99 STI V

Hi,

My STI 5 has all of a sudden started whineing at 2500rpm upwards.

I am presuming its the Turbo?

It used to slightly whistle (audiable due to de-cat d/p), but now its whineing, its loud enough to hear inside the car / outside the car, still boosting fine tho.

Should I be worried?

Maybe turbo bearings gone?

any ideas?

Have you got a prodrive backbox fitted? If the baffles go they sound like a jet engine!

Sounds like you have a roller bearing vf turbo,some of the later sti were fitted with these

Mine does it too. Previous owner said it has always done it. Its not worrying me. Sounds quite nice

Nothing to worry about then?

Funny really, had a loud exhaust (hiper) on before so it masked any noises, put the standard exhaust on and now hearing all different noises and getting scared

Yes it is a VF turbo (VF28) on STI 5's I believe...

Yep, its amazing the difference with a quiet exhaust. I really prefer the quiet one now, and its heathier to get used to hearing the engine / turbo noises.
