I have just recently decided to install a b16a motor into my 91 CRX Hf, but before i was able to purchase one, my radiator cracked on my stock engine. I have another stock Hf radiator that i can get a hold of for cheap, so i was wondering if i could use the stock radiator for the swap or do i have to purchase a higher performance one?

 

You could probably run the HF radiator assuming it is in good condition, but under any hard driving conditions it may overheat.

I would highly recommend this: http://www.absoluteradiator.co...rod=9
2nd to last radiator on the page, double the stock cooling capacity for $122.

 

thanks ill try that CFS radiator
