Ernest, have you check the diameter of the cross flow tubes. The reason I
ask is there was a comparison of Ford and GM evaporator cores in Contact!
mag a few years back. The end result was the Ford cores (at least of the
1970-80 decade) had cross tubes too small to flow coolant without a
tremendous amount of restriction. The GM cores had cross tubes of over 1/8"
diameter and did much better. The net results according to the article, as
best I recall, that made the Ford Cores unsuitable for our needs. No
information on Nissan AC cores. I believe it was in issue #43 or 46 and I
can no longer find mine (stuck in a safe place no doubt)
That is my biggest worry about the whole thing, Ed. I could possibly use two, plumbed in parallel (I have plenty of space for that), or I may just have to scrap the whole idea. Basically, though, I'm working off th idea that a thinner radiator with a larger surface area will have an efficiency advantage and require less radiator volume for the same amount of cooling.
Unfortunately, I have a lot of time to work on this part of the project.
