Regarding the alternator problem. I had a similar issue, but mine was over charging intermittenly. I hooked up a multi meter and watched as I drove to confirm. Replaced the alt with a Bosch. Took me about 2.0 hrs, very easy job. First time doing a turbo too. 1 year warr as opposed to 90 days from a rebuild. 2k miles later, no problems...
