(1999 – 2013) Chevy & GMC Silverado / Sierra 1500 / 2500 Truck T6 Single Turbo System

$3,999.00 $3,799.00

On 3 Performance is proud to announce the release of the 1999 – 2013 Chevy / GMC 1500 & 2500 4.8, 5.3, 6.0l single turbo system in the coming months. Our turbo system is a bolt on design that has a very clean and simple install. This kit is based off of our T4 kit that we have offered for a decade, this will use the same kit with a few upgrades to allow you to run our T6 80 and 86mm Billet Wheel Turbos.

We designed the kit to use the stock driverside manifold. From there we made a crossover which is included in the kit ( will clear 4×4 parts and transfer case ) to bring us to the passenger side which is where we located the turbo. Each of the kits come standard with the On 3 Performance 80mm CNC Billet Wheel Turbocharger, with an option to upgrade to our 86mm Billet wheel as well.

We have a completely custom turbo manifold unlike any others currently on the market which is completely divided from bank to bank. Its not the typical log manifold that most make and run the driver side bank into. We have both banks completely separated up to the turbo flange which makes for a very cool looking and functional header. With the T6 turbo moving more air, we opted for dual 44mm wastegates. One in the standard location on the manifold and a second one underneath in the crossover. So we have great positioning right at the flange and right after the first bend in the crossover to keep good control over the boost. Included with each turbo system is two of the On 3 Performance 44mm v-banded wastegates which is loaded with a 7psi spring.

To expel all the exhaust from the turbo, we designed a 4.0″ downpipe from 304 stainless steel. This is all constructed from thick, 16 gauge wall tubing which has been proven to stand up to the abuse. This will come with a downpipe only and then a 4″ vband flange and clamp for you to build from.

The complete cold side of our turbo system is designed using 3″, all aluminum tubing to help dissipate heat, keep the iats as cool as possible and reduce weight. All the tubing is bead rolled to keep the couplers tight when in boost and prevent popping couplers. Not only that, we included stainless t-bolt clamps which provide more clamping power than your traditional worm clamps some use. All of our custom On 3 Performance couplers are 5 ply and come standard as well with each kit. Lastly, our intercooler is the same proven unit we have used for over 5 years with the other turbo systems we make. Included is the 4″ core unit which is good up to around 1000hp.

WHAT DO I NEED TO FINISH OFF THE BUILD QUESTION:   This question is asked daily, please read through and understand what you are doing and what your goal is. With our T6 turbo system, we suspect youre going to be after 700+hp numbers. This is a typical build that we see and this would be the items used in a 700+rwhp build.  In order to support those numbers, youre going to need fuel system upgrades. So below I have listed our dual pump assembly upgrade and our injector options.

Need Help Choosing The Proper Turbo?

If you do not know what you are doing with turbo sizing, not sure if you should go with the T4 or T6. please call in for advice.

New as of 2017:  We now have a 2nd Gen manifold that we created to be more durable through the abuse these trucks see.  This is a very unique manifold design to start with and as you can see we opened an investment mould.  The main runner area is a 3mm thick seamless stainless casting to be as strong as possible.  Highly Recommended Upgrade:
