BorgWarner’s 71mm S400SX3 turbocharger is one of the highest bang-for-the-buck large-frame turbos available. This design pairs a high flowing 83mm S400SX3 turbine wheel with a 100.17mm OD AirWerks “S” generation compressor wheel with Extended Tip Technology for the ultimate in aerodynamics, low RPM spool-up & high RPM horsepower output. This combination provides huge exhaust flow energy without restriction. Bolt-on for many twinscroll T4 manifolds and 4″ downpipes.
