Our RPM-K04 turbocharger is the perfect solution for those who want more airflow with out having to swap half the turbo system on their car. Our big wheel RPM-K04 is designed to easily replace your OEM K04, as a complete drop-in unit.
Capable of achieving an additional 30-50 peak Wheel Horsepower without the need to raise boost pressure. This upgraded turbocharger makes even more gains above 5,000rpm, which is typically where the stock K04 runs out of ability to keep up.and HP/TQ drop…
The RPM-K04 Difference:
This is not just a “Big Wheel” Swap utilizing the stock compressor profile… We designed this Turbocharger from the ground up to achieve a maximum of 38lbs per min of Airflow (Stock K04 typically will see a maximum of 32lbs per min).. The billet compressor wheel was designed for our application and are cut specifically for our application and solely for RPM-Motorsports. Our 30year master turbo builder re-profiles the factory K04 Compressor housing to accept the larger proprietary RPM Billet wheel… and this make all the difference and why our upgraded RPM-K04 is 400hp Capable on a 2.0L DI motor.
