When turning my car off i can hear the turbo spinning down to a stop. (like on the big bb turbo's)..sound goes on for a fair few seconds

the reason i ask is a friend of mine also has a highflow turbo but his does not do this.....maybe his is not bb??

anyone else have this?

cheers ...Jim

One of you had a pod and the other doesnt?

Generally thats a good reason. If you have a airbox or enclosed pod the sound is not very audible.

If thats not the case, your friend probably doesnt have a Ball Bearing turbo.

No great drama... Nothing to be alarmed about :P

ALL R32 - R34 turbos are Ball Bearing. 100%

The noise is not to worry about, mine makes it. I love it!

But it has often got me thinking that noise means things are touching each other.....

What are my wheels touching, or it it simply the sound of the bearings turning which is then amplified/resonated by the compressor/turbine wheels?

BASS OUT

i have a plain bearing hiflow turbo

i have the standard airbox,

only thing i can hear is my walbro fuel pump, when turning off my car.

But when my turbo is windin up, it sounds like a truck turbo.

hasnt blown up yet, sitting on 12 psi, and comes on pretty strong .

Had my hi-flow for 2 years at 1 bar with standard air box and k& n panel. Never had any noises after turn off.Oh,......there was that time the engine fell on the ground,but that was more of a clunk than a turbo whine.

well, I have a Garrett GT30 with a 4 inch intake, through a 90mm AFM to a big motherf**ker assed pod.

Anyone want to hear it spool? :D

Also, takes about 30 seconds to nearly a minute to completely spin down with that metalic noise after the engine has been turned off.

    • KYBs are typically twin tube, putting them in the lower tier of desireability. Do you just want to replace worn out ones for the lowest cost? I mean, you wouldn't just replace one end of a car, if the rears are a similar age to the fronts, then they are probably nowhere near what they should be, and likely won't be great against brand new fronts. So, to spend ~$800 on 2nd tier dampers, when you could get a decent set of MCA coilovers for <$4k.....? As to the strut tops. 1st up, the Sparesbox site specifically tells you that they are not correct for an R33. Beyond that, why do you think you need them?
    • That's not very Toyota of the Toyota!
    • Bringing an old thread back to life Looking to put some new front shocks in the r33Gtst and the KYB still look ok for a road car. Unless there are any other options aroind that price $200 a shock?  I’d like to replace the strut tops also, is this the correct KYB no. For the strut top, KSM7124?  https://www.sparesbox.com.au/products/kyb-strut-top-mount-ksm7124?srsltid=AfmBOoq-HDru8wSlLnQrhU9gCw_uYdKg8gUQzONY-EQOdnI5iXOWEUjY 341287 appears to be the front KYB shocks part no.  thanks all
