I don't have projectors, why are they necessary for HID's? My buddy put a set in his Sentra SE-R and they look fine, nice and bright. My neighbor has done the same with his Civic SI and they're crazy bright. I've read up on the topic, HIDs run cooler than a stock halogen bulb, so no worries about burning the headlight enclosure. So what's the big deal? I'd imagine the light coming from the HID bulb is nearly the same as a stock halogen, only brighter.
