This is a New BorgWarner 2006+ Mini Cooper JCW Turbo Upgrade 53039880146


BorgWarner?s K03-2074 turbocharger (part# 5303-988-0146) is engineered to be a reliable and high-performance bolton upgrade turbo for the 2006+ Mini JCW (up to 255hp).

Mini John Cooper Works upgrade from BorgWarner AirWerks features

  • High temperature alloy turbine housing
  • Extended tip compressor wheel
  • Twin scroll turbine housing
  • Water cooled bearing housing

Using a high-flow twin scroll turbine housing combined with BorgWaner?s extended tip compressor wheel design ? this turbocharger delivers early spool and outstanding boost response with torque and power gains across the powerband. Full-Race recommends the addition of an aftermarket exhaust system to compliment this turbo, although that is not required for the installation.

Additional Information:

  • Max warm oil pressure: 5 bar (73.5psi)
  • Max cold oil pressure: 8 bar (118psi)
  • When starting a fresh engine build or in extremely cold climates ? oil pressure must reach 0.5bar (7.2psi) within 4 seconds maximum.
  • Do not load the engine with full boost and WOT until full operating oil pressure is present
  • Do not load the engine with full boost and WOT if any boost leaks are present (this can result in turbocharger overspeed)
