Vacuum stuck at 9in.

I have a cheap 200 dollar t3/t4 turbo with a sr20det, synapse recirculating bov, synapse wastgate, car was running great now all of a sudden i have no boost and the gauge is stuck on 9in vacuum. Car runs okay and idles fine.

blown turbo. same thing happened on an old t25 i had.. my vaccum was like 12, instead of 26, seals around the compressor housing had gone bad.

So im kind of seeing the same thing with my CA. pulling about 10-11 when it was about 20. would a blown turbo make it miss.

So update on what was wrong. My vacuum went down to 9 but i noticed it was still boosting about 5psi instead of 8psi. So i thought for sure it was a vacuum leak somewhere well come to find out the bolts from the two connections from my exhaust manifold to my wastegate came loose and burned up the gaskets. Also all five of my dumpipe bolts were vibrated loose by a half inch.

Fix all new studs with all metal locking nuts and retightening them after a 15min break in period.

Boost and vacuum all good now .
