BMW N55 STAGE 3 TURBO KIT
Manufacturers Description:
We wanted to create the ultimate daily driver turbo kit.
OEM reliability. OEM driveability.
600whp. Full boost by 3000rpm.
Cast Manifold
At the heart of the N55 kit is our ceramic coated cast manifold. Starting with a blank slate in CAD, we were able to design a manifold that will produce awesome spool, and big hp... all while keeping optimal reliability (no welded joints to fatigue crack over time).
BorgWarner EFR Turbo
BorgWarner’s EFR turbochargers set new world standards in performance, convenient installation and high-tech features:
Ultra low-mass Gamma-Ti turbine wheels
Mixed-flow turbine blade design
Dual ceramic ball bearing cartridges
Aluminum bearing housing
Stainless steel turbine housing
Flexible orientation compressor cover
Forged milled compressor wheels
Integrated high-flow wastegate, boost control solenoid valve, speed sensor and compressor recirculation valve
Options for turbos are:
7064 (up to 520whp)
7670 (up to 620whp)
8374 (up to 750whp)
9180 (up to 900whp)
Factory Fit and Finish
The kit was designed to not only make power, but also be efficient and reliable. As such, we designed for it to interact with the stock components such as the airbox/filter/tube/intercooler/exhaust. With just our kit installed, and extra fueling, we've laid down 680whp... through the above stock components. Form and function living together... and making big power.
