Product Description
BorgWarner 177280 S300SX3 Turbocharger — S360/68, 0.88 A/R, T4 Housing (Open Flow)
BORGWARNER 177280 S300SX3 brings a powerful blend: a 60 mm compressor inducer (≈2.36") with a 68 mm exhaust exducer and sturdy journal bearing core. Tuned with a 0.88 A/R T4 open-flow turbine inlet plus a 90-degree compressor outlet, this unit’s built to support high output with excellent response in large displacement or compound applications.
Key Specifications
- Compressor (S360 / 60 mm): 60 mm inducer / ~2.36″, ~3.29" outer diameter wheel
- Turbine side: 68 mm exducer / ~2.66″, 76 mm turbine wheel OD, 0.88 A/R, T4 open inlet
- Compressor outlet: 90-degree elbow / standard 90° orientation
- Bearing style: journal bearing; built for durability and high duty use
Rated roughly for **320-800 HP** depending on setup, fuel, and supporting mods. Verify manifold, downpipe, oil feed/drain, and piping clearances. Open-flow T4 requires proper exhaust configuration.
What’s Included
- BorgWarner 177280 S300SX3 turbocharger (S360/68, 0.88 A/R, T4 open flow inlet)
Recommended Add-Ons
- CPP -12AN Oil Drain Kit (S300/S400 series)
- Fleece FPE-34856 S300/S400 Turbo Stud Kit
- CPP S-Series Compressor Discharge Elbow (4.0″ Hose Outlet)
Build & Fitment Notes
Street / Drag / Compound Builds: Spool is moderate; to get ideal response, pair with a proper exhaust and manifold. In compound setups this works well as the HP side.
T4 Open Flow Considerations: Requires sufficient turbo exit exhaust path and wastegate flow. Compressor outlet elbow orientation can affect clearance in many chassis.

FAQ
Will the 177280 bolt onto stock manifold flange?
Mostly no—the 177280 uses a T4 open-flow turbine inlet. If your stock manifold is T3, or divided flow, you’ll need a T4 inlet manifold or adapter. Downpipe, wastegate path, and exhaust routing must accommodate the larger exhaust flow.
How soon will this spool compared to smaller S300SX or S200SX units?
Expect slower spool compared to smaller inducer units. This 60 mm inducer demands more exhaust energy. Paired with proper fuel system and tuning, it performs very well after mid-RPM and above.
Is the journal bearing core durable?
Yes. Built with journal bearings, designed for performance under high exhaust and thermal loads. Regular oil supply, correct drain, and clean lubrication are essential.
What compressor outlet size and orientation does it use?
90-degree compressor outlet. Verify your charge piping routing; elbow clearance and hose coupling matter.
Is this for compound or single turbo setups?
It works for both. Strong single if you’re doing big displacement or forced induction; excellent as the high-pressure stage in compounds with a matching low-pressure charger.
