Both are doing fine. Too scared to run the air-con in the Pulsar until I can properly monitor my temps (ie. when I get the Defi's installed) as there's so many cooling devices in my engine bay...and stuff all room for heat to escape. There's a massive truck sized FMIC, radiator, stock oil heat exchanger, air-con condenser and two transmission coolers all in the one spot (not the mention the bigger turbo sits close to my radiator)...and the engine was never designed to be in such a small bay in the first place. Poor car The Skyline is obviously running a bit hotter than normal, but perfectly normal temps. Plus I can run the air-con in it all day and not worry, it's a fairly stock car. It's nice to have a stockish daily to pot around in, air-con ftw.
