as far as crankwalk goes,dont sweat it, if it happens, it was meant for you to be to get a 6 bolt, but i wouldn't count on it happening, and heat soaking occurs w/ the stock intercooler basically cause it blows monkey nuts, supra intercoolers are good, therefore, you wont get heat soak, a guy i know ran a big 16G with 20+ psi through one and didn't heat it, dont sweat it
