Hondas are good cars but you will never feel like your going fast, Besides top speed.
Ive seen 750+ hp civics but the torque was always 35-45% less.
Anyway, you can prolly get a chip which will remove the speed limiter on your stock ECU and allow you to kick higher on the topend.
If your willing to drop a couple K, go for a turbo.

Ps. hondas can be very fast if tuned properly...but they will always seem soso from the cockpit since the TQ numbers just aren't there.
