  • No boost ?

    Heey guys ,
    Got a question , fitted my boost gauge & BOV yesterday got vacuum from manifold . Gauge goes to 0 max ( no boost ) & BOV don't blow off throttle .
    The turbo light on dash never come on when driving , (since I bought the car few months ago ) .
    Are the light suppose come on when turbo is on ?
    Turbo blown ? ( been driving NA all this time ?) lol
    Cheers !

    is it a 1g or 7m?

    take your air filter off and rev the engine. you should hear the turbo.
    and by the sounds of it, yes your turbo sounds like its screwed.
    also if its a 7m try taking the intake off the turbo and seeing if it spins or not.

        Did you tap the boost gauge and the blow off valve into the right place to receive a positive boost signal, or merely into a port that provides vacuum only?

          You should still hear a 'pshhh' noise when you change gear, even without a BOV. I took the BOV off my 1ggte z20 and it still made a loud pshh, and the new jzz20 does the same without a bov (probs has factory bov though but still).

            I tap it off the inlet manifold where the 4 vacuum lines , I used the spare one.
            Any suggestion ?

              That's manual
              Being auto it shouldnt sneeze until you back off of the throttle while on boost
              Bov or boostleak

              Even when a turbos blown it still will make boost

              I'd remove the Bov and test again

                  Found out turbo she's no good, no spin .
                  Took the intake off , tried to spin the turbine but seize up .
                  Lucky I bought couple from Daniel (1GGTA70 )

                  Thanks to all for the suggestion ! You all Good Man !!! lol
