New N54 Stage 1 Turbocharger Upgrade 135/535/Z4

Product Details

Vargas Stage 1 N54 turbochargers are brand new and include all housing, wheels, and internals. These are brand new units and thus do not require a core charge, making the process easier and simpler.

All VTT turbos come with a performance TD04 upgraded thrust to extend the life of the turbochargers. The stock thrust system has shown to be prone to failure and upgraded thrust parts were created to remedy this.
The upgraded thrust option consists of an upgraded thrust bearing and a 30% increase in surface area on all complimenting thrust pieces.

Every VTT Stage 1 upgrade includes a Billet VTT Compressor wheel. These are fully forged billet wheels, utilizing the ultra-efficient 6×6 blade HTA wheel design as well as extended tip technology to increase airflow a solid 20% over the cast 14T wheels.

The use of an aluminum aftermarket charge pipe, and BOV combo is always recommended with upgraded turbos. Add the  VTT Cold side Charge pipe, and Turbosmart Raceport BOV to your order for just $349! Please see our BOV article for proper installation to avoid compressor surge!

Upgrading your PCV valve is always recommended at the time of turbo upgrade or replacement, as the stock valve can be worn. This means it can stop functioning to its full potential, causing oiling issues with your BMW. This upgraded valve not only replaces the worn stock valve it is also much stronger and will help eliminate any future PCV issues.

Not for sale or use in the state of California on any pollution-controlled vehicle as per the California Air Resources Board.
