HID conversion kit questions

[saiful]

My first post. I have been looking at the forum for a while and love all the cars. I have an '01 2.7 Red, and absolutely love the car. I'm looking at several HID plug-n-play conversion kits. I've decided to go with 6000k.

My questions involve installation. Which specific kits have others bought? Would I need to drill the back of the headlight backlid/cover? Does the ballast fit in the headlamp casing or does it need to be placed in the front trunk? Here are some of the kits I'm looking at:

2) http://cgi.ebay.com/ebaymotors/Porsche-Boxster-996-Xenon-HID-LITRONIC-Conversion_W0QQcmdZViewItemQQcategoryZ36476QQihZ00 7QQitemZ170171338417QQrdZ1QQsspagenameZWDVW

The second option is quite a bit more expensive ($250 vs $105). Is it worth the difference to get 2 pre-drilled headlight backlids?

Thanks,
