Im 17yrs old in new jersey and im looking to buy either or but i want a car good for everyday use and racing. Light and upgradable. I have heard the Si is more upgradable motor wise because no welding has to be done to install motors, what motors are they. The 92-95 hatchback is all good because many parts are made for it. i need help and what are good mods to add to each car and what is the most hp i could get out of each car and how. THANKS!
