Do you want it hidden or 'out there' for the world to see? If you want it "hidden" I'd suggest the passenger side fenderwell, behind the shock tower and under the hinge. Paint it black and very few will notice it. Want it seen?... Put it on the radiator support, driver's side, outside the engine compartment just behind the grill (opposite the voltage regulator). This location will be visible even with the hood closed and will also help to keep the unit cool. The coil can stay in the stock location.
I hung mine on the driver side fender, and then slapped an overflow can right on top of it....there have been quite a few people who haven't seen it and asked why I wasn't running an MSD with my motor setup ::
