Turbo failure?? please help me
Recently, i am losing boost,gauge shows very low boost about 2-4psi over 4k rpm, I am unsure why. my car starts to lag at about 4k rpm on every gear and then something like back fires with noise and shake. I think that I can hear the turbo is trying to spin but it hesitates (I don't have a BOV installed). when not using the turbo (low rev), car runs smooth as.
any idea, please help, thanks very much. |

BOV's come stock, so did you take yours off?

Re: Turbo failure?? please help me
Are you getting any Check Engine Lights?
Did your turbo suddenly get louder or start whinning? Have you pressure tested your intake for leaks?

Re: Turbo failure?? please help me
im assuming you have a vr4/stealth TT...not a tt conversion? any mods?
sounds like your turbos shot, but normally thats associated with a whine or a screetch. maybe you have a damaged vein? definitely pressure test though |

Re: Turbo failure?? please help me
How do you not have a BOV...every vr4 came stock with one. LOL. Pressure test, I have a feeling that is where the problem lies.
