I just got 1992 Accord LX for getting my drivers lisences

...its auto with 108 miles on it and i wanna do some engine mods, but

I dont know where to start or what to get or what to do...Can anyone help me?
(and I'm kind of on a budget cuz im 16 with no job and i have around 1500 to spend)
-edit-
I'm not planning on doing a engine sawp with a H22A but im lookin into it and i was wondering...Would that be a lot better? Where can I get a cheap one online?
Thank you to all who replied
