Turbine Housing Removel

[ELB Racing]

I am looking for some advice here on how I can, SAFELY without damaging my T3 turbine housing, remove this bastard. I have searched, but with no results on removal if its stuck. I have removed it before about 2 years ago when I got it all Jet Coated and the Compressor housing ceramic coated.

It seems to be stuck from heat/cold, it will not budge. The compressor will move, just not this. I have tried PB Blaster and WD 40 just to try it with no luck. I need to rotate it and its kicking my ass. Some of you work on them for a living, some may have had it happen. Running out of physical ways, got tricks of the trade guys?

Well I just got it using a piece of 2x4 and umm "lightly" bashing it.  I'll leave this thread open just in case anyone comes up with better ideas in the future.
