Things To Consider When Purchasing A New Turbo

When you decide that you need a new turbo,  you will need to consider:
  • Replacement or Upgrade?
  • My budget?
  • Street, track or both?
  • Quick spool (street friendly - minimal lag) vs. Max power (more power & more lag)
  • Is it C.A.R.B. certified (for California customers) **

When Replacing the Turbo After a Failure

  1. There are many precautions that need to be taken - especially if you are replacing a failed turbo
    1. Read the product pages carefully - they contain a lot of important information.
  2. 2. Select turbos based on the engine type in your MINI Cooper S. 
  3. 3. Production dates and corresponding engine types for JCW models are different from Cooper and Cooper S models. 
  4. 4. Refurbished Units are completely overhauled including replacement of all internal wearable items such as Turbine Shaft Bearings and Steel Thrust Plates. After the rebuild all internal components are triple balanced which is one step better then the manufacturer's dual balance process.
