well its weird, the instructions show a little picture of tapping into a existing vaccuum line with some kind of kit for the s15 install. none of the vaccuum lines run off the cold pipe before the throttle body. it has like a paragraph of info in japanese what you are supposed to do but i cant read it lol. i dunno if the kit comes with some kind of valve or what not..but ill try to call greddy or go weld a nipple on my hot pipe =/ i dont trust myself tapping something so thin.
