I am looking to swap out my dual core rad for a full sized Integra Unit. I desided I was just going to get a full on Koyo Race rad, and just remove my hood latch so that I can move it forward more and still run a turbo setup on the B series. Now, Koyo offers 2 different versions for the 94-01 integras a Denso one and a Showa one, I was wondering if anyone knows the differance between the two, and if so which would be a better choice.
