a couple days ago i was asking about a ihi vf39 turbo from a suby, well i bought it. real cheap. only 10k on it. the factory wastegate actuator is set at 14 psi, now, can i use an actuator from a different turbo like a 14b or 15g, if so what are these set at. i would like to run about 7 or 8 psi to start out with. and i don't mind making a bracket for the new actuator. i just don't know wich is a good one to purchase. any help would be great. thank you
