tips on 97 prelude

Okay so i have a 97 prelude it's the base model and i was wondering if i could get some tips on what is some good perfomance upgrades. I already have a aem intake, dc exhaust, aem cam gears, skunk2 coilovers, konig rims and a not completely installed zex dry nitrous kit. Also anyone who has run nitrous and could give me feedback on how the engine handles i would appreciate it. Oh i don't have alot of money to spend at the moment as i am saving to move so any cheap upgrades would help.
