The Stage 1 N55 Hybrid is designed for owners who want to maximize the efficiency of their factory turbocharger. By upgrading to a 6+6 Billet compressor wheel and a reinforced bearing system, we increase the airflow capacity and reliability of the unit. This upgrade is perfect for reaching 430-450 HP while maintaining 100% of the factory spool time and response.

Important Note: Please include your VIN with your order to allow us to verify if your specific model uses a pneumatic (vacuum) or electronic wastegate actuator.

Description

Serious Performance Upgrade

The factory N55 compressor wheel is heavy and inefficient at higher boost levels. Our Stage 1 modification replaces it with a lightweight, CNC-machined Billet wheel. This reduces rotational mass, improving response and allowing the turbo to hold more boost at the top end of the rev range. It is a robust, reliable upgrade for those who want a “Stage 2+” feel without going to a full Stage 2 or 3 setup.

Why This Turbo Wins

Consistent 430-450 HP performance
Factory-spec spool time
Lightweight 6+6 Billet compressor wheel
Reinforced internals for higher boost reliability
Cost-effective performance jump

Internal Upgrades

6+6 Billet Compressor Wheel: Lighter and more efficient than stock.
Reinforced Bearings: Prevents failure at increased boost pressures.
Wastegate Repair: Optional repair for loose/rattling N55 flappers (extra cost).

Vehicle Compatibility

BMW M2, M235i, 335i (F30/E90), 435i, 535i (F10).
Please verify fitment before ordering.
