HID for S14A

[matt0941]

Ok after reading one of the most informative articles I have ever seen here I learned alot but feel left hanging. I have an S14A (projectors) and want to do an HID conversion. But as the article states, an HID optics swap (such as a projector/reflector headlight assembly designed for HIDs) in addition to the HID bulb and ballast would benefit myself more.

I am looking for projectors that I can replace the stock H1s with as they have been said to not comply that well with HID kits. Does anyone know if something like THIS would fit well in the stock housing? Because I have heard that 3-series work fine but is this any different?
