On 3 Performance is proud to announce the release of the 2002 – 2006 Chevy / GMC 1500 & 2500 4.8, 5.3, 6.0l single turbo system. This kit has been in development since early 2013 and is now on the shelf, ready to ship. Our turbo system is a bolt on design that has a very clean and simple install. Now that we have been shipping for quite some time, we have gotten a lot of great feedback from customers. One of our favorite quotes from a customer was when they stated, This thing makes so much torque my truck would pull my camper straight up a tree. Once the turbo system is installed and setup, the drivability doesnt even change. We have daily driven our shop truck for the past year to prove this. If anything it actually improves as the turbo is very responsive and the 70mm is quick to make boost. So with lightly accelerating, you will find yourself not pressing the gas pedal as hard with the better throttle response. This is also due to the new found power your truck will be making mid-range as well
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 70mm turbocharger and we have options to go anywhere from the 70mm to our newest 78mm.
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 truck engine bay being so open, we a good amount of room to work with for the wastegate as well. So we have great positioning right at the t4 flange to keep good control over the boost. Included with each turbo system is the On 3 Performance 44mm v-banded wastegate which is loaded with a 6-7psi spring.
To expel all the exhaust from the turbo, we designed a 3 to 3.5 stepped downpipe from 304 stainless steel. This is all constructed from thick, almost 3mm wall tubing which has been proven to stand up to the abuse.
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 3 core unit which is good up to around 800hp and you can always upgrade to our 4 core if you do plan on pushing the truck to the limits.
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.
