I've got 3k miles on mine and don't have any problems. I thought the reason we didn't buy "cheap" turbos was because ours were not easily accessible. I do all my work so I don't have to pay anybody and I could replace them in under 10 hours. Eventually I got tired of the cloud of smoke that would follow me everywhere so I bought the cheapest thing I could afford at the time. Granted if I had the money and my car wasn't my daily I would have waited and bought something better. You do what you love and for me that's driving my z everyday.
