You can use the same manifold and turbo as I have and keep the A/C, but you'd have to use a different adaptor plate. The compressor housing would be twisted torward the front of the car more ( meaning that you'd have to get a half-sized radiator ) and the Down-piping would have less room and be closer to the block.

I've seen it done by a guy on H-T/HMT. I think he was making 189whp on like 8psi with PS and A/C on a Y7/Y8 and starion FMIC.
I can't quite remember his screen name, but it was something like "sctty" somthing..

I gutted the WORKING A/C outta my car before it was ever close to being turbo'd, so the fitment issues are something I have no clue about...
