BorgWarner AirWerks S363SX3 90° Compressor Outlet aka 8776 62.99mm S300SX3 (177283)
The S363SX3 S300SX3 8776 is one of the most interesting and versatile BorgWarner/Airwerks turbochargers available. Using an 87.37mm exducer and 62.99mm inducer compressor, this turbo is essentially a slightly higher performing version of the GT4088R and T04Z. It comes standard as a 90° compressor housing with T4 0.88 A/R single scroll turbine housing. It is easily upgradeable to twin scroll T4 with 0.91 or 1.00 A/R.
The Compressor is a seven bladed 62.99mm inducer, 87.37mm exducer rated at 77 lb/min. Recommended for use in high flow 450-750whp applications compressor housing is a 4″ inlet, 3″ outlet. Due to the extra flow capacity in this turbine wheel, we recommend using the 0.91 A/R for small displacement 4 cyl engines, and the 1.00 A/R for high boost over 26+psi. Journal Bearing and Oil Cooled only (water cooling and BB CHRA not applicable).
