Hey zzp. I was wondering what wastegate spring comes in the stage 2 turbo kit for the 2.4 cobalt. I have the mvs style 38mm wastegate. I recently built my motor and want to shoot for 20 psi. Should I just get copper, maroon and brown to make 20.30 psi which is 1.4 bar?
Thanks in advance,
Jarrod

 

Just put a manual boost controller on it.

 

i have one but I thought you can't go over twice what the wastegate spring is rated for. and wastegate is more accurate...

 

There is a good chance it will want to spike too hard with a high spring. Just hook up a boost controller. I have a 13 psi spring and it doesn't have trouble hitting 29psi

 

I only had a 9 pound spring in mine and was able to hit 30.
