installed. They've been sitting for years so not sure of their condition.

I'll update this post with links to pictures later today.
