Any DIY power up for a toyota 3a/-c engine

I got a tercel with a 3a type engine that needs some performance upgrade all beacause I dont really think 80hp est is good now days.
So does anyone got ideas on DIY performance upgrade

Might want to post in the toyota section instead, I'm sure there'll be alot of ppl there to help.
But honestly, I don't think its worth throwing money on that engine, maybe consider swapping for something else instead(if at all possible). I guess you can strap on a turbo or something, but that'll bring you to maybe 130-140, since you are saying you only got like 80 now..
