Strange Noise M35 Arx

[180JDM]

bloody hell mate, they liked your cash!

[Jetwreck]

just to close this off.

The noise was happening around the 4k rpm in almost any gear at half throttle.

it's the turbo!

it's the turbo!

hmm

thats starting to sound like a possibility... wish i bought that warranty now...

its so wierd that it groans and resonates when under load and half throttle but under full throttle it kinda goes past it too fast to make the noise.

Thats what ball bearings do when they fail.

I have to listen for that bearing noise all day at work, bloody bearings. Thats half the reason I went for a bushed core for the rebuilt turbo.

I doubt you'd like the warranty.. used car warrantys are a crock of shit really..

my friend had to replace his gearbox on his 180sx.. i could have got him one installed for around 600 including a reco box..

he ended up having to pay about the same.. on top of his warranty (which only covered a small amount). and couldnt get it done at a place he wanted..

As for my noise.. i am sure its only the ac.. seems to be fine with it off.. i am up to the 100,000 tho..

[wailiam]

I tried AC off and it still does it

I tend to agree with Jetwreck here Wil. Sorry mate.

Better start saving up ~$2k for a GCG highflow (or a little more for a GT-RS) so the money is there when you need it!

Dunno if you are aware, but the OE turbo's were a factory replacement item at 100,000kms or earlier.

Pretty ridiculous I know, but that is what Nissan elected to do. Why they would not use a different design is beyond me.

in NSW by law they have to supply 3 months warranty with the car. im not sure if thats only if its registered. but check it out before you go buying a new turbo!

its so weird this problem just 'happened', it was perfect to drive!!

I'll check it out...not sure if the warranty is statewide. is a bit of a shame you didnt pick it up but its not that easy to replicate the noise so I totally understand. I doubt it will die any time soon but it's an annoying noise!

It's at Nissan right now, dont think they'll be able to figure it out...

Hmm High flow... Will a CGC high flow spool up earlier or later than the standard turbo?

I dont want it any laggier than stock.

Will it also mean I need to get it tuned so + $ for emanage or some other computer?

[zei20l]

yeah look into it mate!

have a search around the stagea forum for people that have done this mod. i dont think youll find its laggier, if you do, it wont be by much

and no you can happily run it with the factory ECU. unless you want to start upping the boost and doing some mods, then a copgyback or a remap is probably worthwhile!

Guys, I'm now experiencing this same problem and after reading this entire thread, seems like a few have experienced this issue but no has seem to pin point the cause? I've done fairly low Ks on mine, about 70,000 so I'm surprised that the turbo has let go already...

Any other feedback?

Cheers

check everything made from - or attached to - rubber.

and the turbo

and the front drive shaft

and the tailshaft and mid mounted bearing

also wheel bearings

that should do it
