Is that Mishimoto a full size rad ? the half rads work in cooler temps but it will be a problem or at least it was for me in temps above 80 or so the thing ran hot especially after beating on it.I have only been able to keep the temps in check with a full size rad in the summertime. I just looked and don't have any pics of the bungs on my oil pan but mine are above the oil drain plug near the top of the back of the oil pan .oh btw nice chassis !
