Ok, so on thursday i will be swapping a b18c1 into my 95 del sol s...i know they are two completely different radiators (the del sol is smaller). Will i end up overheating much or will it be ok. Thanks.

 

It'll be fine. I've personally seen it done multiple times. But you will need adjustable hose clamps to squeeze the rad hoses around the civic rads smaller inlets. A Del Sol Vtec rad is the ideal solution though, drops in exactly like the stock rad, but its dual core and has the larger B-series inlets, but again the original rad will work fine.
