On3 turbo kit

[14 gmcl83]

has anyone used the on3 turbo kit 76mm kit on a stock truck? How

hard is it to install any issues ? I was thinking down the road maybe turbo my

truck or go get a zx1000-1400 bike for speed or a used gtr in a few years once truck is paid off .

I know everything about them ask away. 

I had a smaller turbo now I have the largest available 76/75 bmf gen2 billet. 

Race intercooler 

Larger springs open exhaust. 

Stock little over 550rwhp.

With supporting fuel 850 is the record but it has meth also.

Thanks sir so how

long was the install and what hp do you need to worrie about fuel system ? And is the kit a true bolt on a kit ?

You can check build thread. But it is bolt on. The race core intercooler was 3 days worth of grinding the denalingrill but other than that yeas bolt on. You still need
Tune
Spark plugs
3bar map
Boostcontroler
Exhaust.
550 or a little more at 12psi and it can go more I made over 600rwhp but that is not advisable this is on the 5.3l.
Lt4 injectors and pump are cheap but don't net much more. Low side fuel pump on top of all that and 700-800+ are all doable with a good tune. Meaning you can go less power say 700 and e85 stay in safe fuel.levels and make great power.
Power is easy on these motors issue is trans and torque management. It's a tune all in itself.but I would be happy to send you a free tune or 3.

1slow1500,

I am looking to do the same setup. Can you send me your tunes?  I want to do some compare vs. the stock tune.

Hi welcome to the forum. Unfortunately some people here have discouraged 1SLOW1500 from participating in the forums, so he is no longer here to help with turbo questions. You will have better luck on Performance Trucks .net or LS1tech getting the help you need with tuning. 

[flyingfool]

you can still review all of slow1500's post he posted lots of gems of knowlege left behind before leaving, its too bad we have so many smeagle's up in this mofo

75 turbo might be a bit large for the fuel system  , i guess you won't be going full tilt on it.  i'm still studying the whole boost set up and getting parts..  LS1 tech is a good source, while Perftruck .net is a bit slow on activity lately and lots of disinformation on there..

Yeah I hear you on that and I appreciate your reply it seems like people get mad when other people try to explain something. And if they're right they would rather just get rid of the people that know more than they do. I tuned it about 4 different times I actually am making progress it's just on the gen-5 GM's there is so many tuning tables that open up but I also have HP tuners Believe it or not SCT derive advantage 3software actually offers more tables and part meters for tuning

If you buy the On3 kit, ditch the oil evacuation pump and tap into the oil pan (just below the rail) or the timing cover for a gravity drain (-10AN size, no smaller). The pump is unreliable. This prevents it from being a complete "bolt-on" but do you want easy or do you want reliable? 

[Batemanbry]

Thinking about buying one of these kits for my 15 Sierra to help pull my toy hauler. Just curious how this affects fuel milage in regular driving. The price of fuel these days is ridiculous.

Would this fit a 2015 Chevy 2500 6.0?

[pokismoki]

yeah the 2500's with  6.0 motors are the best platforms to tune on.  go for it, pull the f***'n trigger!  check the build section on here you might find some other ideas
