Easily the most iconic turbo of our generation, the BorgWarner S400 is now being produced at BorgWarner's facilities overseas. Changes are subtle, and majority of the dimensions appear majorly unchanged, but there are differences! We explore the new Chinese made 171702 and compare it to its US built brother.
When it comes to turbos, the 171702 is the BUSINESS. Originally released as a bolt on upgrade for 12.7L Detroit engines, this turbo can be found on Cummins, Cats, and even LS engines! Hands down one of the most popular turbos in the aftermarket industry due to its low cost and versatility among so many platforms. Once a plentiful turbo found in every BorgWarner warehouse, these things have become scarce and hard to come by due to severe supply chain issues.
