hey guys, am looking to raise the boost on my stealth and am wondering what is the max boost pressure it can take, its got no mods, 100% stock only think i want to do to it is boost the pressure a little and maybee an axhaust!!

 

14psi

 

 

got a problem with tha 91 stealth rt tt, a vac line is off coming from the boost solenoid but idk where it goes its tha top one with tha white lines on it but it has a brass fitting in the end. and the car is making a knocking noise in the back head. doesnt really seem 2 phase it any tho. my friend has a 3000 gt that does the same thing only non turbo anyone have a clue? im thinking valve problem.

 

That vacuum line goes to the rear turbo intake pipe.

 

anyone have a schematic for the vacuum lines? just had the timing belt, water pump, crank sprocket and tensioners replaced and the did some of the vacume lines and not it seems like the boost just isn't working right. You can hear them boost up and watch the guage jump up but, the power just isn't there. One of the lines was routed in between the back heat shield and the O2 sensor and burnt right though it. It's the one that has some piece attached that has an adjustable dial on it and say out on one side. Any input would be a GREAT help.

Thanks,

Wayne
