what psi spring for tial bov/wg?
 

I have a tial 38mm wg and a knock off tial 50mm bov. How do i determine what spring to use? should the waste gate and bov have matching psi springs? I plan on using a EBC.

Bov should prob have a light spring. Experiment with the sprig until it barely stays shut at idle

Wastegate should have a 19psi spring.

I'm with this guy.

has anyone had any experience with these kncok off tials? any issues? I searched and found like one post which i think was done by tial showing failure.

few people on here use them.
no ill reports that I saw aside from having to fiddle with different springs to figure out what you need since they come with useless springs.

obviously tial is going to make them seem like completely worthless pos' cause they're stealing their business

well i just pull it out of the package and started to dry fit it together and the banjo bolt will only go int he vacuum port 1 thread! so i just sent a email to the seller. other then the thread it feels like a nice piece. I may just have to use a tap to clean the threads but its probably npt?
