I have a T3 42/48 turbo off a stock car, 4 bolt DP, and the wastegate is not the type with a nut and rod to screw adjust. It just has a spring in it... I dont know the spring rate though...and I assume a tial spring wont work....

Is there anyway to adjust this...or keep the boost down if the spring is say like 10-11 psi spring. I'm looking to run around 6-8 psi. Here's the best pic of it I got right now....just let me know if anyone, has any clue about these or actually has one. Thanks.

 

bump..

 

So there is just a spring behind the flapper door?

 

I'll have to get a better picture, but it looks like a tial....its like a bee hive with vacuum line off it, with a big spring in it.

 

anyone?

 

anyone know?

 

You cannot adjust the psi lower than what the spring is.

 

Ok I figured that, but is there a way to get a lower psi spring for a stock wastegate if that one is set to high?
