The BorgWarner AirWerks S258 SX-R SuperCore (part number 12707105086) is a high-performance turbocharger core assembly designed for enthusiasts seeking maximum power, reliability, and efficiency. This advanced supercore supports up to 775 horsepower and flows 76-77 lbs/min of air, making it ideal for high-output performance applications.

Key Features:

• 58mm inducer, 76mm exducer forged milled wheel (FMW) billet compressor wheel with black anodized finish
• Advanced compressor aerodynamics with extended-tip technology for optimal flow and reduced inertia
• 69.56mm turbine wheel inducer with 61.43mm exducer for responsive exhaust flow
• Integrated speed sensor port and pre-machined boost port on compressor cover
• 3.5-inch inlet and 2.0-inch outlet compressor housing with port shroud map width enhancement
• Interchangeable with existing S200 SX and SX-E turbine housings (turbine housing sold separately)
• Journal bearing design with 1/4-inch NPT oil inlet and standard T3-T4 M8x1.25 oil drain
• Made in USA at BorgWarner's Arden, North Carolina facility

The S258 SX-R represents the latest evolution of the proven S200 platform, combining the affordability of the AirWerks line with advanced technology from BorgWarner's EFR series. The reduced rotor inertia delivers faster spool-up and quicker boost response compared to similarly sized turbochargers. This is a supercore assembly only, which includes the compressor cover attached to the cartridge, mounting hardware, clamp plates, cap screws, and gaskets. Turbine housing must be purchased separately.
