Default VF52 Compressor housing swap

The skinny, bolt broke off in my stock compressor housing, was graciously given a blown VF52 to do a compressor housing swap.

The problem, I have taken all bolts off salvage turbo and and can't get the compressor wheel out of the housing, or the housing off. Haven't tried to force anything hard because I don't want to damage it so I came here.

Any advice on how to separate would be greatly appreciated!

What bolt where exactly? The most common bolt that breaks is the one that bolts the TMIC to the compressor outlet on the turbo. Very common. If this is the case, then an easy solution is to drill out the bolt stuck in the turbo, then use a nut and bolt to secure the TMIC.

The housing is sealed with RTV where it contacts the CHRA, AFAIK. You'll need to do a little bit of prying to get in undone. Note, I have never done this myself. Maybe someone who has can chime in to verify.

Uhh the rotating assembly is balanced and that turbo spins at 100,000 rpm. Bad idea to just take it apart.
