soo im 18.. got my first honda! its a 91 civic hatch. right now it has d15b2 with i/h/e and short throw.. i know a bit about hondas and whatnot. but not sure what to do. i want more power, but i dont have ass loads of cash. so i would love some recomendations. idk whether to do a vtec head swap(mini me), a full vtec single cam motor and build it or swap a dohc.. suggestions would be great. oh and if anyone can explain the whole obd thing to me thatd be great too thanks!
