engine question

I have a D16Y8 in my civic and I know there's a lot of debate on this, but I would like some your feed back on eather tuning this one up or swaping. what have you guys had best results with. Taking into acount drivability in winter time and afordability. basicly if I were to swap, what engine would give me the most hpw. yet still be a somewhat simple swap. Or If I was to tune this one up where should I start? Thanks every one you all have great info.
