I have recently got a 1990 acura integra ls from my cuz locked down. It is basically stock. I want to know what are some good mods to get it runnin good, have power, and be able to eat some people up. Also is there any difference between the us version and japan version of this teg. BC i have the japan version. Can I turbo it? Fuel rail? I want to know also what is the difference between short ram and cold air?
