WGA spring upgrade


I saw the actuator spring upgrade on 03.10.2005: Saab NG900 Wastegate Actuator Spring -
And, since I have a spare one with weak spring, I plan to rebuild it.
I cannot find this Nordic spring which is used on platonoff site, but I found forge ones. There are green, yellow, red and blue, rated 5-10, 9-15, 17.5-20, 14-18PSI. Can these be put inside stock T25 WGA?
If so, which one is safe for stage 1, 2 & 3? Stock spring inside actuator is green, as seen on platonoff site, but is this color marking the same as from forge ones?
