H&S Motorsports 132001 SX-E Turbo Kit 2011-2016 Chevy/ GMC Duramax

The Variable Geometry Turbocharger (VGT) that comes equipped on the 6.6L LML Duramax from the factory can quickly become a liability when it is pushed beyond what the OEM designed it for. Excessive drive pressure and exhaust gas temperature are common issues associated with the factory VGT. This kit is designed to replace the factory VGT with a new BorgWarner SX-E unit to provide not only a significant performance increase, but also to gain reliability over the factory unit.

H&S Motorsports has done extensive testing on BorgWarner's SX-E line of turbochargers and they have proven to be a great match for the 6.6L Duramax engine. All SX-E turbo options include the .91 A/R divided (twin scroll) turbine housing and the true divided exhaust manifold takes full advantage of the twin-scroll design. The 73mm turbine wheel is larger than H&S Motorsports is 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 testing H&S Motorsports experienced an average of a 170 degree drop in peak exhaust gas temperatures when compared to the factory VGT. Durability and reliability also play a big part in their parts selection and BorgWarner has stepped up their game with the 360-degree thrust bearing assembly that is featured in all SX-E turbochargers.

Without any fueling or tuning changes, you can expect to pick up at least 60-100 RWHP (depending on which SX-E option is used). With complimenting fuel modifications, these turbochargers have been known to put down some serious power! .

(All of the above options include the 73mm turbine wheel and .91 A/R divided turbine housing)
