Yah, I've always run one on my Garrett turbos. As do my friends. I have 30k miles on the current setup with a .060 holed one. With any higher psi oil system... restricters are considered the norm from all my experience (DIY or bought for journal ones, built in for BB ones). I honestly want to say its just the turbo...
