since he doesnt kno how to exaplin people want to hear. its a T3/T4 with 0 trim. its a garrett turbo. yes its rebuilt. why you ask? well viking and garrett had a mix up with some other parts and he had credit from them and so i told him since you have credit go have it rebuilt.(no it wasnt broken but not many people are gonna buy a used turbo). so it just came in the mail in the box like a week ago and vikings going back to a stock turbo so its for sale.good price considering its a garret never used
