The 171702 has long be the raining champion of cheap, reliable, performance turbos for the commercial truck market. Our pals at BorgWarner have taken note to the most common upgrades made to their turbos, and decided to do it themselves from the factory!
The new BorgWarner S475SX-E is everything a 171702 is, but with a billet 10 blade compressor wheel & a 360 degree thrust bearing. This turbo will be slightly more sluggish on the bottom end, but should really come alive in the upper RPMS.
