Are you going to be pulling in a particular class? Or is it run what you brung? Also what is your end horsepower goal? But as for turbos I would look into a danville 2.5 turbo, garrett stage 1 3794AVNT, or a garrett stage 2 4094 AVNT. Alot of it depends on what power goal and injectors you are planning on going with.
And you can run all three of these turbos with stock injectors and cp3 if you have efi live tuning. As far as injectors go I would into going 30-40% over injectors and a Fass Titanium 150 or a Airdog DF-165 for and lift pump and you will be golden.

30% overs are roughly 100-115 and 40% overs are roughly 140-150. The 40 percent overs even though they are larger would be a better route to go because they will help lower drive pressure because you don't need as aggressive of tuning to help spool the turbo. I would honestly shoot for the 600 range because that will help maintain reliability with stock internals. And that setup should tow great as well with a some other mods like watermeth or a intercooler!

Fass 150GPH is what size of lift pump you will need. And the tataniums are not adjustable but you dont need to change the pressure on these trucks. And with a intercooler, watermeth, efi, exhaust and downpipe, egr delete, and a built trans the truck will run great! That will be a great pulling/tow/ drag racing rig. You will also want to upgrade the front end with some HD tie rods and support kits
