see, im not sure, and im damn hoping its not the gearbox, as its only around 30,000kms old and its a r34GTT item, recently did the oil with blue redline gear when i did the clutch..
the noise only seems to come on after a quick thrash, it sounds like when the clutch fan hits the intercooler piping, if anyone has heard that noise befor..
It only comes on when the clutch grabs and you dont allerate, if you hit the gas the noise goes away, but say youre slowing down and just pop it into gear and let that slow you down the noise will come and stay untill you press the clutch, or hit the gas..
if you get what i mean..
