Turbo's been making metal to metal sounds since about feb or march or so. Still been running about 10 psi normally...13 or so occasionally. Everything has been pretty much ok since the turbo started acting up...only other things besides the noise were that my mani to turbo gasket blew out competely, and my turbo didn't spool til about 4 grand or so.....here's the prob....

I was driving home from work yesterday on the highway and all a sudden the car started boggin and stuttering, felt exactly like it does when i blow an intercooler pipe off or have a big boost leak. The car continued to drive for a short period stuttering and whatnot, but it got worse and worse until finally it shut off on the highway. I pulled over and checked for intercooler leak but found nothing. I even tightened my bov spring and reset the computer just to see if it made any diff. Still wouldn't idle and wouldn't rev. Well I had to get it towed home which took about half hour to 45 minutes or so. Well soon as the tow truck leaves I try to start it up to try and trouble shoot...well starts up with no prob and idles fine. I turned it off and let it sit over nite cuz I didn't have time to mess with it.

Well I went out there tonite and started it up again....yet again it runs fine. So i decided to take it out for a spin. I stayed close to my house just in case. I drove around for about 15 minutes boosting on and off ( to rule out a boost leak) and the car ran fine. I got it parked in my driveway and let it run for a few minutes. Not 5 minutes after I got home with it, it starts sputtering and bogging and finally cuts off.Won't idle straight after that. I smelt fuel while I was trying to keep it running so I'm pretty sure it's not a ecu protocall or anything where the comp is trying to shut down. From what I can tell, I don't believe I'm getting any air after driving for a lil while and the engine being warm. Is it possible that the t25 finally just locks up now after it heats up preventing air from entering the TB? That's the only thing I can think of rite now...either that or maybe a faulty component in the TB or AAC. That still wouldn't explain why it won't rev tho. Plain out feels like i'm not getting air tho. My temp guage doesn't work rite now either....would the SR do this if it was overheating? Please tell me it's just the T25 cuz I have a new turbo sitting in my room. lol. Perhaps maybe the mani to turbo gasket doing this? I dunno...I need to find out tho before I install 5grand worth of parts on it. ANY info or ideas would be much appreciated, thank you.
