Does anybody know the dimensions of the greddy turbo kit for a 92-95 civic si. Also what exactly is the difference between the 24V and the 31V. I allready have the greddy turbo kit and would like to know how much more hp i will get out of buying their intercooler. I found a OBX intercooler for cheaper and wonder if i would be better off just buying that? I know OBX is not as good a brand but i'm not sure if someone could give me heads up on their intercoolers.
