G'day all,

I drive a 93 R33 GTS-t and recently I have noticed a high pitch 'whistle' coming from the engine bay upon acceleration. I'm pretty sure its not the usual turbo spool and i'm just wondering what it could be and if it's normal??

Secondly, my drivetrain seems a bit noisy, again, im not sure if that is just a normal thing with a sports car as i've previously only driven family/luxury sedans which would have more sound proofing. I'm thinking its the gearbox because when the clutch is in, the noise goes away, however the gearbox feels pretty good.

Just wondering if anyone can give me some suggestions?? Thanks. :P

I can help with the gearbox noise, if it is noisey with your foot off the clutch in neutral and quiet with the clutch in it is caused by a worn thrust bearing. Just replace it when you next do the clutch.

The rest is hard to guess without hearing....do you have a pod filter? they can whistle sometimes as can a turbo

Heap it seems to do it mainly when its cold (not the engine, the ambient temp), and my car is 100% stock (as far as i know) so its not a pod or anything, although it sounds intake related (obviously). I'm going to get it serviced pretty soon, so i might ask them to keep an ear out...

As for driveline, symptoms are exactly as you describe, thanks for the help on that one.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
