Just Installed R33 Turbo In Rb20det

[allthewaytotheskyline]

just installed a r33 turbo on my rb20det and there seems to be a whizzing sound on low spool.......

the turbo has no shaft play and spins freely without a sound out of the car....

there is no smoke or anything of that sort....

any1 have an idea of why it would be whizzing when spooling up???

im kinda scared to drive it...a mate told me that it may not be getting oil....although my last turbo was fine and didnt whizz...and got oil just fine...all i did was place the new turbo in my old turbo's existing place....PLZ HELP!!!

does your r33 turbo on ur rb20det make a whizzing sound???

[Equinox]

Installed one on my friend's old RB20 and yes, the exact same noise! Was so loud it was scary.

Asked on here but no one seemed to know. The turbo ended up working fine for the whole time he had the car.

[mystery_kid]

uh

as far as i know, my car has a stock rb20 turbo and it makes this exact wizzing sound you're taking about

sounds like it might have a rb25 turbo then.

nothing to be worried about, all works fine

[TTT]

come on man..

you gotta do better than "whizzing sound" with todays technology.

video then youtube, then link to here.

hey bud. might be unrelated.. my R33 25t.. i get a whizzing sound too.. my turbo is stock, no shaft play, oil etc so thats normal. ppl on the streets hear my turbo spooling up haha. kinda cool at times.. but i try to keep a low profile.

[allthewaytotheskyline]

it literally is a whizzing noise...not spooling noise....im scared to drive the car...ive relpaced over 10 turbo's and neva heard a turbo sound like this....

on low spool it literally sounds like a whizzzz whizzzz whizzzz....

[R32Big_boy]

If you have a MASSIVE screwdriver, put it onto the center of the turbo and put your ear on it. You will be able to hear the bearings inside. If they seem to be spinning fine then its probably nothing. However if you can hear somethings wrong with the bearings then yeah its not getting oil or one of the blades is off balance.

will try that now...any1 else got an idea???

Hey

I just installed an r33 turbo on my rb20 and the spool up does sound different to what the rb20 turbo did.

mine has a whizzing sound on low revs.....

[nismobdykit]

I am looking to do this.

What type of wizzing sound? Video, Audio?

I am very interested.

[allthewaytotheskyline]

ummm i will try and get video tomorrow...literally sounds like this....whizzzzz whizzzz....not your regular spooling sound...

[r32toy]

I have the same noise to but it stops and comes back.. does yours always do it??

[bad_rb20]

ive got a r33 turboon my rb20, and yeah had a high flowed r32 turb before, a mate also has a r33 turbo on a rb20 but the r33 turbo's in general seem to make alot of noise when spooling up.. its got a big whistling/whizzing noise as it spools up..

Dont worry about it,

If your worried and can be bothered, then take it to the mechanic and get him to check it out, but i highly doubt there's anything wrong with it.. my mechanic said all r33 stock turbos seem to have a real whistle to them.

Thanks

does it reverberate through the exhuast system at all?

[boostdef]

If you have a small leak at the connection to the intercooler piping, you will can a rustling leaves type sound. Also if the dump pipe has not been connected properly.

I had my turbo spool to 12psi once in my r33, and it did sound a hell of a lot different to the 7psi spool up (obviously).

What boost you running?

[WazR32GTSt]

what actuator did you use?

is the wastegate fully closed when the car is at idle?

[allthewaytotheskyline]

wow thanks for the reply fella'z....its got the 10psi actuator and yeh the whizzing is always der on low spool and once it spools up it goes away and is quite a loud noticable spool....

although i gotta admit its definately an upgrade and very noticably gains throughout the higher rpm's.....drifting is much nicer now....and quick shifting to second leaves your wheels spinning....

its a funky sound the whizz...and quite sensitive to spool up...i checked all connections and there all tight with no leaks.....

ive inspected it very closely and seems ok...drives fine...im going to get my safc tuned and up the boost to 14.5 psi and see how it goes...wish me luck!\

I WILL KEEP EVERY1 UPDATED...IF ANY1 HAS AN IDEA ABOUT MY WHIZZING PLEASE POST...YOUV'E ALL BEEN GREAT HELP!

sorry to sound like a total noob but i thought stock R33 GTST turbos can only be pushed to 12-13psi max???

i may be wrong

[allthewaytotheskyline]

ive been advised by my tuner that on a good tune it can handle 14.5psi
