Boost issue

Ok guys I'm having a problem. I have a 89 nissan 240sx with a stock series 2 rb25det. All stocks parts. Now here is the problem I have 0 bar during the car running idle, and under a load Im not getting any boost and the car has no power. Any suggestions?

mayor boost leaks or blown turbo, maybe open stuck wastegate, blown ic pipe, it could be a lot of things man, what have you checked?
Does the turbo even spins?

Maybe the wastegate arm just popped up haha - good chance of this.

Yeah!, but what would that say about the TS?
Give the car a twice over and also check the boost gauge's vacuum/boost connections, ECU codes, Then check timing.

You should have around MINUS 0.7bar at idle, meaning your gauge is either unplugged or not working

This. Verify flapper swings freely and arm is connected. Then report back.
