ive been tring for like 20 min.. is there some special trick? how do you hold the shaft from spinning?

 

Might be reverse-threaded :gay:

 

Yeah should be reverse threaded. Don't reef on it too hard, if you bend that shaft you're focked. Best way to take it off is with a two handled driver, like a tap holder and extension with socket, with the turbine wheel nub clamped in a vice.

 

You don't say what kind of turbo it is.

However, since I think all turbo's are the same when it comes to this:
You've gotta have two sockets... one on the nut (compressor side), and one on the shaft (turbine side)... and it's reverse threaded.

Are you doing a rebuild? If it's a T25, here:

and make sure the threading is correct, a lot are reseverse threading.
