I have checked the FSM for answers to this question, but haven't found anything as of yet. Does anyone have an idea what the vacuum specifications are for a 1984 z31 turbo?

 

I'm going to make this simple. We can't get give you a good answer if you don't give us a good plain question. What do you mean by vacuum specifications? how much vacuum is it supposed to be pulling at idle? how much boost it's supposed to be running?

 

check your post on zcar.com it is answered there.

 

Thanks Roger! I got that this morning.
