On 3 Performance is proud to announce the release of the 1999 – 2001 & 2007 – 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. 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 84mm.
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(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.

Need Help Choosing The Proper Turbo?
If you do not know what you are doing with turbo sizing, please call in for advice. We do not want to see you ruin your turbo from lack of proper understanding about motor cubic inch size and turbo exhaust wheel sizing. We most commonly see this when our customers try to put a 65 exhaust wheel on a 6.0 or larger motor. The rule of thumb is the larger the motor, the larger the exhaust wheel you are going to need. If you put too small of a turbo on too large of a motor, the turbo will fail due to this. Again, if you have questions, please call. We can’t possibly know what your project/swap is if you order the kit off of the website without reaching out to us first. Generally, a 70/65 or 76/65 turbo will be just fine for a fairly stock 4.8L or a 5.3L motor, but not ok when you step up into a 6.0. The 6.0L and 6.2L motors should have a 78/75 or larger turbo, depending on the build. Understand that the 76/75 BMF is fine as well, and will actually generate more power than the 78/75. If you are building a 408 or larger, we recommend going with an 88/84mm turbo or a T6, depending on what you are trying to accomplish.
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:
What kind of horsepower and torque gains are you getting from the single 70mm and the 76mm turbo kit. Also can this kit be installed on a stock 5.3l without harm to the motor with adding boost.
There are too many variables to answer that with bolt ons, engine details, etc. Anything from 400+ depending on boost, tune, fuel, and the list goes on. Right now our shop test truck is a stock 5.3 long block, around 13-14psi and making 610/670
When you will arive an turbo kit for gmc sierra 5.3 2014-2016
We need that think please
I would say our single system will be out late fall. Its in the works right now as we speak, we are designing on a shop 2015 GMC 1500 that we purchased recently
The gmc sierra 2015 will be arived in 2016 or no
Will you be making a twin turbo kit for the 2007-2013 model? Also what size injectors would you recommend going with on this with the fuel pump addition?
We plan to mock up the 07-13 TT truck design this winter
Will it work on 2wd or 4wd
We designed on a 2008 4wd so your good with either 2wd / 4wd truck
So do you not have a kit ready for an 07 2500 6.0
Yes we keep that system on the shelf and always in stock
Do you have any plans for the 2015 6.0L vortec?
We just finished the design stage of the 2014+ 1500 turbo system. Hoping to release before the end of this year
Wouldn’t this kit fit the 2015 1500 since there almost the same exact design ??
No we are currently designing a specific kit for the 2014+ trucks. They are different and the heads are clearly different on the direction injection engines
I wondering how much will be the single turbo kit for a 2014 Sierra 5.3 Crew Cab ?
That kit is currently in the design and testing phase. Its going to hit the market right around $2000 and go from there
So are these available for the 2007-13 5.3 or no?
They are in stock and ship daily

I have a 2011 gmc sierra 1500 with a 4.8 ltr how much hp and torque will I get with you single turbo kit ?
Depends what you can support, our kit has the potential to take you from 400 wheel to say 900 wheel with the appropriate supporting mods
Got a 2105 Chevy 5.3 want a turbo when will it be out ? Only one I’ve seen out for new trucks is the Armageddon twin turbo. Which starts at 6K.
It will be released this winter
Interested in the kit, however I have some questions. Does the stock kit that is pictured, come with EVEYTHING needed other than fueling options?
It comes exactly as stated, there are multiple other items you would need if your starting from scratch such as fueling and tune support.
Would this kit fit a 2500hd vortec 6.0L
For sure, 4.8 / 5.3 / 6.0 engines all have the same head flanges
i am thinking of buying this for my 2008 5.3 1500 sierra 4×4 crew cab. what all other upgrades will be needed for the truck to be able to handle handle the power, and will there be room in the engine bay?
We have a list in with each kit outlining all the optional items that we can supply with the kit. Its a proven system we have sold for years, it all fits in the engine bay as you can see in our photos

What is the bare minimum supporting mods to safely achieve 500-550hp? Does the factory flex fuel system suffice or will I need to upgrade to a larger injector? I’m trying to do a budget build. And so far this is the best kit for the money out there. Looks very sound. Just wish there were more pictures/videos and info of after the install. Would love to speak with someone direct if possible.
There are quite a few videos and photos posted, if you need to speak to someone we have the phone lines open Mon – friday 10am to 5pm. Give us a call
Does this kit adapt well to 2007+ GM Suv’s? Interested in a kit for my 2007 Tahoe
I have guys that run the kits on the suv applications however I personally have not done the install. Most guys have just commented they made their own intercooler mounting brackets as that was required. They have them on the trucks so I know it will work. Just wish I personally had hands on experience with those specific applications so I could be more detailed for you

I’m really interested in this setup.
I have an 07 GMC Sierra with the 4.8L. Not trying to go too radical. Is it possible to install on stock injectors and stock fuel pump?? If so what hp range would I be looking at??
In most cases no, we can add a 2nd waste gate and allow you to control it down to 3-4psi only. At that level, its possible you can get away without injectors but I don’t think you will get away without upgrading the fuel pump at least. Its just not worth it, fueling is the key to a good tune
The kit for the 07-13 does it need anything besides fuel and tuning
Primarily yes that is it and we are working on a base file to allow customers to get a start up tune from us. We should be offering that around the first part of the year. There are a few other options that we have in the optional items area you might check out. We can make it as complete as you would like.

is this kit custome made to my 08 silverdo 1500
Yes its a bolt on system for your 08
James Leanza –
Would you recommend any tranny upgrades with the increase in power? (08 2500 6.0)
We really swap anything thats making decent power to the 80e. The 60e is really the weak link

Bought the single turbo kit for my 2013 Silverado regular cab. I installed the kit myself. It was pretty easy to do. With the stock transmission it made 480rwhp on a completely stock 4.8 motor. Then I swapped over to a built 4l80e with a loose 3600 stall converter. I then ran the 4840 pound truck at the 480 horsepower level and it went 12.1 on back to back passes. We then turned the boost up to 18lbs and we were able to make 622rwhp on a bone stock 4.8 with the 76mm turbo upgrade. I’m taking it back to the track in a couple days. Yes, it still has the stock cam. Hopefully it will run some mid to low 11’s.
Nice thanks for following up. Our shop truck on 625 wheel goes 11.30’s so you should be right there. Good luck and let us know how it does
Will this kit fit 08 2500hd 4×4. Sorry cant see anywhere specifying between 2wd or 4wd or if it fits both.
Yes its good with 2wd or 4wd
Tim B (verified owner) –
I did make it to the track. It ran 11.40@122 on back to back runs. I need some suspension work to get it to launch without blowing the tires off.

I’m very interested in this kit. What injectors would I need in an 08 5.3 with the upgraded fuel system
You would want to read the section in bold RED font that covers the options and exactly what you need. 55# injector option is the most common though to answer your question
When will the twin turbo kit be released
We are not releasing a 07-13 turbo system
Jarrod Paul –
What injector set should I get for a stock 2007 Silverado 2500HD 6.0L with the 70mm turbo kit & fuel system upgrade? Also, will it be emissions compliant? Is it a true bolt on plug-n-play or is a “tune” required with this system?
Depends on fuel but I would suggest just running our 80# kit so you can go e85 if you want. Thats pretty much all we run in our builds
Is this a true bolt on kit other than upgrading fuel and tuning the truck is everything bolt on
This is a bolt on system that we have sold for years now. You can see the optional items in the list which you can select to finish off your build.
