Features of our turbo kit:

  • Uses Borg Warner EFR Turbo (Engineered For Racing).  We use the best turbo on the market today.  Do not be fooled by other companies that use cheap overseas made turbos to cut cost.  DOC Race uses the best brands because we know our customers demand the best!  More info on EFR Turbos here
  • Integrated OEM wastegate actuator.  No messing around with external wastegates with vacuum lines that could potentially melt!  We all know what a headache it can be working with tuners that can't code out faults related to aftermarket wastegates.  Our kit uses the OEM wastegate actuator so your DME (ECU) won't even detect you have an aftermarket turbo kit installed.
  • Use off the shelf (OTS) tuning maps.  You can use MHD maps just like you would with a stock turbo.  We have tested OTS maps on our development car and it runs flawlessly.  Although we always recommend getting your car tuned by your tuner you can always run OTS maps to get you by.
  • 3.5" stainless downpipe.
  • Use of a shorty air filter.
