Downsides of intake port and duct mod?

It is time for a rebuild of my 1987 930 and I'm looking at increasing the intake ports and duct to 36mm. Are there any downsides to doing this? My reading of this subject on this site gives no negatives, but I want to make sure. I have found many comments about the cost of this modification. If you have had this done, I'm curious what you paid.
