r33 RB25 whining

Hey guys,

Recently bought an r33, pretty standard beside a FMIC, exhaust and a pod filter., but it is making this weird whining/metal sort of noise whenever you accelerate. I cant get a good video of it but i found someone who managed to, but dont visit the forum anymore so i cant ask them what it was!

Video is here

First turbo/import ive ever owned and my knowledge is pretty small when it comes to cars, and for the life of me i cant figure out what the sound is. Car still drives fine, boosts fine (no gauge yet but should be arriving tomorrow) but the noise is really annoying and can be heard over the engine while driving.

Any ideas? cheers

Wait.  Is the noise independent of you twirling the steering wheel?

Nothing to do with the steering, its pretty much purely when i accelerate, and gets louder the more i give it.

Could be sitting in neutral hands out the window revving the car and it happens. 

Probably timing belt since that gets whiney and noisy if: 1- the belt is a gates racing or similar. 2 - is too tight. 3 - probably both. Take off the top timing belt cover (after you carefully remove the CAS) and tell us what you see. I'm guessing a blue belt.

Pull ancillary belts one at a time. I'm putting money on power steering pump or alternator bearing.

Remember: Fan belt also drives water pump so don't run the car too long with this one off

thanks guys ill have a look hopefully tomorrow, ran into another issue gotta fix that first.

was driving, then all of a sudden lost all power, and car starts hopping. pretty much undriveable and just jumps every few seconds in bursts. it idles and revs alright in neutral, and also does reverse fine, but as soon as i use the accelerator it just hops around. thinking coils misfiring or TPS?

ok so didnt fix the new issue and seems to be worse now. Car turns over and starts, then pretty much instantly stalls, if i manage to start it, it doesnt want to rev past 2500, at first though it was coils/spark plugs but didnt fix it, then found the 2500 limit, so im thinking air sensor.

Cleaned out the maf, didnt do anything, let the car idle while i packed up and stalled, and still wouldnt go past 2500. going to try a new one and hopefully that fixes it otherwise im stumped.

    • Yeah and hence my ghetto way of slamming the brakes, get the ABS to cycle, rebleed seems to be a sensible workaround.
    • Hey! Happy to help. Nothing inherently wrong with the adapter, it's more so with Brett Collins himself. He gave me a lot of incorrect information when I was in contact with him and was extremely rude when I challenged him. He stated I could not use any aftermarket twin plate clutches except for his own, not to use the dush shield, bla bla bla and it was all BS.  Collins stated to cut roughly 14mm's off the housing, I took off 15mm to make room for the dust shield. I would confirm with whatever adapter manufacturer you're using. 
    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go.
