I was going to get a larger heat exchanger like the one nissan crazy listed, but mine seemed to work fine for how much water i had in the system. My total system volume was 5 gallons.
I used a jabsco pump as well i had the pump for 3 years with no problems wired ona toggle switch. I like the fact that their pumps are brass and rebuildable, you just thread in the npt fittings of your choice and go. Alot of the other brands pumps just seemed cheap to me, and not very robust.
I didnt care much about the ac in my nx, 90% of the time i drive it i have the t tops off, and usually leave them at home. So i ditched the ac as soon as i went turbo quite a few years ago. One thing i always wanted was a low temp water temp gauge, or 2 air intake temp sensors to see what the temp was before and after the intecooler and see how effective it actually was.
