age??? not really sure. i think it cameas par of a kit for smallbock chevys.. an accel supersonic to be more specafic. it had and adapter the fit inbetween the carb and the intake. it had a "priority valve system" which i have no idea was other then a way co control boost since there is no waste gate onthe turbo i do have the adapter but the valve system is gone so it was running unregluated onthe v8 when i got it
i do know they had it rebuilt by western turbo before they put it onthe truck. and it wasnt onthe truck very long couple months and it was just a wheeling rig trailered there since it couldnt drive on the street with out boost control.
so all said and done... less then 100 mile after a rebuild its in great shape no play... exhaust housing isnt pitted..
that answer your questions?
