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 driveability 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) is 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. ***
