Features

  • Direct Bolt-On ; can be installed using the original parts, easy and convenient to install.
     
  • Dual ceramic ball bearing
    The low friction allows the bearing to work at much lower required force and gives a boost at earlier RPM.  The ceramic ball is made of  Si3N4 high-precision fine ground ceramic ball. The spherical surface is in a perfect mirror state.  With the match of the high-temperature, wear-resistant, shock-resistant and lightweight retainer cage, our bearings give an earlier boost than other ball bearings !


      
  • The upgraded aero grade aluminum billet compressor wheel allows higher intake air volume and improves air inlet efficiency.


      
  • This upgraded high-flow turbine wheel comes with Inconel alloy; able to withstand higher temperature and pressure.  As to the blade design, it offers much higher efficiency in terms of airflow, smoother exhaust and backpressure reduction.  In return, we have much better wheel performance.



  • The turbine housing valve parts are made of heat-resistant, corrosion-resistant, high-strength alloy, which withstands long-term high temperature and valve opening-closing impacts.
     
  • The exhaust housing is made of high temperature-resistant cast iron. It will withstand continuous extreme temperature and pressure.
     
  • Billet adjustable actuator comes with different springs, able to adjust boost level according to tuning needs.


      
  • Balanced by Schenck balancing machine
    Precise balancing is one of the essential procedures in JP Turbo production. A good balance is always an important factor in having an outstanding performance and reliability of a turbocharger. A good balance can also improve the noise generated by the high-speed operation. We have very strict operating standards for balance.  First, we perform a low-speed dynamic balancing on a high-precision single-piece balancing machine in order to achieve the best balance of the parts. Secondly, we rigorously assemble the CHRA parts. After the assembly is completed, the high-speed dynamic balance is then performed. Our high-speed dynamic balancing machine can reach a maximum speed of 250,000 RPM.  This balancing standard surpasses the OEM standards.  Each turbo is accompanied by a serial number and the balance test result is kept in our database.
