okay here's the deal.
you can build a fast NA f23, you can do a h-series head swap, up your compression and be pushing 200+ hp, but the fact is that without drop, without upgraded suspension more of that power is gonna be lost in the transition from the bell-house to the wheels
to be brutally honest, you're running 18in rims, you're talking about deeply tinted windows, to me it sounds like you want a slow roller to show off. if thats the case, get some k-sports or f2 type-II's. get a lip kit, check out the members rides for ideas
do your research and figure out what you want, you don't need us to answer those questions for you
