I was wondering if i can control the boost on a 14b with one of the boost controllers that go on a vaccum line?? Or is that only for external wastegate??

 

you can run one on a internally wg turbo, jsut put it on its vacum line

 

So i can up the boost with just that?? I don't need to change the Wastegate actuator rod or use a spring??

 

a bigger (stronger) spring does the same thing, your just changeing the amount of pressure it take to open the gate.

 

What about a turbo with a internal wastegate? i am new to the turbo thing.

 

the waste gate (internal) is basically a large spring with a thin peice of rubber over it (a seal). then the pressure on the seal gets high enough to colapse the spring, it opens the waste gate, lowering the pressure, which then lets the spring rebound, closing the waste gate.
