BorgWarner AirWerks S200 SX 7070 aka S251SX (177257)
BorgWarner’s entry level ‘SX-Series’ turbos redefine performance, durability and value for modern turbochargers.
BW utilizes their 70mm turbine wheel with 50.7mm inducer / 70mm exducer FMW compressor in a purpose built S200 SX compressor housing. This is an excellent match for the 220-580hp range (up to 2.6L) or as twin turbos in 440-1160hp applications. Oil-Cooled Journal Bearing only.
This is one of the best values we’ve ever seen in the turbo industry. Designed as a fast spooling and versatile turbocharger, the S200SX compressor uses a 7-blade Extended-Tip design w/ 50.7mm inducer & 70mm exducer rated at ~54 lb/min. 3″ inlet 2″ outlet compressor housing comes standard. The S200SX turbine wheel is a 10 blade turbine with exceptional blade aero, shared with the EFR family. Borg Warner chose the 0.83 A/R Twinscroll T4 footprint to make it a bolt-on for any divided T4 turbo manifold. Ideal for use in quick spooling 220-500+ whp applications.
Full-Race recommends porting the turbine housing inlets to match T4 size openings.
Full-Race Recommends machining the Borg Warner/Airwerks turbocharger outlet and welding on a 3″ Vband flange.
