alright I bought a turbo on ebay, the guy said he got it from his local dealer, but I dont know if its real. If its some knock off I dont want to put it in cause it could fail causeing more damage. Is there any way to tell if its a true bog warner?

 

if its a borg warner it will say borg warner and "KKK" or tripple K or something cast into the metal housing. chances are if you bought it for less then $400 off ebay its not a new k03 turbo. its either rebuilt, or a knock off replica.
