Hey,

i have a r32 gtr with a r33 rb26 thats fully worked that was rebuilt no more then 20 thousand ks ago.

i was driving it home 2 days ago and just as i drove in my drive way it started making a ticking/knocking noise.

does this sound like a spun bearing??

if so what could have caused this so soon after a rebuild? i got it compression tested 2 weeks ago and came back perfect then this happens??

my race bred sounds like a tractor...

So.....who built it? What is done to it? Possibilities of failure are semi endless, incorrect assembly, incorrect clearances, losing oil pressure etc. Need to pull it down to have a look.

when u take the engine out, take off the head and throw the entire bottom end straight into the tip because pretty much none of it will be salvagable with that load a knocking

Sounds horribly like a spun bearing alright. Had one myself not long ago. I'm happy to come and have a listen close up just to confirm it if you like, I'm in coorparoo, but don't drive the thing over. Don't drive it at all. Send me a PM and I'll be happy to come and have a look.

Did you follow the run in procedure set by the mechanic?

Run in?

meh, bed it on the dyno, tune it up. If its put together right thats all it should need

Either way, its beyond dead. crank and everything no doubt to the recycling mill :P

and ye, endless possibilities as to what could have killed it. The list is long

      M35 Brake caliper replacement

      By Waders360 · Posted

      Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
