Hey, i have a 85 ex cap, 22r, and i was wondering how i could get more power out of it, i herd that droping in a 3rz will work, but im not sure what i have to do with that, like does it fit in the bay just right? or do i have to make new brakets? i also herd a new exhaust will give me a few extra hp, and a K and N, but ive read some things about a K and N not being worth the money.
