I was in the same situation as you are (school/engine is fine).so i promised my parents I wounldn't get it done until my K8 died.
It's a game of symmantics really. The agreement was to not *DO* the swap until your K8 died. There is nothing wrong with still buying the ZE, having it on a stand, and building it up for when you're ready to swap it in.
**THEN** When you're ready to swap it in, just put on some tunes, grab your favorite sledgehammer, and go to town! When your parents asked wtf^^?
1.) I couldn't wait anymore.
2.) Trying to catch a butteryfly...
3.) I saw Dennis Leary do it on TV.
4.) Throw a beer bottle and tell them you're gonna burn this mother down.
5.) Those silly pink bunnies...they ALWAYS know how to mess up a good time. (followed by some twitching and eating of eletrical tape in big wads & drinking of motor oil)
