I was looking under the hood doing some fitting in my head, id keep the turbos as high up as possible also go nuts on the temp wrap. I say this because of any water that you hit riskes cracking your exaust houseing on the turbos. As for the I/C have you thought about water to air that way you can mount your heatexchangers any were you want and make the plumming take up less space, even routing your a/c to cool would be worth a try. Who was it that played with that, I think Ford. Just some thoughts. If you want I can look into some of the different water to air I/Cs, do some figuring on size, I think the size were going with would be a good start, there 2 3/4 inches thick by 9" by 6". Were just getting the cores and welding on water and air tanks. The air tank design is important so you dont get hot spots.
