Chinese turbos don't necessarily look badly made, but its whats inside and what materials its made from that's what counts. The fact it has nothing on it to identify point to it being a cheap copy in my opinion. Like Stevie said... Measure both of the wheels and get inducer and exducer diameters (small and big end of wheel), you'll need to pop off the comp and ex housings but its the only way to get the spec but tbh if its a cheap copy then they're only about £150 new on ebay!
