hey what kind of turbo is this? just wondering cause i picked it up for only 15 bucks, so i thought it was a good deal. how can i tell if its good or if something needs to be fixed also. i can only see a small hairline crack on the rusted portion, im not sure what its called. the spool also has almost no play in it, but moves a little.






oh and theres some writing that cant be read in the pictures, but it says something like A/R 0.6...i think
