I'm contemplating ditching all the engine bay components of the air con system but from what I have read through searching, there's only 10kg's worth of gear and bugger all gained from not having the belt attached. Sound about right?
My car is a dedicated track/fun S13 but it is still street reg'd (though not road worthy I'm sure). I've done some basic weight reduction stuff like removing all the boot stuff, spare wheel, jack, rear seats, rear speakers and parcel shelf, upgraded the drivers seat and put some volks on it but that's mainly in the rear so any more weight removed should probably come from up front.
Who has done this and what did you actually find afterward, worth the effort? The issue for me is not comfort as I don't drive it on the street but more about re-sale when it comes time to let it go.
FYI my car is only a CA18DET with a turbo back exhaust, front mount and a bit of boost. I realise I will gain more from a turbo upgrade etc and that's coming, just interested in the air con removal for the moment.
