AIRESEARCH GARRETT TURBOCHARGER M11 DETROIT DIESEL IL 71 SERIES DIESEL ENGINES. Turbocharger for Detroit Diesel 471T Engines. I was told it was rebuilt, and it looks nice. It does have very little side to side play but not much. Let me know if there is an issue. I sometimes make mistakes, but i’m not out to cheat anyone, or sell you something you’re not 100% happy with. A if you follow the golden rule, and treat me as you would like to be treated, i will do my best to make it right by you.
