Correct me if I'm wrong this is just a theory. I can see more load being put on a turbo out playing in the sand with paddle tires so shouldn't he be able to get away with a bigger unit? More load on the motor the faster the turbo spools right?

There is quite a load in the sand. In the dirt the power I have does well and it's respectable onthe street. When I bolted 35" paddles on it became a turd. I'm not super concerned with spool time but I don't want to wait till tomorrow either. I was thinking bigger to be in the eficenty curve of the turbo as much as possible. But I under stand you can go too big. Im just confused as to why the numbers I come up with tell me to go so big.
I'd run somewhere around an 80+ mm on it. Run big everything for room to grow. Big crossover, wastegate, down pipe. Pm if u have any questions. Good luck with the build.

The best advice I have ever heard:... Only take B( . Y . )ST advice from someone that is CURRENTLY running a turbo setup close to, or bigger than what you want......
rpm range wil lstill be the same reguardless of size of turbo. if he staying from 1500-5500 then a smaller turbo with a larger AR will suit well. give him the powerband that he needs.Originally Posted by Frenchy
as for size of crossover and etc, look into thermal dynamatics on how sizing hot size plays huge role in spooling a turbo

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
I did some work for the guy that owns turbo hoses (the company that makes all the high end silicon hoses). I went by his shop and was going over what I was doing. He recommended the GT3582R and to go with the 1.06AR over the .82AR. he is giving me a bunch of stainless bends (2.5") for the hot side, and some misc. flanges he had laying around. So I guess Im going stainless. He said that turbo would leave me room to grow, as boost is a drug and you will always want more.
Also on a side note, aside from the turbo does everything else on my list seem properly sized or adequate?
I have read through this theater and even though there are some good answers here. You all forgot the main thing you need to do a Turbo and that is money money and more money lol
