Alot of info, thanks guys

I'm not modding it for the sake of it...actually want some more power out of the engine and all..on student funds too so i don't really want to spend all my money on the car else ill be struggling to even afford the car..

right now i think 2.5 from everyone views and opinion is a good go...althought i did want 2.25 from what most people was saying.
Its guna be really loud but i guess ill just change the muffler later on

Thanks guys!
