My car has 16valve 4cyl 1.9L in it, i'm looking for new engine and trying to figure out my options as far as bigger engine that will fit in it and or just getting either Turbo or NOS, what would be the best way to go, and is there a bigger engine that will fit? any help would be much appriciated

 

Just put a 454 big block in it. They bolt right in. Just lift the old one out, and put the new one in and start it. Done!!!
