Thoughts on a 6.0 Turbo?

So seems there is alot of luck with throwing a turbo on a 5.3 and making big numbers! Why not go with a 6.0 and have more displacement and power out the box? I already have a 5.3 and some 6.0 heads to lower compression but reading different things about it being a slug bad before boost. I was planning on picking up another motor this one I have now is for mockup mainly. So any reason not to do a 6.0 so I have more pep out of boost and more potential in boost? Anyone know the stock compression on the 6.0? Figured I could get away with 10-12psi on it. E85 is very easy to get around here and planned on setting it up for that, also it is going to be a twin turbo car.
Thanks

6.0 is just fine too. Just cheaper and easier to get the small bore, small piston, thick cylinder wall 5.3 to live as it gets cranked up. Dont do the 6.0 heads on a 5.3 on E85, ever. Ive had them both and its the torque difference is barely noticeable as long as the turbo is sized correctly to not have monster lag.

No reason not to boost a 6.0L just 5.3's are more plentiful, and a lot cheaper like said above. The 6.0L will make more power out of boost, and more power at lower boost, but max HP is still dictated by the factory rods which are the same in both engines.
I want to just put this quote in my sig in hopes of people reading it more so as to not as the question all the time.

So 6.0 with a good set of rods and pistons? Have good power before boost and monster power in boost? Anyone tried a built 6.0? Would it be worth the expense? This car has already gone out of control as far as over the top build so another 1k to do a 6.0 really wouldn't matter. I am a shop owner so labor cost is just my time only parts are the expense.

With stock stuff like mentioned before it isnt the cubes that really matter they all make the same power before they blow. You are only going to make the power based on 2 things... how much air the turbo will flow, and at what level will the engine hold together.
Keep the factory compression, dont lower it. A stock 6.0 I had ran on gasoline with 15psi and never had issues....its doable.
My current 6.0 has aftermarket rods/pistons. I run it a bit harder than the stock setup though. Was it worth to build? I guess if you exceed the limits of the stock setup and still want the thing to hold up.... Yes it was worth it.

Out of boost you are not going to see a huge difference between a 6.0 and 5.3, I didnt. Then again I never pulled a trailer with either and didnt build them to be optimal out of boost.

I know its hard to detect on the internet, but have you ever heard of sarcasm?
Your hardly thinking outside the box with a 6.0. Now if that 6.0 had a 4.8 crank, L92 heads, was compound charged, in a baja 54 beetle. Now that would be "outside" the box. Good luck with your combo.

I had this same thought... have the 5.3 but i also have a 5.7 ls1... didnt know which would be better but since im new to the ls game i figure i would go with whats proven and enjoy the car for alittle. So i went with turbo 5.3. I am happy to hear that the difference between the 6.0 and 5.3 with or without boost isnt too huge. Now im more confident in doing the 5.3.
Btw i LOLed at the sarcasm thing.

The 6.0L LQ4 or LQ9 block bored .030" over for 370 inches is a damn fine all around turbo motor. Great rods, Great pistons and the stock crank with a good tune will live with 15psi and what ever horsepower your budget and driving skill warrant.
Yup true but you add displacement and boost well.......you know the drill.
fwiw i have a 6.0 in my yukon and it has a ton of power for being as huge as it is. Made me realize holy **** this will be fast in something 2000lbs lighter and with a S480 turbo
as ive been told Do it Once. no need to go smaller and say damn i wish i went with the 6.0 its really not much more expensive once you get into it, Anytime you turbo it will never be a budget build
