The DOC Race turbo kit is the ultimate turbo kit for your street machine!  They come complete with all necessary 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 Turbo smart 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 and connects to your factory or any aftermarket exhaust that accepts factory gaskets.

6466 GEN2 CEA- 900HP
6766 CEA- 935HP
6870 GEN2 CEA- 1100HP

 * 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.

FAQ:

Does the kit come with a MAC solenoid?

  • 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.

SPOT Bungee Raccoon
Purchased 5/20. Decent dog toy. I have a Chiyorkie and he chews on his toys constantly. The squeakers went after a couple of days and then he pulled them out. I put them in the trash. After about two months he had chewed off the head and pulled the bungee out. The bungee went in the trash. I let him play with head and tail pieces for a while but the head had gotten into bad shape so in the trash it went. That left about a twelve inch piece left. He has been playing with that now about a month. He loved tearing the toy up and I do not really blame the toy. He rips up anything that is made of cloth. The only real issue I have with the toy is the two squeakers. IMO they could cause a choking or bowel blocking hazard. I just happened to catch him chewing on them after he had gotten them back. An old knotted on each end knee sock works just about as well but from then on don't leave your socks laying around. They will be fair game for you pet. lol

Fun but.... doesnt stand up to hard play
A very fun toy. My dog loved it - short term. The bungee broke on Day 1 from pulling. (It is designed to be a tug toy, so I assume it should have lasted longer). After a couple weeks, my dog had pulled it apart. Super fun toy, but not for hard play.

Durable against many rounds of zoomies
Strong bungee cord for sure, and my pup really likes pulling on it and playing tug with it. Originally bought it to encourage him away from underwear and socks, which almost worked. He likes chewing on the feet of the raccoon, so they’ve come off, but the lack of stuffing is wonderful. This is one of the longer lasting toys he’s had, and he’s had it for a couple of months, with its functionality still 100%. This seems to be almost like a toy within a toy, as you’ll still have the band when the rest is gone. Worth the money.

Cheap, and durable!
I bought this toy as a cheap temporary toy for my Rough Collie. Well, a month or so later, it's still alive. She has performed a 'squeakerectomy' on it, and it's lost it's springiness, but she still loves it.

Love the Stretch
I have two 15 ish pound dogs that love to pull and tug on this toy...all day long, every day. It's long enough for the humans in the house to also grab an end and not worry about getting nipped by playful pups. The fact that it stretches seems to be even more fun for the dogs. We have several other similar unstuffed long toys but they get very little attention. This toy is definitely unique and a cut above the other similar toys. The stretch seems to make all of the difference. If they had more animal choices, I would buy them all.
