Garrett GT4708 Turbochargers

What the Garrett GT4708 is

The GT4708 is a large Garrett frame used on Detroit Diesel and Caterpillar heavy engines. Distributors list GT4708BJNS turbos for the Detroit Diesel Series 60 14.0 liter from 1999 (707866-5008S, 600 hp, wastegated) and its marine version from 2001 (707728-5004S, free floating), and a GTB4708 for the Caterpillar C32 industrial engine. Sellers do not agree on the name: the remanufactured 707866 is listed as a GT4702, and an earlier Series 60 turbo (704122-5001) is a GT4702BJNS.
