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???

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.

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.

:D

Thanks

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?

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

      High temp brake fluid?

      By Komdotkom · Posted

      Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup. I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!

      Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!

      Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!

      HKS Vcam Step Pro Issues

      By believer · Posted

      I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.
