Yeah, I still have A/C and PS.

As I said before, the compressor side of the turbo on the Greddy kit is facing away from the PS and A/C components, so you can keep it. Some manifold and turbo combinations face the other way and interfere with the PS and A/C, so they must be removed.

If I cared enough, I would remove A/C all together but it isn't worth my time and it kind of helps on those scalding summer days.
