[andy95'R33GTR]

i here my turbo turning sound 1 to 2 sec. after i turn off the engine...what could this mean?help

[rockabilly]

that they probably have been replaced with 34gtr ones which are rolller bearing, hence the noise..quite normal.

how to check if i have roller bearings?

[SLYNE]

rip them out?

so this is normal hearing the turbo after turning the engine off, but i can only hear it when the place is very quiet

its normal for ball bearing turbos to keep spining when the engine is shut up

relax

but what if its a stock...not ball bearings???

[STR8E180]

how do u know that its stock?

eazy way to check is to remove the intake pipe and spin the compressor wheel with ur fingers

if it keeps on spining for a while its a ball bearing

yea ne turbo that keeps spinning for a few secs after u turn off the car will most probably be an upgraded turbo, u wont really hear it with a small turbo though, like str8e said take off the intake pipe and spin it, and check the shaft play up down in and out while u at it, if it is a small turbo making that noise it may be worn imo

ok thank you so much...i post pictures...il try to remove the intake today..ill keep posted

[andy95'R33GTR]

i already removed the intake..and the turbo is written GARRETT M24 A/R42

i tried turning the impeller and it stops at 2 to 3 seconds....what could this be stock? or ball bearings?? i just send the pictures later... i have a little oil deposits outside...and have a little clearance when i check for play of the shaft...

It could be a hi-flow turbo - I know hi-flows spin a few times after you turn off the car... actually quite normal... even if it's not an aftermarket turbo you run - I wouldn't worry... a turbo is like a fan, if you turn a fan off, it normally does some rpm's before coming to a full stop.

If you lose performance then I would worry, otherwise... not a major issue mate.

[andy95'R33GTR]

what about the turbo numbers?? is it stock?

[andy95'R33GTR]

hello? anybody?

My 33T does the same thing... BB turbs tend to keep spinning for a dew seconds after shutdown. If they didnt I would be more inclinded to worry.

google is your friend.
