Supercharger kit for Honda/Acura K20/24 Engines

  • Capable of over 450 HP system and 500  HP+ with E85+
  • MR1900 TVS Supercharger
  • The system provides increased power and airflow with less blower rpm, thus increasing efficiency 

Boost the power output of your K-Series Honda/Acura engine, while retaining drive-ability, fuel economy, and reliability with this MercRacing MR1900 Supercharger Kit. The kit delivers over 450 horsepower on pump gas and over 500 HP on E85+ fuels. Besides peak horsepower and torque this supercharger offers real “under the curve” power and near instantaneous boost and torque upon demand. The kit not only allows you to keep your air conditioner system but surpasses the power of Rotrex based supercharger kits.

Maximizing your efficiency during cruising is the job of the supercharger’s integrated bypass valve. This vacuum operated system allows air to bypass the supercharger and the rotors to “free-spin” under light engine loads. During this situation the parasitic loss of the supercharger system is essentially negated taking less than one-third of a horsepower to turn the rotors. This bypass valve also allows your supercharged vehicle maintain stock-like drive ability and fuel economy – giving you a package that delivers power without compromise.

Down to the smallest part, our bolt-on supercharger system is engineered as a complete package. The supercharger, supercharger intake manifold, inlet, pulley, and necessary hardware to make installation simple and easy.

The MR1900 TVS technology supercharger utilizes EATON’s latest 6th Generation supercharger rotor technology found in such industry leading performance vehicles. These Twin Vortices Series Superchargers feature a pair of four-lobe, high-helix rotors with 160-degrees of overall twist that are housed in a patented high-flow housing. This highly efficient package requires less power to drive, delivers cooler discharge temperatures, and is much quieter than many of its competitors.



  • MR1900 TVS supercharger kit with 3.2 pulley.
  • Complete Air to Water Cooling system
  • High quality finish CNC inlet – ready for Stock thru 74mm throttle bodies


  • 80-90MM Inlet option available for drive by cable cars. Increases performance incredibly.  Not recommended for those needing easy driving for a daily driver for stop and go constantly.  This increases power output from part throttle to full throttle tremendously.  This is a hard core upgrade that YOU must be determined to learn to drive.  This requires proper tuning if wanting to use on the street to smooth out the part throttle response to your liking. If you don’t know how to tune or do not have access to a responsive/experienced tuner, DO NOT get this for the street.



You must replace the thermostat housing with one that points downwards. Such as the Acura RSX Type S. for some vehicles; such as the Civic 8th/9th Generation.  This provides clearance for the manifold and puts heat away from the manifold.

Part needed:

Thermostat Housing Part#: 19320-PNA-003

Thermostat Part#:  19301-PNA-003

This is a direct bolt on kit for Honda Civic 8th/9th Gen and Acura TSX.

The RSX requires change on the support bar frame to clear the bypass unit. If you have a K24 swap there may be some hood webbing clearance issues you need to address.
