We have performed extensive testing of BorgWarner's new SX-E line of turbochargers and they have proven to be a great match for the 5.9L/6.7L Cummins, 6.4L/6.7L Ford, and 6.6L Duramax engines. All of our SX-E turbo options include the 73mm turbine wheel and .91 A/R divided (twin scroll) turbine housing. The 73mm turbine wheel is larger than we are used to using, but the twin scroll design helps to retain the response and drive-ability in the lower RPM range. The benefits of the 73mm turbine wheel include lower drive pressure, lower EGTs, and more power! During our testing we experienced an average of a 200 degree drop in peak exhaust gas temperatures when compared to most factory turbocharger setups.
Forged Milled Wheels (FMW) are standard on all SX-E turbos and these compressors work in conjunction with the new enhanced covers that feature an integrated speed sensor port and pre-machined boost port. BorgWarner has also stepped up their game with a 6 pad or 360 degree severe duty thrust bearing that is featured in all SX-E turbochargers.
*** Since this includes a brand new BorgWarner unit, any turbocharger warranties will need to be done directly through BorgWarner. ***
