Re: Turbo question... Noises?

["Winggee" <winggee@hotmail.com>]

Alrighty!.. I finally got a recording of the noises. rename the extension to
mp3. wav was too big.

i'm willing to get as dirty as i can to resolve this.. hehe.. aren't we all
mechanics here.

i have acquired another turbo, though only the center cartridge will fit.
but i don't wanna change it if i don't have to.. though right now. the car
still has some boost but there is a problem. as a friend who has the exact
same turbo, doesn't make a hint of that whistling noise. it's almost like
the turbo is surging. or something..

Thanks!!
Wing
