If you do a projector retrofit go with mini d2s projectors. Most writeups I've seen use FXR but I think minis are easier to install. They fit in the same hole where the stock bulb goes, almost no cutting of the housing and the lens is the same size. Oh and you should get a set of 99+ headlights with clear lenses.
Your housings will spray that light everywhere, and not necessarily in a good way. I love having projectors so I can high beam people driving with blue and purple headlights shooting all over the place, don't be that guy.
So much this. Whenever people talk about re-aiming the lights down to eliminate glare, they're so full of crap. They're also negating the point of trying to increase light output because it just points it all at the ground. Either go projectors or don't do it at all.
I had a pnp kit for a few weeks, and I was able to modify the cutoffs to get a sharper line than the stock halogens, but the light output is nothing compared to a real projector. Id recommend the d2s 3.0 or the fxr, but if you do the fxr its difficult to install and get straight.
FX-R isn't too hard. Just find an appropriate place to check the cutoff and make appropriate tweaks before sealing everything back up. Here's what I got on the first try with my old Subaru.
its not hard its just difficult to get the projectors perfectly lined up in the housing since you have to drill the holes in a non flat surface. the d2s 3.0 fixes that issue by aligning the projectors in the existing hole. the only freedom of movement is rotational.

Even then they include a centering plate that is the same shape as the stock halogen bulb. Although I had to cut off all those groves and things that center the stock bulb, the centering plate helped a lot.
