Ticking Noise On Boost

[rawd]

Hey folks

Just recently started noticing a ticking sound around 5-6psi that seems to be coming from the engine/turbo. Only happens on boost and used to be intermittent but now i am starting to notice it a lot more (maybe cos now I am listening for it all the time). From suggestions in other threads I have:

Changed plugs - NGK bkr6es w/ 0.8mm gap

Changed fuel filter

Turned down boost

Cleaned AFM

But still happens.

Car is an rb20 w/:

front mount

x-force turbo back

hybrid ebc

everything else is stock

I have heard engine knock before, and I'm pretty sure it's not knocking cos the sound I am getting is not so gnarly. It's more like the wheel of fortune wheel sound as it gets spun. I know it's pretty hard to diagnose a problem without seeing the car, so I'm more looking for recommendations on what it could be and what else I can try to fix it. Already taken it to a few mech's and they don't really seem to know or want to help.

Help.

Thanks.

Sorry, also ran a bottle of fuel injector cleaner and did not help.

is it really noticeable or does it sound internal of the motor, if its the latter it could be pinging.

PS you must be taking it to the wrong mechanics!

Not heaps noticeable. Got a panel filter with stock box, so the car is pretty quiet.

If it's pinging, is there anything else I can do to stop it?

Read that some EBC solenoids will make a ticking noise, but would it consistently do it at 6psi?

Might try returning back to stock boost soon and see if it fixes it.
