Some of you may already know all the crap I've been though with this JDM swap, well God has sent me another swift kick in the behind. I was driving on the Freeway for the first time, and I was cruising at 3K RPM (JDM 7MGTE/R154/4.3 LSD) I went to turn around satisfied that my swap could handle it, as soon as I got off of the freeway the temperature began to spike. I pulled over into a parking lot and rushed outside to see what had happened. Coolant all over my hood, but everything around the enigne was dry. I looked in the overflow and it wasn't boiling over, I had just topped it off yesterday after adjusting some coolant lines. It had dropped a bit. Nothing to worry about right? So I turn the car off and low and behold, lots of white smoke coming from the Radiator. I squeeze the radiatior hoses, and they are still pressurized, so I'm standing there scratching my head and praying that it's not a BHG. So I let it cool off and decide to leapfrog it home. I start driving it and it spikes after about two minutes coming up from about normal operating temp. So I let it cool off again and decide to try something risky and leave the hood popped and blast the heater. On the freeway ride home it stayed at nomral operating temperature, but the second I stopped and closed the hood when I got home, it started spiking again. I drained the oil, it smelled normal and looked like I was expecting it to; black due to the diagnosis process of getting the damn thing running right. So that leads me to believe that it's not a BHG, but I could still be wrong. When I would try to start the car the check engine light would come on in the first three seconds of idle, and once I gave it gas and let it idle again it went away. Checked the codes, 24 & 31 which are the Air Temp Sensor and the AFM. I'm pretty sure these problems are unrelated, and I have a spare AFM, but it's not like I can drive it with my new AFM to see if it still throws codes with this Cooling problem going on. When I started it this morning before driving it, I got the lovely waterfall noise in the dash from the heater core, which was clogged yesterday, but seemed to magically heal itself 
dunno Originally when the car was NA it was running green, but when I converted to turbo, I stared running the red, and yesterday was the first time I ran the heater since the conversion.
Sorry, I know the post is long, but I wanted to make sure that I didn't leave anything out. I hope someone can give me a little insight here.
