Car seemed to run fine up until a week ago or so. Then it felt sluggish and I could tell it wasn't boosting. No I don't have a gauge but you can tell when these things are boosting. I built a boost leak checker and found two leaks. A loose waste gate line and a crack in the hard elbow in the diverter-turbo line. Fixed those and the system held pressure so I took her for a ride. Still nothing - same sluggish heap. I kept doing 2nd and 3rd gear pulls with no success until on one pull the turbo suddenly kicked in -- but only for a second and when some noise and then both it and the boost stopped. I was able to do this one more time with similiar results and then after that nothing. NO BOOST.

I'm going to go and get a gauge tonight as well as look for another leak but I am afraid the problem is with my turbo.

Any help?

Could be a failed n75 or even the wastegate acuator, bench test the n75

How do you bench test the N75 or wastegate?
