Hey all i had topic running on stange turbo noise before.

Taken my turbo out which has only been in since recondition for two drives. Found major shaft play, so much so that it's hitting both sides of the turbo with the fan. Looks like the bearing on the compressor side has gone.

NOT HAPPY!!!!!!!!!!!!!!

how the f$#K can this happen after newly reconditioned?

Checked OIL and WATER and all where working perfectly.

Can this happen via impact, from postage?

Has this happen to anybody else?

Had you done any modifications to turbo?

There is no way i can get this on warranty since they came from hongkong so i need options. Where can i get another cartrage, core for turbo? GT2530 are not made anymore but does Garrett suppy these still?

appreciate any advice.

If anybody wants me to put up sound recording of broken shaft in engine just say.

:(

it was probably balanced incorrectly or not at all

it MUST be balanced to sustain correctly alignment at 100,000rpm+++

speak to GCG in sydney for a quote to rebalance a hks turbo

its probably going to be a lot, as its quiet extensive work on their vsr balancer and you may need new internals if they are shagged

reco'd by a coffee grinder?

yep hence the no return!

Well i can attempt to return but trouble + time - money saved = not worth it.

So my problem still remains, i want to just get my project on the road. How to fix, properly reco, can the bearings be replaced?

www.gcg.com.au as per pm

Thanks Paul i took the turbo there today, also to garrett. They took the turbo appart and found that the bearing had broken and there had been heaps of heat thought the turbo. Funny for two drives under two km. So not sure if it's because it was a fake reconditioned turbo (from Hongkong) or that there was a small coolent leak on the line running to turbos that didn't amount to much. Leak may have caused a air pocket not letting coolent though enough. There was coolent and oil going into the turbos. Weather it was enought i don't know.

Anybody know how to check cooling into turbos?

:rofl:

HKS definately do still make and sell GT2530s for GTR.

I rang BD4's and you can buy GT2530s again but only in twos for GTR's and 300z. No spare parts though. HKS wasn't making them for a year, but started again.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
