Hey Im planning on running piping from the intercooler up the passenger side where the battery/overflow tank is. Ive seen it done more than once, so the main question is what to do with the overflow tank, and what kinda overflow setup is needed?

 

You can just take it out and pitch it, as long as you move your battery to the trunk. As for an overflow set-up, just run a hose straight down and have it flow out onto the ground. That would be the easiest.
