Okay so I recently picked up an old ls1 fbody sts kit off craigslist for dirt cheap. The seller said he took it on trade and didn't really need it. He said the previous owner told him the kit was 4-5 years old and only used for a very short time (everything looks new). I'm not planning on using the turbo that came with it, but to sell it I figure I'll need some info on it. I'm just wondering if anyone on here might recognize it or simply be able to tell me more about it. Maybe a value even? I don't know a whole lot about Turbos in general so any information would be greatly appreciated. On to the pics:

The letters/numbers on the turbo are A/R .50 and M12






Thank you!
