Hi,

Below is a link with 2 video uploads of the problem.

I drove 350km for a cruise and now started to have this problem. It's making a squealing noise like a pig on high rpm.

Car is 1999 Nissan Skyline R34 GTT at 114500 km

RB25DET

Stock Turbo

Stock Side Mount Intercooler

HKS Bov (its not the bov, i used to have Blitz Bov, didnt fix)

Any ideas on what it could be? Will be taking to my mechanic next week, but If it's an easy replace/fix, I could do it myself and save some money! any help is appreciated.. thanks

Probably turbo farked

Boost leak or possibly turbo bearing. ide check for boost leaking first.

Just watched the video, yup, sounds like a boost leak.

Check you cooler pipes are tight

Maybe leak from the compressor intake (split joint?).

SOLVED

Squealing pig noise gone !

Thanks for the responses. If anyone else having this problem, apparantly it was the turbo gasket bolts. They were loose!
