When it comes to upgrading your turbo, it is never, ever a good idea to buy one used. Especially off Ebay where they say it came off a "used engine with 35,000 miles." Turbos are serious shit. If you are planning on upgrading your turbo, do it right the first time and buy something brand new. That way you know it won't fall apart in 500 miles.

But yes, that is a small 16G turbo which most likely came off an Evo engine. That is a good upgrade, but if you are going to be upgrading your turbo do it with a new one. There are better turbos out there anyway.
