We are proud to announce the release of our premium ball-bearing turbo kit with stainless steel exhaust housing for the F3x BMW platforms equipped with N55 EWG engine

We utilized transient flow analysis backed by flow bench testing to optimize turbine housing for a GTX3582R while maintaining stock fitment, stock location, and using the stock waste gate (this is not a stock turbo with a bigger compressor wheel). This allows to run any stock fitment exhaust downpipe, intake and charge pipe.

You can simply transfer your factory wastegate, your high performance downpipe, intake and charge pipe during the install.

Features:

• Complete brand new turbocharger; no need for core to be sent it or purchased
• GTX3582R-style Gen2 ceramic ball-bearing CHRA (dual ball-bearing)
• Billet 10-blade compressor wheel
• Proprietary stainless steel turbine housing, flow matched to the turbocharger
• VSR Balanced to exceed OE tolerances
• Oil and water fittings included
• Compatible with factory installation hardware (not included)
• Compatible with factory wastegate actuator (not included, use your original wastegate actuator. Actuator must be calibrated during installation. 90% WDC max)

What's Included:

• CTS Turbo BOSS Turbo Upgrade Kit

Fitment Details (fitment for EWG electronic wastegate only):

• F30 BMW 335i & 335xi (production date after 07/2013)
• F32/F33/F36 BMW 435i & 435xi 2013+

READ:

**BIG TURBO SOFTWARE TUNING IS REQUIRED VIA ECUTEK PLATFORM, FUELING UPGRADES ARE RECOMMENDED. PROFESSIONAL INSTALLATION AND TUNING ARE REQUIRED.

WASTEGATE MUST BE CALIBRATED WITH ISTA+ BEFORE TUNING. FAILING TO DO THIS WILL CAUSE PROBLEMS WITH TUNING.

THIS TURBOCHARGER IS DESIGNED TO MOVE A LOT OF AIR AT FAIRLY LOW BOOST. MAX BOOST LEVEL IS 20PSI.
