The Comp Turbo CT4 T51R Mod Compressor Housing is a replacement compressor cover designed for compatible CT4/T51R turbocharger setups. It is intended to manage and direct compressed air from the turbocharger into the charge piping while supporting high-performance and high-boost applications.
The housing features a T51R-style compressor outlet design, giving the turbocharger the distinctive T51R sound often associated with a loud, aggressive compressor surge or “jet” noise during throttle lift. It is built for performance-oriented turbo systems and may be useful when upgrading or replacing an existing compressor housing.
