garychoffmann Posted June 14, 2010 Report Share Posted June 14, 2010 I'm going to assume that you modified the manifold to fit the turbo. By regulator are you meaning wastegate? How does the car run? Need a little more info. Could be a boost leak, bad seal at the turbo, clogged cat. Many different thengs Link to comment Share on other sites More sharing options...

Funky Phil Posted June 15, 2010 Report Share Posted June 15, 2010 You may need to pull the turbo off and inspect the wastegate flapper. Make sure it is closed at idle. What exhaust do you have?? I assume aftermarket downpipe?????Is this from an 3sgte(twinscroll) or a 7mgte??? Link to comment Share on other sites More sharing options...

TainterRacing Posted June 16, 2010 Report Share Posted June 16, 2010 you wont need much fuel with that turboJust cause it appears bigger dont make it better. I think you got it right there thats' a smaller turbo then the 12a. The turbine is smaller and so is the intake wheel. That boost might be all the turbo can do on the 2.6l Link to comment Share on other sites More sharing options...

That boost might be all the turbo can do on the 2.6lBut I fell that with this turbo spool at hight 4000rpm + and with the 12a spool better at low rpm.Ah an other think my VACUM is -10, this is a boost leak?.

Funky Phil Posted June 17, 2010 Report Share Posted June 17, 2010 The late spool is because that turbo is a dinosaur Link to comment Share on other sites More sharing options...
