"It has been widely accepted within the 240SX enthusiast community that the SR20DET engine has a tendency to overheat. As a result of this, numerous companies have made various products available to aid in increasing the cooling capacity of the SR20DET and thus decreasing the tendency for the engine to run hotter than desired. However, with the introduction of a number of these components, there has been no substantial testing to quantify their effectiveness, nor has there been any sort of testing to rank the products in terms of performance superiority...."
Test subjects;
Radiators: 1.) Stock SR20DET radiator
2.) Koyo Copper and Brass
3.) Koyo Aluminum
4.) C&R Single Pass
5.) C&R Double Pass
Fans:
1.) Stock SR20DET Mechanical
2.) Permacool (Single fan with no shroud)
3.) Flex A Lite 220 (Double fan with integrated shroud)
4.) 95 Nissan Altima (Double fan with integrated shroud)
5.) SPAL 13” Low Profile (Single fan with no shroud)
