Fits: 2011-2016 GM LML w/ 6.6L Duramax
The stock VGT turbo that comes on your 6.6L LML can become a liability when it's pushed beyond OEM specifications and can cause countless issues. H&S Motorsports has solved this common problem with the 132001 SX-E Turbo Kit for the 2011-2016 GM LML Duramax.
This kit is designed to replace the factory VGT turbocharger with a new BorgWarner SX-E unit to provide not only a significant performance increase but also to gain reliability over the factory unit.
- 0.91 A/R Divided Turbine (Twin Scroll)
- Twin Scroll Manifold
- 73mm Turbine Wheel
- Lower EGT's (170-Degree Drop)
- 60-100hp Gains
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 6.6L Duramax engine. All SX-E turbo options include the .91 A/R divided (twin scroll) turbine housing and our true divided exhaust manifold takes full advantage of the twin-scroll design.
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 170-degree drop in peak exhaust gas temperatures when compared to the factory VGT.
Durability and reliability also play a big part in our 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 WHP (depending on which SX-E option is used). With complimenting fuel modifications, these turbochargers have been known to put down some serious power!
We offer several different compressor wheel options with this kit:
- 63mm Forged-Milled Compressor Wheel (575-625 WHP)
- 64mm Forged-Milled Compressor Wheel (600-650 WHP)
- 66mm Forged-Milled Compressor Wheel (650-700 WHP)
- 69mm Forged-Milled Compressor Wheel (700-750 WHP)
(All of the above options include the 73mm turbine wheel and .91 A/R divided turbine housing.)
