I did my research and it's called 'compressor surge'
the pressure that builds up from the turbo cannot enter the engine when the throttle is released, so the compressed air has nowhere else to go and exits from the INTAKE turbine of the turbo which can be very harmful for the turbo and/or engine.
It sure does sound good but one of the way to fix it is putting a bypass or blowoff valve, so the pressure exits the wastegate when the throttle is released.
@razioth I have a GT4094 turbo on my FD and it has two BOVs, still get that sound. If I just rev it at a standstill you can see the BOVs both fluctuating back and forth with each surge of pressure. Also if you have a larger wastegate dump like mine(50mm), you hear weird noises from it too :)
there r two types of surge sound in turbo setup . one is compressor surge , the other one is flutter noise . this is more like a flutter noise . notice that the air sound / noise still get pushed out . meaning there is a slight tone in it . if its a total compressor surge , the it would be so obvious that its like air / wind being push out unnaturally . sorri not good at explaining . but try searching some vid on flutter n surge on youtube . u usually get flutter if big turbo or 2 bov .
@TheMagicalBikeCrew yeah man in 10 years time people will be pulling that kit off going previous owner was a tosser for installing this rubbish on such a beautiful shape car. How do I know? Take a look at all the Datsun 240z's with shitty kits of them now. ;-)

The VeilSide Fortune kit never did it for me, it looks great, but it doesn't keep that traditional FD styling that I've fallen in love with.
