hello there..need help on my tial mv-r 44mm what spring rates is the best for bnr s5?.

 

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.

 

my springs color..
