Product DescriptionDue to COVID-19 these turbo kits can take up to 8-10 weeks for delivery.
The DOC Race turbo kit is the ulimate turbo kit for your street machine! This turbo kit currently holds the N54 single turbo HP record at 889hp. 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. It was put to the test by a handfull 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 Tial MVS 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 and connects to your factory or any aftermarket exhaust that accepts factory gaskets. This kit will only fit RWD models.

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.
A good intercooler is recommended when installing this kit if not already done so.
Please select if you have an AUTOMATIC TRANSMISSION. There is a slight modification to the coolant pipe that is needed to work with AT.
