S15 NA Motor

[SoCalSilvia]

hey guys, first off, if this is supposed to be in Tech, forgive me and mods please move.

Now, I was searching today on these here Zilvia boards about the NA SR20DE and I saw in some post(which I can no longer find of course) that the S15 NA SR20DE puts out 200HP. Does anyone know anything else about the NA S15 engine? I know that is a broad question but I guess some of my initial questions are:

1- will it pass smog? It's not going to change my mind if it doesn't since I am already thinking that it does not pass smog.

2- I assume it is direct swap into S14? Would that be correct?

3- how is the aftermarket for it? Can I use parts for the S13/S14 SR20DET?

4- Since the S13 SR20DET puts out 205HP, wouldn't it be a "better" idea to get an NA that puts out almost as much?

5- Will I have to buy only S15 items or will I be able to use a tranny from a S13/S14 SR for example?

Any help is appreciated. Try to keep the flaming to a minimum, just trying to gather some information here. Oh and yes I DID SEARCH!
