What's a couple of ways to add more power to my 2013 Honda Civic EX?

Besides new intake and new exhaust, how much horsepower could I push out of this 1.8L engine without blowing it? What are other ways I can do this?

If it's an EX that's not even a V-tec is it? I'd just do the basics and that's it otherwise you'd have to spend a lot.

Take the engine out, throw away your warranty, spend 10,000 bucks on gofast parts and tuning.

Pour powerade into the exhaust pipe.

Trade it in for a Civic Si?

You can chip it. That may add some horse power. Probably cost a couple hundred.

Trade it in for an Accord V6
