Pulled up at my girlfriends tonight after a short drive from my house (like 5 mins). Had warmed the car up before the trip and was just pulling to a stop when i noticed a weird sound. Doesnt go away when the clutch is in. Oil pressure is normal (i think its what it normal is at at idle)

Anyway it sounds metallic, kinda a rattle. Like when the powerballs go around in their clear sphere when the lotto is on tv lol. Its definitely from the turbo side of the engine, around the turbo somewhere. It can be heard from in the cabin (much clear then with the bonnet up), and its also clearer with the bonnet down listening with your head near the guard (cuts out the fan noise)

I did a search but nothing seemed to match what im after.

Car is manual, GTT, 60 thou on the clock. Cat back and pod, stocko boost.

Anyone else had this problem?

Its inconsistent, as in doesnt have a set rattle, it goes and comes and is not repetitive.

Maybe turbo bearing? Hopefully not engine bearing?

You gotta listen kinda hard to hear it with the bonnet up and that goes for in the cabin aswell.

Any help would be great/Ideas to try and rule out

so have you tried it yet grant? i only ask cuz i have the similar sound ur having hi-pitched metallic sound but very hard to hear in the open and can only hear when in an en-closed area like a garage... but the headlights on would make it alittle louder than it is..

      After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
