If you do have a aftermarket LSD, most likely a clutch type just buy the correct oil for it and it wont be as noticeable. Either cusco/motul.

Im thinking it does have a clutch type LSD. However when just turning around a corner say at 60kms 3rd gear. it will still click. is this normal?

Yes it does have an aftermarket LSD, NOT OEM.
Whats the best OIL to chuck in it?? ill go drop and chuck some new one now if thats the case.

Called up mod project and they know the history of the car and suspect its gearbox LSD related and not the driveshafts. So back to square one, have to rip apart the gearbox to inspect.
