I currently have a greddy kit on my 95 civic and I wanted to know what size intercooler I should buy. I am running the stock boost right now with plans of adding hondata and uping the boost to 10psi. What size intercooler would be best for this application?

-31" x 6.5" x 3" Intercooler with a Silver Core Blackstone Core.
That is the intercooler that is being offered through swift performances group buy.

It is a good deal, but is that intercooler too big for what I am trying to do and if so what would be the best size for me to run? Thanks in advance.
