BorgWarner AirWerks T4 S475SX3 aka 10083 75mm S400SX3 (177101)

BorgWarner’s 75mm S400SX3 turbocharger is one of the most potent 75mm large-frame turbos available. This design pairs a 100.17mm OD FMW billet compressor wheel with a high flowing 83mm S400SX3 turbine wheel.This combination provides huge exhaust flow energy without restriction. Bolt-on for many twinscroll T4 manifolds and 4″ downpipes.

BorgWarner’s S400SX3 75mm Turbo Features:

• 5.0″ inlet / 3.5″ outlet compressor housing
• All-new severe duty 360 degree thrust bearing
• Interchangeable with existing turbine housings
• 83mm turbine wheel

The compressor stage starts with a ported shroud housing, including integrated velocity stack. Compressor wheel is BorgWarner’s “FMW” forged-milled-wheel (AKA forged-billet) and uses the latest generation blade aero to reach 100 lb/min max compressor flow. This is a journal bearing oil cooled only turbocharger ideally suited to competitive drag racing.

Additional Information:

• Max warm oil pressure: 5 bar (73.5psi)
• Max cold oil pressure: 8 bar (118psi)
• When starting a fresh engine build or in extremely cold climates – oil pressure must reach 0.5bar (7.2psi) within 4 seconds maximum.
• Do not load the engine with full boost and WOT until full operating oil pressure is present
• Do not load the engine with full boost and WOT if any boost leaks are present (this can result in turbocharger overspeed)
