12V primary turbo advice please

I've suddenly found some motivation to spend time on the truck.



I'm looking for primary turbo advice, as to what turbo to run with my 63/68/12 for daily driving and towing.. Thinking a simple S475?



All mods in my signature should be up to date, and if they are not, I will change them right now.



Truck has 4.10 gears and is soon to have a ZF6 transmission...



Thanks in advance

Bob
