CAN U TELL ME WAT TO DO I HAVE A CIVIC LX 91 PLZ HELP:confused:

Do research. Seriously, do a ton of research. If you do what other people tell you to do, you'll be building THEIR car, and you'll never be happy with it. There are so many things you can do to your car, in all different power ranges, and all different budget ranges. If you do a lot of research, you'll be able to figure out what it's going to take to reach your goals.
