While working on the swap project, I discovered that the stock
civic radiator's fittings were smaller than the B18C1's fittings.
After a few attempts at rigging the stock radiator, I ended up
double clamping the hoses to try and get them to work.
Unfortunately, it still leaked.
While researched radiators, I discovered that the Del Sol VTEC's
radiator would be the only radiator that would have larger fittings
and fit in the stock position. Just a quick note, the 6G civic Si's
radiator is the same as the D16's radiator. The only problem with
the Del Sol's radiator, is cost as a new item and unavailability as
a used item.
After doing more research I discovered Fluidyne. Fluidyne offers
a very thick aftermarket radiator for the civic that includes the
larger hose fittings needed for the B18C1. Upon inspection, I
discovered that the quality of this radiator is outstanding. Aside
from the difference in thickness, the radiator dropped in using all
of the original hardware. Fittings were also welded onto the
radiator to simplify the installation of the cooling fan. Truly a
work of art.
I do not have any specific numbers regarding the "performance" of
the radiator. In all honesty, this radiator far exceeds the cooling
necessity of the engine. However, in the event that I go turbo, or
heavily build the engine for NA performance, I will have a radiator
that will successfully accommodate my cooling needs.
