Noisy VF23 turbo

[WRXONP]

hey fellas..

i got a VF23 a while back to replace my blowen VF22 and ever since i got the VF23 its had bearing noise??

when engine is idling u can hear the turbo spinning....and when u turn the engine off u can hear it winding down to a stop...

i was wondering if this is sooooo bad ..the reason i asked is iv had a lot of RBs with standard ballbearing turbos and they sound the same??? have they all been rooted??

my question is does this urgently need rebuilding?? has been doing it since i got it??

and can anything on the vf23 bee modified to make it any better?? sounds stupid i know but i did read on one members car a while back a modified vf23?? dont know what got modified LOL

what sort of price am i looking at for a rebuild??

or should i go td05h 20g?

Good question I was going to ask the same

A mate bought a v5 recently and it's doing the same

Seems to boost fine but can hear the turbo slightly whine at idle etc

Can hear it rev up if u gas the car a bit at idle but after 2krpm can't hear lol

Maybe masks by engine noise

[WRXONP]

yea bro same...which turbo is his???

seems common as iv seen heaps of vf23s for sale stating the same...

and my old skyline did the same for ages without blowing...

the noise on mine goes away as soon as u start making + pressure as the noise stops and u hear the suction "spool sound"

Both the vf22 and 23 are ball bearing turbos and bearing noise is normal on idle or low rpm and when switching it off for 5-10 seconds. Its only a problem if its screaming its tits off on boost. Some will be worse than others, I enjoy listening to the sound of them when there spinning down, they sound farkn Orsum! ;D

I had a VF22 that did the same thing for a few months before it blew itself to peices under boost

[Ninja8)]

my vf28(ball bearing) had whining noises from the day i bought it till the day i sold it (1 year) and it was still strong.

[WRXONP]

oh funny...so allgood??

its not passing oil so that must be good

thanks for the replys fellas

Yea i was wondering the same thing too.. my BG & BH both have VF22s and they both sound like you describe but boost hard as

[Stoffa]

did you check the shaft for play before you installed it?

just fell for play, it should have minimal play if you push and pull on the nut on the compressor wheel, but should have no play if you wiggle it side to side.

If its not smoking and theres no excess play it's probably fine.

I noticed a noise increase once I removed most of the recrictions on the intake with my Vf28 (140,000kms on it and it still went fine)

[WRXONP]

yea mine has no play what so ever and isnt passing oil at all....bu does the sound...but i have a full exhaust and full aftermarket intake if that would make the turbo sound any louder on idle????

yeah my vf23 is noisy. especially so on its twisted setup. i stripped it down before installing and all good, tight as a nun's nasty too.

LOL i feel mint about it now...sounds like a jet engine spooling down when turned off hahaha

[sultan]

or pulling up to a fast food drivethrough window. that + a little bit of compressor surge and the person in the window really does think a 747 is collecting a big mac

Did ur one whine at idle or At revs

The v5 one is vf22 I think as not checked but on trademe auction the seller had put as turbo replaced with that so must be lol

[Guest]

my vf 23 does same thing bro.i couldnt really hear it before when i had my factory downpipe on,but since changing it you can here the turbo,

mine still spins for like 10 secounds after you turn it off,sounds awsome.and whn changing thru gears you can hear the turbo

never had any issues with it,ithink its just what they do,

[Pappu1]

The vf22 I just put On mine does that now but not for as long after shut off say 5 seconds and can hear it just At idle and maybe like at up to 1200 rpm

Seems to boost fine

I did put a de catted pipe on it so perhaps that's a factor lol

My vf30 never mde any whine noise whatso ever even with 3in exhaust and pod

[Stoffa]

maybe cos its just a thrust bearing not a ball bearing

yea i agree the vf30 is thrust and the vf22 is ballbearing...

my mate had a td04l on a wrx and made no noise like the BB VFs seem to do

[boon]

My VF34 and my friend's VF23 both whine at idle-low revs and when you turn it off. Personally I love the sound, it's almost like a little supercharger hiding in there somewhere.

It's just a BB center thing.

[WRXONP]

yea i allways thought ballbearing turbos would do this...as my old bb skyline turbos did the same thing for ages...

allthough wen i hit up steve murch on SDU and said that u can tell a BB turbo apart from a thrust bearing by the sound he said i was on crack basicly LOL and a fight started from there...

seems i was right though?

[Stoffa]

no steve is always right!!

but everyone on here has just said their ballbearing makes noise and their thrusts dont?

[sultan]

one in new mint condition probably doesn't
