DOC Race is in the process of developing a true bolt on turbo kit which will be available to purchase early 2020.  We  are using Borg Warner EFR which has been proven in the industry to be one of the best performing and reliable turbos.  With this kit you will be able to install and fire up the engine without any additional hardware such as a boost controller or tuner.  Although we highly recommend having your car tuned after installation you can start the car and drive off even with a stock tune.  This turbo kit will run 100% off of your stock DME.

EFR Series Turbochargers

Clean-sheet concepts. Loaded with innovations. Engineered For Racing.
