I changed out the turbo on my 85 GN. ever since than, the turbo psi gauge didn't work... i've checked the hoses, fuse, and other things... i can't find the problem!! I have no clue what kinda of boost i'm running, and thats kinda important. Please, if anyone has any experiance w/hooking up the turbo boost gauge... help me out!
The stock gauge isnt much good but, there is a T right below the the intake inlet hole. off that T one vac line runs fpr? and the other vaccum line runs to the right side of the car behind the the heater boxto a map sensor on the right fender well. Check your vac lines first That T is plastic and breakes easely.
good luck
