I'm wanting to remove the Rats nest from my 1985 gs. I want to simplify the bay before doing any mods is there any way to do that and still retain a fully functional A/C system?

 

95...... GS?

assuming you're talking about an FD.... if so then the rats nest has nothing to do with the AC. They're 2 separate systems

 

however if its a 1985 GS, then there is an A/C idle up valve on the vacuum rack, which you would want to keep.
the easy way is to just leave the thing alone, its doing things you want, and taking it out is work.

 

i meant 85

 

I am looking to have a pretty large street port done to the car so wouldnt i need to remove most of the rats nest to do this?

 

most people do, but you don't have to
