honda crv vs non turbocharged subaru forester,which one is more energetic? thanks ive narrowed it down to these two

I want to add more HP to my Accord coupe but I dont want to get a turbo kit. (not yet anyway) I would like to add 40 HP to it but Im not sure how or if its even possible. I already plan to get a catback exhaust and a short ram intake but I know thats not gona bring it up 40 more HP. Any suggestions? The more details the better

Right now i currently have a 92 civic sedan with a skunk 2 exhaust, a 4-2-1 header, and a cool air intake on a d15b7 motor. I am looking for suggestions as to what more can i do to it, besides turbocharging it, or replacing it to improve the performance i got out of it.
