what advantages and/or disadvantages to removing stock radiator (from a car with a full size radiator) and putting in a half-size radiator, say from a del sol or civic?

 

We'll first of all. The half size radiator wont fit a rex with out a custom mounting setup and an aftermarket cross member. Other than that, it works fine on the street(i've done it). I ended up getting rid of it tho' because the car did not run cool enough when racing.
