Hi guys, I'm sorry dont have any pictures, but I was just curious as to what kind of turbo my friend is trying to sell me. Apparently he got it from south florida performance, and the markings on it are as follows:

on the intake side it says: 70 a/r m24

on the exhaust side it says: precision .58 a/r

The only things i can gather is that its probably an sc series turbo , but can anyone tel me more specifically what type it is ? e.g. sc34, sc61 ? thank you.
