Description
Elevate your BMW N55's performance with the VTT N55 "GC" and "GC+" Turbocharger Upgrades. Designed to deliver up to 700 WHP, these turbochargers offer a direct replacement for factory units, eliminating core charges and long lead times. Our turbochargers maintain factory-like spool while enhancing power output, thanks to our proprietary VTT design changes.
Our 100% new castings retain the best aspects of the original N55 turbo design while improving on weaknesses such as the factory inlet area, bearing housing oil structure, and thrust bearing. Each component is cast to OE quality, ensuring reliability and performance.
Key Design Elements:
- New castings with factory restrictions removed
- Factory-style inlet; upgrade to high-flow N55 inlets recommended
- 9-blade Mar-M 246 turbine wheel with advanced aero technology
- 9-blade "point-milled" compressor wheel for maximum flow and minimal surge
- Direct connection to all factory lines, including oil, water, downpipe, and charge pipe
- Improved internal components, including upgraded bearing housing oiling and thrust bearing
- No core charges; sold outright
- No long lead times; inquire about stock levels for quick shipping
- Full 12-month unlimited mileage warranty
Turbocharger Purchase Includes:
- 1 VTT N55 "GC" turbocharger
For maximum performance, pair this turbocharger upgrade with complementary modifications such as fuel system upgrades, intake, downpipe, intercooler, and tuning. Gains are achievable with the GC/GC+ alone, but other modifications can help you realize the full potential of your upgrade. Be sure to add an N55 install kit for a smooth installation process.
Fitment:
- BMW N55 engines
