I said it years ago, ebay no name turbos have their place but if you daily drive your car they dont belong under the hood. That damage you can cause with a failed turbo isnt worth the cost savings for a daily driver. If your building a super budget track car and you dont have to rely on it to put food on the table then go for it, and crank that chinese cheapo up to 11 but I dont like the way cheap parts balance and i dont like the way cheap seals hold.
We have a saying ( Cheap, Reliable, Fast << Pick 2 )
Slow is Smooth > Smooth is Fast
