( please don't post nething about swaps/new car/or turbo cuz i dont have the cash flow for that kinda stuff i dont want a hot rod i was something to get around in with just that lil extra kick for those straight aways ^_^

hate to shut you down but first

power and cheap dont go together
search for yourself ( use what the forum already has)
own the car for a little bit before you know you want to put money into it
