Fresh ideas anyone? I have no boost

i have an sr20, sidemount with oe pipes. stock turbo replica (ebay like in quality).

atm i get 0 boost. in neutral, under load, in the driveway or on the highway, nothing. i hear no blow off. i feel no boost. my car feels like a kia now.

It wasn't always like this, she drove fine all last week. Monday night i got on the 826 home and i had boost then. about a mile before my exit i hear a loud burping noise. i stomp the gas and no boost. slow acceleration. i figure its loose intercooler piping.

i limp home and open the hood. i check all the pipes, nothing is loose. spray soapy water everywhere. no bubbles. check all the vacuum lines, all tight. i don't have a vacuum gauge, just a boost gauge but everything is tight. there is no visible smoke coming out of my exhaust, well nothing significant indicating water or oil burning/evaporating.

also, the engine idles kinda high around 1k rpm. it doesn't surge, but a warm up of 1200 rpm down to 1k isn't normal either. it wasn't doing that before.


so basically, i want to know if ya'll think its simply a blown turbo? what could cause a turbo not to work at all? last time i blew a turbo, i still got some boost and a smoke screen. also, what could cause my high idle? i know how to adjust it but it wasn't a problem before, and i don't want to adjust the iac if theres a problem elsewhere...

any help would be appreciated

I blew the bearing in my 2871 top mount set-up, and thats exactly how it felt. I was cruisin around the high line of the bank at OSW, and about half way through the corner the car just fell off the bank and straightened up. Did a pull down the back straight, and it built 1 psi when it should have built 20+psi. Turbo was straight done for.
 
bad turbo

and you didn't get smoke out of your exhaust right? is it likely that that would happen on a journal bearing turbo also?
