Skyline R33 Gts-t 'squealing Noise'

[Mr_GaZZa]

hi every1,

i got a 1995 skyline GTS-T

150k - km's

its stock/ish everything.

stock boost

FMIC

HKS Superflower POD

thats it

today i got a new muffler / box on my existing 3 1/2 system.

i boot it up the road and i hear this squealing noise @ over 4000rpm?!

if i back off the throttle it stops?

any1 kn0w what it is?

thanks GaZ

Where's the noise sound like its coming from? could be anything but probably leaking gasket or poor weld, since you just got a new muffler put in.

[Mr_GaZZa]

Sorry the noise is from front left of the car 'so engine bay'.

still boosts fine

i am so puzzled, cause it was fine before that!

thanks guys

GaZ

NOTE just took her for a spin... can go all the way to 6000 rpm off boost no noise! i fink it could be related to no back pressure ... there fore overspools ???

OK, well had guy take my car out! the noise is just the spooling of the turbo.. just a louder hissing noise. not a leak!

Just to be safe i'd recommend checking the exhaust studs, had similiar problem with mine and had it checked by three places all said was turbo bout a week later got lot worse found one exhaust stud snapped off and two more about to go, was at less k's than yours also..

If it's squeeling sounds like a turbo gasket on exhaust side

[Mr_GaZZa]

OHHH MY GOD!!!

i was driving home from work today, had music loud... i was at lights @ the front of the line so i turn down my musix, lights go green i gun it up the hill n the squealling noise is WORSE!!!

Figure out the problem?

Turns out it was my stock SII Turbo. A piece of turbine wheel came off unbalancing the shaft and rooting the bearings . Good thing i had a GCG R34 Highflow waiting to go on. All fixed now, and more powah and more noise . Must remember highflow with no supporting mods is a not good (for the wallet) .

cheers
