well i have a 19x16 full size dual flow radiator out of a 70 nova. its at the top of the last page or a handful of posts before your post. can see it laying down behind the bumper under the turbo. ill be running it. i considered rearmounting and it can lay flat under the single turbo setup like this. also twin civic rads off ebay will work side by side around the turbo behind the grill.
