What other upgrades can I have?

[typiko512]

Hello, this is my first time here and I'm glad I found this place cuz itz got lotz of info... Anyway, I have some questions 4 you guys if yall don't mind answering em

I recently bought a 94' Integra gsr (2 dr) and it came with:

DC Ceramic headers
RS.R catback exhaust
Sway bars front and back adjustable
Lower Springs
momo rims

Then after 1 month of purchase, I bought and have these installed:

AEM Cold Intake
AEM Pulleys
AEM Cam Gears

And today I just got my valve adjustment and rotor/cap changed, radiator flushed, trasmission oil changed etc. (tune up) since it has almost 120,000 miles on it.

Besides the tune up, is there anything else I need to do to maintain my car in a good shape and good mileage?

Now my question is: Any other upgrades I can do to boost the performance (HP) without spending too much money? I don't care about the looks for now though I am looking for new rims for my car. What size should I go for and what kind will look good on a white gsr? I heard I can ask to do the polish for the headers and intakte and stuff so I might get some hp off of it. Maybe the flywheel will help? Nothing too expensive like piston upgrade or the turbo. Something like flywheel price range will do. Hope this explains my Q's. Thanks! Appreciate it...

PS. I'm willing to spend another $500~$800 under the hood so if yall want to know the price range...

Thanks again.

Oh yeah, forgot to mention that I also bought the NGK spark plugs/wires and have em installed also. Umm... I think that's about it.

a new ignition system would help...
