Product Description
BorgWarner 177283 S300SX3 (S363/68, .88 A/R, T4) is the classic AirWerks mid-frame that blends fast spool with serious top-end. Built on BorgWarner’s proven journal-bearing core, it’s a go-to single for street/strip builds or a high-pressure unit in S300/S400 compound setups.
Fitment & Use
- Flange: T4 divided (twin-scroll); verify manifold and downpipe geometry.
- Charge Air: 4.0" comp inlet / ~2.5" outlet (typical S300 cover sizing).
- Oil: -4AN feed, -10AN/-12AN drain recommended; ensure proper routing and return angle.

FAQ
Will this bolt to my factory manifold and downpipe?
No. This turbo uses a T4 divided inlet and requires a matching T4 manifold and appropriate downpipe connection.
Is the 177283 wastegated?
No. This S300SX3 configuration is non-wastegated; boost control is typically managed via drive pressure, turbine A/R, and tuning.
Can I run it as a high-pressure turbo in compounds?
Yes. The S363/68 with a .88 A/R T4 housing is a popular high-pressure unit when paired with an appropriate S400 atmospheric turbo.
What supporting parts do I need?
At minimum: T4 manifold, correct downpipe/v-band adapter, oil feed/return lines, and charge-pipe couplers sized for the S300 cover.
