[Roadsters] Which radiator should I use

[Jerry Krakauer]

I agree with Gary's opinion.  Even with hard driving, I never had a problem
with the stock radiator in my 67.5 Solex. Even in my early racing days had
sufficient cooling. Only after I stepped it up quite a bit did I encounter
overheating. But that was a doosy, actually melted tracks in the head on two
cylinders between the combustion chamber and water passages at a race at
Bridgehampton. Even then, if I backed off just a bit the temp would come
down; but I was really pushing it...battling for the overall lead with BP
small block Vette. Needless to say, along with the new head came a custom
radiator.  BTW, that old rare non-smog head has served well as a wheel chock
for many years.

Chuck,

Gary's opinion:

A properly functioning factory radiator, combined with a 1600 or 2000 
roadster properly equipped with pre-emissions ignition parts and set to 
pre-emission specifications, will provide sufficient cooling under most all 
circumstances.  I believe it is generally less expensive to find and fix 
whatever underlying problem is causing the overheating than it is to start 
installing aftermarket parts.

I took my original car, a '66 1600/U20, through summer heat in the 
California and Arizona deserts without overheating back in the '70s.  In 
2008, I drove my (newly-purchased) '67-1/2 2000 through stop-and-go traffic 
in downtown LA in the summer heat, and it never went over 190F.

I think Nissan generally knew what they were doing.

I am sure the foregoing will spark plenty of controversy.
