hey guys just wondering if my turbo is about o give or i have an exhaust leak . well here goes when i drive and run around the 2500-3k rpm , i dont feel as much boost . the turbo gauge never seems to go to the plus area . always down to the negative 7 - 5 area , does this mean my turbo needs a replace or maybe i should check the exahust manifolds to check for leaks ? any information would be nice .

sorry took soo long to reply , well ya i checked the vaccum pressure and its steady at 20 hg at idle ? plumbing seems to be good , when i dont start the car the boost gauge stays at 0 but when i start it the meter drops to the negative part . im guessin its my turbo , so im going to be looking around for one

The turbo should only make boost with load. Therefore at idle or steady cruise, you'll read vacuum. Stomp the throttle at somewhere above like 2700rpm (With the car in gear and driving of course, you'll get nothing in nuetral) and you should get boost. If not then either the gauge is goobered or something else is wrong.My beloved Z:1987 2+2 NA2T w/30a swap.
