The DOC Race turbo kit is the ulimate turbo kit for your street machine! They come complete with all nessary hardware to install and is listed below. The kits come with Precision turbos because they are leaders in the industry for offering top performing products that are reliable so you can make good power and not have to service your turbo for years to come. You can choose from your choice of a 5862 up to a 6870 with horsepower ratings from 640hp up to 1100hp (ratings below).
Included is a T4 twin scroll manifold which is the heart of this turbo kit. Our manifold has been redesigned (9/20) to now be a one piece design for ease of installation. It was put to the test by a handful of very high performing race cars before attempting to fit to our test car. With the design it is capable of producing well beyond 1000hp for anyone looking to really push the limits of this platform. To control all of this, boost is regulated by a pair of Turbosmart 40mm wastegates which are mounted down low and out of the way of heat. The wastegates can be accessed easily without taking out any hot exhaust parts. This will come in handy if you ever need to change springs in your wastegates on the dyne or after hard runs.
Boost is fed to the intercooler by a single 2.5" aluminum charge pipe. The downpipe is made of 3" stainless tubing in two pieces which is V-Band andconnects to your factory or any aftermarket exhaust that accepts factory gaskets.

* Factory fuel injectors will support upwards of 550hp. It is advised to use an aftermarket port injection system when going beyond that level. We suggest an AD-Engineering port injection kit which include additional fuel injectors to support the power level this turbo kit is capable of. This is the system we run on the DOC Race car and is driven daily without any sort of stalling.
* As of 9/20 our kits come with the most updated O2 placement to help with burning out O2 sensors.
No the kit does not come with a MAC solenoid and is not required for an install. It is only required when you are wanting to change boost settings with a tuning device such as JB4 or Motiv boost box.
Is it required to remove the subframe to install the kit?
It is not required to remove the subframe to install the kit. For our one piece design manifold you will need to lift the motor approximately 2" and install the manifold from up top.
What other things should I plan on purchasing when installing your kit?
As with any build you should think about the supporting mods required for your individual power goals. Supporting intercooler, chargepipe/BOV Combo, Fueling, Clutch, Tuning Software MHD/JB4, established tuner and if you're smart.. fresh brakes, tires and any needed maintenance. The 2 items below are what we suggest you replace as preventative maintenance.
