Description
On 3 Performance is proud to announce the release of the 1999 - 2013 Chevy / GMC SUV 4.8, 5.3, 6.0l single turbo system in the coming months. This utilizes the hot-side from our proven 1500, 2500 truck kit, accompanied by our new SUV cold-side and intercooler since the grille area is much different on the SUV's. Our turbo system is a bolt on design that has a very clean and simple install. Once the turbo system is installed and setup, the drivability doesn't 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 newfound power your truck will be making mid-range as well. We designed the kit to use the stock driver side manifold. From there we made a crossover which is included in the kit (will clear 4x4 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 84mm. We have a completely custom turbo manifold unlike any others currently on the market which is completely divided from bank to bank. It's 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(vented to atmosphere). 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, 16 gauge 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.
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. Your truck most likely isn't going crack 250rwhp. With our turbo system, you mostly likely going to increase power 80-100% minimum in most cases. Most trucks we put together will make 450-600+ depending on supporting mods and fuel. This is a typical build that we see and this would be the items used in a 500rwhp build. In order to support those numbers, here is a list of what we recommend adding to your purchase. This is a recommendation to eliminate the emails asking what else is needed. After you finish your install, all truck need a tune:
Fueling Questions: Please read, we get endless messages on what needs upgraded to support the power. NO the stock FUEL PUMP OR INJECTORS are going to support your newly turbocharged truck. Most trucks bone stock end up making 400rwhp or more at 6-7psi depending on the combo with a 70mm On 3 turbo that comes with the kit. That is about a 57% increase in power and GM did not engineer your truck to be making those numbers on the stock fuel system. The engine platform is strong and you can normally run it up to 600rwhp or more with the correct fuel upgrades and tuning. Our shop truck is a daily driven vehicle and makes 625/675 and the engine is bone stock from pan to intake manifold. �If you plan to boost your truck, you need to do the fuel system properly so you don't end up costing yourself more down the road by blowing up your vehicle. On any build we do, we run the dual pump assembly and the return fuel line upgrade. This is going to support 900-1000hp depending on fuel being used and several other variables. Its perfect from a basic 400rwhp combo to a purpose built race truck making serious power.
For the guys wanting to make as close to or over the 1,000hp mark, we suggest nothing other than the T6 kit we offer. https://www.on3performance.com/shop/1999-2013-chevy-gmc-silverado-sierra-1500-2500-truck-t6-single-turbo-system/ Please review the following 2 items and seriously consider them when making your purchase for a hassle free, proven product to handle your fuel supply needs: https://www.on3performance.com/shop/on-3-performance-twin-320lph-universal-fuel-pump-assembly/ https://www.on3performance.com/shop/on-3-performance-2000-2013-gm-gmc-1500-2500-return-fuel-system-upgrade/
