Hard fitment gate — 500-550 hp rating:

171702 is for the 500-550 hp 12.7L. It can replace the 470 hp version (BorgWarner 171701), but the 171701 can’t replace this one. Other 12.7L ratings and EGR engines use different turbochargers — confirm your Detroit number and rating before ordering.

Installation: use new gaskets (BorgWarner kit 318417), set the compressor and turbine housing orientation to match your installation before tightening, and prime the turbo with clean oil before start-up.

Upgrade option: BorgWarner 1496-988-0029, with a 76 mm forged milled compressor wheel and 360° thrust bearing.

BorgWarner 171702 is the genuine new S400 turbo for 500-550 hp Detroit Series 60 12.7L engines, replacing Detroit 23518597 and Garrett 466713-0005. It also replaces the 470 hp 171701, but not the reverse.
