Been reading and see that cams on other celica engines can really boost them.
I have been looking but cant find anything
Does any one have any ideas for upgrading the 7afe? I dont have the money for an engine swap!

I did some simple things but I dont know what to do now. I put a cat back on and a CAI (i know there isnt much improvement there)

I'm sure you can get cam grinds for almost any engine, you just have to research what the new ones will be grinded too etc, you will generally get 20hp gains so in terms for value of money it isnt very good as its an expensive job.
