BorgWarner K27 Turbo (53279887200)
Borg Warner Turbos K27 replacement for the Holset HX35W turbocharger.
The K27 turbocharger is capable of supporting diesel trucks up to 450HP. Featuring a 60/83.7mm Forged Milled Wheel (FMW). The 7/7-blade compressor is made to resist low- and high-cycle fatigue. The 70/58.83mm 12 blade Inconel turbine is a made for quick-response. The turbine wastegate housing is a twin-volute, and an adjustable wastegate actuator is preset at 26 PSI (325hp), which is safe up to 40PSI (450hp) with a Power Driven Diesel Turbo Tuner. Like the Holset, the oil inlet is a threaded M12 and oil drain is threaded M8.
1998.5-2002.5 Cummins with a HX35W turbochargers, A Cummins 3927811 cast elbow and 3903652 v-clamp is needed to use you current downpipe.
1998.5-2002.5 Cummins with a HY35W, A Cummins 3927811 cast elbow and 3903652 v-clamp is needed to use you current downpipe. Replacement of the two studs installed into the original turbine inlet flange will also be needed
2003-2007.5 Cummins with either a HY35W, HE351W, or HE351CW a fabricated or adaptor for the compressor discharge and for the turbine discharge are necessary. With a HE351CW turbocharger, a ?boost fooler?, or resistor is also necessary.
Additional Information:
- Max warm oil pressure: 5 bar (73.5psi)
- Max cold oil pressure: 8 bar (118psi)
- When starting a fresh engine build or in extremely cold climates – oil pressure must reach 0.5bar (7.2psi) within 4 seconds maximum.
- Do not load the engine with full boost and WOT until full operating oil pressure is present
- Do not load the engine with full boost and WOT if any boost leaks are present (this can result in turbocharger overspeed)
