T3/T4 .57 A/R Turbine .50 A/R Compressor T04E Turbocharger Stage III
  • This T3/T4 hybrid turbocharger assembly is created by installing a T4 compressor wheel and housing onto a T3 turbine housing, wheel and center section.
  • A T3/T4 hybrid turbocharger assembly is a compromise for engines where a T3 turbocharger is too small to reach the desired maximum horsepower but using a T4 turbocharger would create an unacceptable amount of turbo lag.
  • The T3/T4 turbocharger is designed to be used on engines displacing 1.6L-2.5L and is typically good for around 400HP.
  • They are also commonly used in twin turbo applications.
  • In this case those figures would be doubled 3.2L-5.0L engines up to 800HP.
  • Horsepower ratings are generally meant to express the turbochargers maximum airflow capability.
  • Recommended boost pressures are 5psi(.5 Bar) to 20psi(1.5 Bar) and boost pressures should not exceed 30psi(2 Bar).
  • Exceeding 20psi(1.5 Bar) of boost pressure can significantly reduce a turbochargers lifespan.
  • Generally speaking 14psi(1 Bar) is good for a 100% increase in horsepower from a naturally aspirated engine.
  • Also factory non-turbo engines without forged internal components on high octane pump gas (91-92 octane) it is not recommended exceeding 7psi (.5 Bar) of boost.
  • Doing so could result in damaging your engine.
