If your looking for upgrades speak to flea about the billet wheels he has been getting made there meant to be very good and he also prefers them to the gtx wheels for a few reasons but ask him to explain them.

This china turbo has nothing to do with original GT2871r , not just bearings realy. If its starts to smoke, parts are ready to throw into bin. No wasting money on new bearings(thats only half of parts which are worn). This china crap have very old TB04B compressor wheel, which makes very slow spool and even you will spool it on high gears, it surge as hell. Wheel is also large itself, so machining compressor wheel for another better spooling wheel is impossible. And also cost too much. My experience from 3 cars of this product.
My suggestion with limited money, is buy better designed(mainly not with this compressor wheel, and with .64 turbine housing) china GT2871, test it as it or mount new bearings+360 and rebalance it.
If you have some money, you are mechanical skill limited, buy one of FC pref. hybrids. You want tune from him, he give you best advices, no doubt.

Cheap turbos or Chinese copies, generally have poor quality of materials, but with a restrictor oil can last a lot more miles

Yes, sorry. The turbo shop said that they saw many Chinese turbos but this one was definitely the cheapest copy of all. It was rebuilt with Mellet parts and sold to recover some money which I can now put towards a purchase of proper turbo.
Edit - this copy has nothing similar with a GT2871r. It is a mix or rather miss match of different turbochargers. There are decent Chinese turbos out there but the one from turbo-parts.de is definitely not one of them.
