Whats up guys, ive been doing some searching and think i figured it out but want to make sure. I have a Tial 40mm wastegate with a 15 psi spring. However, I need something in the area of 7-8 psi. tgh99si has a small green spring from a 38mm gate he's willing to sell me. So this spring will work for me and put me right at 7.25psi correct? TIA, josh

 

Yea the small green spring will put you at 7.25psi.

 

awesome thanks you sir. And this would probably be my best choice for 8-9 psi low boost and 13-14 psi high boost right? (EBC)

 

Anytime buddy.

 

do you know if tial 38mm springs will fit perfectly in a tial 35mm? i have a regular tial 35mm

 

Yea all Tial gates use the same springs. The spring rate just varies from wastegate to wastegate.
