Twins cost twice as much money as a single and make no real difference as a single for under about 1000hp.
Your best bet is to buy a single kit and set it up for around 7 psi and learn from there. Even a kit is still just the basics to get you going, you will still need a lot of other things, odds and ends to complete the build, not to mention, fuel system, tuning, tranny, ect. You have a lot of education to gain still.
As far as size, start with a 70mm on a 5.3 and work from there. Should spool well and make around 500 when you start turning it up off 7psi. I'm building a mild setup with a BW S366 turbo on a 5.3, it's a little smaller, but with a bigger turbine so will make 5-550ish.

See where I live there is no one around who tunes things. And yes I do have a lot of learning to do with this turbo stuff never have tried it before I've built motors to make kinda big power but I just really don't wanna go into the motor or my 5.3

I'm thinkin of going with a 72mm turbo, so can I use my stock injectors still? Or do I need bigger injectors or bigger( extra ) fuel pump? I'd love to run twins tho if I could but that would require me to dig into the motor tho wouldn't it?

check out my build threads. I have a bone stock 5.3 with trick stage 2 kit and make 500 wheel hp.
I have proven this is the perfect setup for stock motors and for people that want decent power without losing drive-ability. Over 60k miles of boosted power and the kit has been flawless since the day I installed it.

See I didn't kno if the motor would handle boost the way it sits now or not? I was hoping I could get by with not the cheapest of kits but not the most expensive either. My truck is 4wd with 35s and I'm looking to gain more power since its lifted. I'd love to turbo it but I'm clueless about them. I'd like to go twin turbo but for that I'm sure I'd need to get into the motor ( which I'm trying to stay out of) is there anyway I can get a it with a turbo and not have to change heads or the cam an stuff?
in my opinion, you can add single or twin turbos without changing anything. Just upgrade your fuel system and add meth. I have a 05 GMC Yukon Denali with a whipple 2.3 pushing almost 20 psi. Only thing I added was fuel system and meth. You’ll have to keep your boost low, maybe no more than 5 psi and drive it sensibly.
