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

eh if i were you i would look for a wastegate from another IHI turbo from a junkyard. Not sure off the top of my head what cars they came on, but most are set anywhere from 5-8psi.

or use a blockoff plate and attach an aftermarket wastegate on manifold

14b or 15g, if so what are these set at

i think with the factory internal wastegate setting on the 14b is about 8psi.

if i were you, id weld the flapper shut and convert to external gate

pretty cheap really, since knockoff WGs only run about $60

what kind of mani are you using? Some ppl have welded external w/g flanges onto the HF mani; but just remember that it IS cast... If you could get up pics of how the stock internal w/g is mounted, someone might be able to help you find another internal that would work... 14b is set at 8 psi, but i'm not sure how easily you'll be able to mount it...

How small is that turbo? because 14psi on that would be different than 14psi on a larger turbo...
