hey everyone,

i am putting my own turbo kit together and the manifold i have is made for a 44mm wastegate. i was wondering what spring should i get with the tial wastegate? also do u think the stock bov will hold 23 or 24 psi on my 35r? or should i buy the aps twin bov?

 

which spring?

 

what boost controller?

 

i have the greddy profec spec b 2

 

the 11psi spring is typically the norm for 44mm wg's but you can go with something else more suitable for your build

 

well i will only be runnin 23 to 25 psi on my 35r. what happens if it is the wrong spring?

 

inconsistant boost if the spring is less than half the boost you are trying to run

if you are going to go to 25psi i wouldn't get anything under a 13psi spring

 

alright thanks!

 

If you don't want to rely on your boost controller get a heavier spring. The heavier the spring is the less the boost controller has to work.

 

thanks. i just brought one with a 13 psi spring and see how that goes.
