SR20DET vacuum problem

[New2SR20]

I searched and did not really find any problems like im having...my vacuum reading on my boost gauge when the car is idling is @ -2. I did not get another gauge to get a alternate reading but i will tomorrow morning..Still it bugs me..and the turbo is fairly loud at idle...sounds like a waste gate flutter. Anyone have any vacuum problems like this? The idle is set @ 900 but it changes from 850 to 900 due to the large cams.

You'll see a slight decrease in vac due to the cams, but nothing that should account for that much. Have you done a check to make sure you don't have any vac leaks anywhere? Given the turbo noise, I would recommend pulling the intake plumbing to check for shaft play just to be on the safe side

Thanx..Il be doing a check today..I found a vacuum diagram for the SR and I will def. check the turbo for shaft play even though the car has not been driven since the build and the turbo was fine before it..still..you never know..If anyone has any other ideas feel free to post
