5150 AutoSport VANOS Delete Kit, BMW S54

Currently on backorder, please note 6-8 week lead time.

The 5150 AutoSport VANOS Elimination Kit for BMW S54 is a set of components designed to remove the OEM VANOS system from the S54 engine, which is found in the E46 M3, Z3 M, and Z4 M. 

OEM BMW S54 VANOS Configuration

Our kit includes the components necessary to lock the camshafts in a fixed position, bypass the VANOS control system, and ensure that the engine can operate without the variable camshaft timing feature, making camshaft timing completely customizable.

Why Eliminate VANOS?

Performance Tuning for Track-Prepared Vehicles

High RPM Optimization: Track-prepared cars can benefit from high RPM optimization and fixed cam timing, which is more predictable and easier to tune for specific power bands.

Custom Camshaft Profiles: Some performance tuners may opt for custom camshaft profiles that do not require variable timing, aiming for maximum power in a specific RPM range rather than a broad power curve.

Important Notes on Eliminating VANOS:

It is important to note that this is a modification that is mainly beneficial to cars that are only used for on-track, race applications. Eliminating VANOS results in the following effects, which may not be the best fit for your build. If you have any further questions, consult with your engine builder or work with one of our engine build advisors.

Loss of Low-End Torque: The VANOS system improves low-end torque by optimizing camshaft timing for different engine speeds. Without VANOS, the engine may lose some low-end responsiveness and torque.
Reduced Fuel Efficiency: Variable camshaft timing helps optimize fuel efficiency across different driving conditions. Removing it can lead to increased fuel consumption, especially in daily driving or part-throttle conditions.
Emissions: The VANOS system helps in reducing emissions by ensuring optimal combustion efficiency. Eliminating it may lead to higher emissions, possibly making the car non-compliant with emissions regulations.**

** Please note that the 5150 AutoSport VANOS Elimination Kit is solely for off-highway racing or competition purposes.

Less Versatile Power Delivery: With fixed cam timing, the engine's power delivery becomes less versatile, potentially sacrificing performance outside the targeted RPM range for optimization.
