It's really whatever you want for base pressure likely 14lb would be good for that turbo to get a baseline 93 tune.

the spring should be green,blue, black?.

Depends on what year your wg is from it appears, but green + blue + black looks correct if your gate is made after 1/16/2012

If it came with some springs just bench test it and look at tials chart.

Are you worried about vibration of the blue fitting/filter on the oil return? Looks a little long.

If anyone has info on which valve spring works with stock Valvetrain let me know. I've heard of the Crower 65lbs springs with gm retainers. Not sure if it actually works.
