The link above is for an RB20 swap... but should be a good referance for you.
As in the other link.. I would suggest an adjustable fuel pressure regulator.
As for the radiator... I got a new 240 radiator instead of the high capacity Koyo... I have two electric fans and have never needed to even turn them on!
Hey... your in Milwaukee!. Give me a shout when you decide to start working on it. I would love to see it. I would love to help as well. I am a pretty novice mechanic, but perhaps I could be of some assistance. I am in Green Bay, so it's less than 2 hours drive.
Good luck with everything!!!
