2007 ac swap, will update untill finished/solved

Great write up and kudos for paving the way on this. I'll admit, it seems to have cost a lot less than I would have thought.

Quick Q for you and my apologies if you already answered it: why did you not just fill the a/c based on weight and essentially be done with it?

I understand dialing in pressures to potentially improve performance over factory specs, but as a starting point why not just use the factory fill weights as a baseline?

IME Japanese manufactured vehicles were never designed to have proper ac cooling at idle, they are sized for efficiency and to perform once driving.

All Japanese vehicles I've owned (Toyota, Mazda, Subaru) have decent ac at idle (~60F vent temps) but improve quite a bit once moving (~45F vent temps). This makes sense as having an ac system that works great at idle means you are just burning gas in the other 90% of times you are using it and actually driving.

i did initially fill to spec, but im not sold that said spec is for a "fresh install", as it wouldnt get up to pressure to kick the pressure switch, of course i also think the new valve is at the condenser is semi faulty or sticking which could have caused the false start and lack of pressure, its rated as an oe replacement but with as sensitive and slow as it is im probably going to empty the system and re-fill again with a direct denso part in its place

I apologize if my reading comprehension is not on point:
So you installed an A/C system into a car that did not have one?

You're a madman, and you have my sincere respect.

sure did.....and boy oh boy is it nice to have, tho i have to admit you can FEEL the power loss at low rpms, anything above 3k its not noticed unless your going up hill


adding options where they wernt is always fun and useualy not so "plug n play"....while i was in there i noted it looks like the harness is there for power windows....when i find them...but thats quite the rabbit hole with needing all 4 door panels, motors, switch panels switches and harneses
