Na its the same.

The reasons for mounting the turbo is because.

Talking in RHD cars.

The compressor is on the passenger side if you have got rid of AC. This way the down pipe has better access directly to the recess of the sump. Sure theres not much room for a filter, but this is the usual way if you don't have AC.

The compressor is on the driver side if you want to retain AC. This way the down pipe can just fit in between turbo and the AC compressor. The exhaust pipe then has to squiggle down to the recess under the sump. The turbo flange on this option is angled out a bit so the compressor housing does not clash with the block webbing. You may have to shave some. If you have a larger turbo it will clash with the engine stamp block. This is the problem I had.

My car is set up retaining the AC as initially I was going to keep it, but since got rid of it.
